Title: UberBuss and DigiBuss
Post by: rollo on July 18, 2026, 12:17:37 PM
AI says Uber has isolation trans in it. I think that is incorrect. Also instructs me to Digi into Uber and Uber to wall. Then it tells me to plug Aqua Cd transport into Digi. Plug Lab12DAC into Uber. I'll give it a go for kicks and giggles.

AI is wrong.  There is no IsoTX in an Uber.  None in the Digi either.

It looks like AI might need to take some remedial classes 🤓

Thinking about the UberBuss but Dannys cable is a garden hose. All my cables are TWL maybe Pete or Dave can chime in on which TWL cable to use

It's less about the diameter of the cable than it is about gauge/flexibility.  The GR cable is pretty stiff, but more than capable. My old Mongo is ~ 1" in diameter but flexible enough to tie a 5' cable into 3 knots.  Pete's cables are also pretty thick, but they are still supple enough to route easily.

For wall to Uber I recommend any of TWL heavier gauge cables.  The Obsession is stunning, but pricey.  The Seven Plus and High Power Digital American II are great choices.

Pete? 😃

I agree with Dave's assessment... either the "HPDA II" or "7+" would work fantastic!

Yes my Uber has 8 also. I wanted to separate the amplifiers and the digital. I will leave the digital hooked up to the puritan labs, and all my amplifiers and preamp be plugged into the uber. One thing I did notice with the uber is that the soundstage is not as deep as when it was hooked up to the puritan labs.

This morning depth has returned and the micro dynamics are unreal. I am listening with my Pass Labs XA25. I have never been a fan of this amp since I purchased it. It's about 1.5 years old and maybe 20 hrs on it and now plugged into the Uber I am really enjoying it. I will plug my other amps into it later in the day. My toes are finally tapping to the Pass Labs.

Am I the only one that purchased a BlunderBUSS with 24 outlets from Dave?  :shock:  :D

I need a lot of outlets for the line array Class D amps, 4 servo Class D amps and DigiBUSS for the dspNexus 2/8 DSP Control center.

So you will likely sell the Pass? I like the Starkrimson, but don't want to switch from the Elvis, at least for a while. The Elvis is quiet, resolves beautifully and has a nice rich midrange. What amp(s) get most of the playing time?

I've always been told to hook up the amp directly to the wall socket and thus have the Coda #8 in that scenario.
Should I give it a try though Daves marvelous Buss? I do have a Digi pluged into the Buss and use it for front end equipment and love it.

I'm finding that with the Orchard amps plugged into the Uber the overall sound is in your face and not as defined. Plugged into the Puritan the sound is more natural. Pass labs plugged into the Uber the sound is more natural with a quieter background than plugged directly into the wall or the Puritan. I'm wondering if this is because of the difference in power supplies. I know Chat GT is not 100% but it says that the higher power components should be plugged into the Uber and the lower powered stuff in the Puritan. It also says that if using both I should plug them into different wall outlets which I am not doing. I did not like the sound of Orchard with my preamp plugged into the Uber but with the pre and Pass Labs amp plugged into the Uber it was a winning combination. Instruments had more detail and a quieter background. I still have more hrs to burn in on the Uber and sorry if there is a lot of run on sentences so I will see if anything changes in the weeks to come.

The SMPS in the Orchard are the culprit.  They simply don't like a PFC network in series with them. 

The Puritan uses the more common method of noise reduction with inductors , etc.  no matter what Puritan says the result is current limiting and phase shift.  You can't get around physics.

The reason I developed the DigiBUSS was to be used specifically with components with SMPS.  It is (was) the my only device with inductors.  The common mode line inductor used is rated @ 25A / 250VAC.  Resistance is .003ohms.  The primary purpose was to eliminate back EMF being introduced the circuit.  It also reduces line noise from wall warts, dimmers, appliances with always on demand sensors and so on.

Nearly and here's what I am considering.... I will be getting an ultra low noise 5v lps for the iFi optical converter and am thinking about trying an ethernet cable to replace the LINKUP between the TP Link mesh unit and the iFi. The cheap ethernet cable I had obscured a lot of detail and air. The LINKUP is quite an improvement and I am curious if I can get a bit more performance with another cable.

While I suspect based on my experience with the Orchard amps and the Reynaud AMT tweeter that the introduction of the Elvis tube amp took you closer to what you are looking for I'm not sure you are going to get to where you want to go with a SS preamp and changing an Ethernet cable.  I know that when I periodically put the Holo Serene KTE SS preamp back in the system that "timbre" is the first thing that goes away no matter how "accurate" the sound becomes.  To my ears that "timbre" you are looking for will come from a tube preamp before it comes from anything else with AMT tweeters. Again just my opinion from 5o+ years of experience.

Shoot, I was hoping you wouldn't say that. The solid state Hattor pre is terrific and better than the tube Supratek Chardonnay. Those are the two best preamps I've owned. Getting into an Aric would be pricy and take a while. I like Holger's amp a lot, but don't know much about his tube preamps. The lps for the iFi is worth getting as it's inexpensive. I will likely try 1 or 2 ethernet cables and hope it can bring a little more of what the UPLINK provided.

Actually from looking at the Erhard reviews it's the preamps that get the most accolades and have the lower price points. This is the one that would fit what you need. I've discussed the preamps with him several times but for now I don't need another one. Unfortunately as good as Aric's preamps are they are at least twice as expensive with a six month wait time.

Im still using the Link up cable. When Pete was here a few months ago he said to try his cable from.my switch to the streamer. He said no need from the wall to the switch. Its the only cable I have that isnt TWL.  Its not expensive either just havent got around to replacing it yet.

Based on the sound of Holger's amp, his preamp is likely to be very good. I took a look at the link and the parts and quality look very good. The only problem is the attenuator. The stock version has a manual attenuator and an option is to use an Alps that has a remote. I don't want to go back to using an Alps as that is what the Chardonnay had. The dual mono remote that Arek from Khozmo offers is much better as to the quality, digital readout for each channel and functionality of the remote. So if I ever go to a tube preamp, it would have to use a better attenuator with remote control capability.

I took a look at the Aric Audio website and the single and dual mono 6ns7 versions. A lot more expensive and he uses the Khozmo remote. It is the 48 step rather than the 64 step unit that my Hattor has.

So I will keep my Hattor for a while and just see what a better quality ethernet cable can do.

I just called Pete and a .5m ethernet cable will be shipped next week. I am also seriously considering trying a silver ethernet cable. I enjoy the sound of silver and have some in my system. I have also tried the Neotech gold/silver wire with great results. Pete also uses a cable cooker which I really appreciate.

Maybe so 😝 They offer other cables as well, but not as highly rated. These are also shielded, so I'm curious what an unshielded cable like Pete's will do.

Unfortunately as good as Aric's preamps are they are at least twice as expensive with a six month wait time.

https://www.erhard-audio.com/Visio.html

Based on the sound of Holger's amp, his preamp is likely to be very good. I took a look at the link and the parts and quality look very good. The only problem is the attenuator. The stock version has a manual attenuator and an option is to use an Alps that has a remote. I don't want to go back to using an Alps as that is what the Chardonnay had. The dual mono remote that Arek from Khozmo offers is much better as to the quality, digital readout for each channel and functionality of the remote. So if I ever go to a tube preamp, it would have to use a better attenuator with remote control capability.

I took a look at the Aric Audio website and the single and dual mono 6ns7 versions. A lot more expensive and he uses the Khozmo remote. It is the 48 step rather than the 64 step unit that my Hattor has.

So I will keep my Hattor for a while and just see what a better quality ethernet cable can do.

Aric put the 48 step in mine. he said it's cleaner sounding.
Great about the TWL cable. I will wait for my commision :rofl:

I could live with the 48 step. I think the 64 step is for dual mono like my Hattor. I misspoke previously as Aric offers a two chassis preamp and not dual mono.

I thought about that. I believe you thought it was on the neutral side. Maybe it's similar to the Holo Serene. I would be leaning toward the Aric.

Compared to the "old school" tube sound of the Chardonnay it's more to the neutral side but that can be adjusted with RCA black plate tubes in the two input slots. Then it becomes more like the Cabernet. It really has nothing in common with the dead neutral Serence.  The Serene would be more aligned with your Hattor.  The Aric's can be more neutral if you put the right tubes in it like the NOS Tung Sol's it was shipped with.  Replacing those with the smoked glass RCA's changed that.  The rest of the gear in the chain including the cables also have a huge affect system to system. The Sachs would be much warmer with either of your amps than the Hattor.

Thanks for the additional information. Any preamp change would be a ways off. I don't know if Don's preamps are still being made. Is he now affiliated with another firm, is he semi-retired or completely retired? I don't know. I know you went to the Aric preamp and it appears you prefer it over the Sachs. All things considered, I would probably go with the single chassis Aric of ask Holger for a custom order using the Khozmo attenuator and remote.

I do like the RCA 6ns7 tube. It resolves and has that mid range warmth as well

Don is retired from his own company but does consulting work for the new owners at Spatial. 

If you are considering trying to get Holger to use parts from an overseas company he has likely not done business with before I would ask him way in advance of deciding to buy a preamp.  From my discussion with him about preamps he will do some customization in terms of inputs and outputs but I didn't ask about anything else.  Also the Khozmo unit may or may not even fit inside of his preamps with the way they are laid out.  The same thing Mick said.

Getting Holger to add a Khozmo is a long shot I think. But I would ask as it's my first choice, mainly because of price and I think it would sound very good. The single chassis Aric is $4,995 and I'd prefer not to go that high. The Erhard pre would need room for the attenuator and the digital feadout. I am guessing he probably would not want to do it. But anyway, not a priority. I will be adding the LPS you recommended for the iFi optical and will be getting Pete's ethernet, so I'll see what changes there will be.

I don't think the Alp's Blue Velvets are all that bad especially the top of the line model that Backert uses.  As for digital readouts they can just add noise so I always turn them off and adjust by ear.  And yes the Aric's are expensive compared to Erhard plus you put down 50% up front and wait up to six months for delivery. I've had the Rhumba and the 25s back in the system for the last week or so due to the heat and the combo sounds great to me.
Title: Re: UberBuss and DigiBuss
Post by: Nick B on August 13, 2026, 10:38:57 PM
You know I liked the Chardonnay. I just liked the Hattor better as it resolved better. It's also uber quiet with or without the digital readout. I do find it very handy to see the volume numerically displayed. My concern in getting a unit with an Alps is really going sideways at best and maybe not as good as the Hattor.

The Hattor has opamps and maybe opamp rolling would improve things. I have the New Class D installed. Sound great to me, but I have not experimented with any others.

It's nice to be able to mix and match. Glad the Backert and 25s are a good combo. My heat pump is quiet with the AC mode and the Erhard just doesn't put out enough heat to bother me at all.
Title: Re: UberBuss and DigiBuss
Post by: Jack on August 13, 2026, 11:27:12 PM
Well it seems to me that since you want resolution, the Kozmo volume control and don't want to spend $5k your best bet is to stick with the combination you are using now.  As to rolling op amps the "warmest" sounding ones I am aware of are the Sparkos and were when I had a pair of amps that you could roll op amps in.  Another option is to try the Schitt tube buffer from Amazon for $119.00. If you don't like what it does then send it back.  A quality one like the one from Modwright is a whole lot more.

The resolution is quite good now and the midrange is very nice with that RCA 6ns7. I would like to get just a bit more timbre/harmonics right now. That's what I am curious about. Replacing that crappy 2' ethernet cable really opened up that element. I have been spinning my wheels a fair amount for many years in this hobby/passion. So it's nice to be able to appreciate what I have and what areas I'd like to improve. Getting your advice these last few years has been very helpful! So many thanks for that to get me to this point

I have a Khozmo with the 64 step ladder attenuator with AMRG resistors.  I replaced the Staccato op amp with a Sparkos Dual Pro op amp.  The Sparkos is considerably more open and dynamic than the Staccato.  Fast, detailed without any form of glare.  I've tried others: Burson; Orange and stacked versions of ROTM commercial versions.  The Sparkos Pro is the best I've heard so far.

Thanks for looking it up. The prices are reasonable enough that's for sure. I'm really getting good sound out of the new class D op amps. I will let the dust settle gauging the improvement with the new ethernet cable and the ultra low noise Power Supply that is coming from China. Maybe I'll try and roll some op amps after that.

Quote from: Nick B on August 20, 2026, 07:23:42 PMReceived Pete's ethernet cable this afternoon. Beautifully built and already playing. A subtle but noticeable and enjoyable improvement. It reveals more detail, is smoother, has a bit more depth on certain small venue recordings and presents the soundstage in a more realistic manner. Very glad I got it. Might be worth a try for Evan. This also confirms what a good performer that budget UPLINK ethernet from Amazon is.

I am very happy I got it and.... thanks Pete!!
:thumb:

Well, I stand by my preliminary assessment.But after 5-6 hours, things started opening up even more. Who woulda thunk it??

So I will report more tomorrow and enjoy more tunes right now 👍🎶

PS to Evan - I think you'd really enjoy the improvement

I want to finish breaking in the Uber and TWL power cord before making another change.
:thumb:
I
always live with a change for about two weeks, change back to the prior configuration and then assess the changes.  Keep what works and then move forward.

That sounds like a great method, Dave. I'd like to try this with my next cable purchase (haven't decided which one yet).

So many choices, my friend.  There's no one size fits all, because they are the final nuances in our systems.

I have some favs, though.  :thumb:

I am probably at 10 hours with Pete's ethernet cable and it's a treat. It is money well spent. I won't go into specifics as I expect it will keep evolving and improving. 

This all started when I realized I still had a 2' section of a generic ethernet cable still in place, from the TP Link to the iFi LAN iPurifier Pro optical isolation unit. That was replaced with the UPLINK ethernet from Amazon and now with the TWL.

If you have some free time and don't know what else to do, just check all your cables and make sure you don't have a cheapie piece of junk cable in as it can act as a huge bottleneck to great sound 🎶

Well I finally got around to running the Coda amp through the Majic Buss (one of Dave's originals).
I have found that through making my system better changes like this show me just about as much of what I
gain and lose through changes. It also takes longer to discern what has happened with the change.
At first I thought I had lost some of the shimmer or top end only to find what I really lost was some of the stidency
I was thinking was the music only to still hear the upper region but with a lot more lushness or fullness. It came through a lot more mellow but with more detail. The soundstage opened up quite well with more depth. I can't believe how adapt one gets with sound until you don't hear it but still hear it (only way I know how to explain it) in a different way.
Thank you Dave for the push to get me out of my archaic way of thinking and for Colin.

Which Coda amp model did you get? I ask because I came *THIS CLOSE* to buying a Coda S5.5, but veered away and bought a Shindo Montille CV391 instead. Of course, I wonder how the S5.5 would have sounded in my system.

Hey Don,

Nice to see you post. That Coda must be a sweet amp. Congrats on improving your sound.

Thanks for the kudos guys.
Being of modest means it was really frustrating trying to find an amp.
My timing was with me when I called Coda to see if just maybe they had a demo
or second hangin around. Mr. Doug Dale said it doesn't happen often but it just so happened that a gentleman
had purchased a contiuum #8 V1 and decided he wanted a 16 instead so I was able to get
it at a pretty decent price and still got a 5 year warranty. It's overkill for the Charney
Companion but is just an incredible sounding amp. Hooked up through PI Audio power cables and
tied into the wall with an Uber Puerto I am just lovin it.

An update on Pete's ethernet cable. It's breaking in beautifully and has really added to the system. It has revealed more detail and presented a more realistic presentation of what the original recording was like. I was always a bit surprised and puzzled that some of my old time recordings didn't have more instruments and accompanying vocalists in the studio. This cable dug out those details and it was a pleasant surprise to confirm those recordings from decades past were thoughtfully recorded and didn't skimp with instruments and backup singers.

Today I received a linear power supply from AliExpress. It's for the iFi optical isolation unit. Jack found it for $60 and Dave confirmed it was a quality lps. The shipping was less than $25 and the seller was great to deal with. I was going to keep it out of the system, but a little bird on my shoulder told me to put it in. It's easy enough to go back to the wall wart. Just change the USB C wire plugged into the iFi. Everything is, of course, plugged into the Uber. I only have a couple of hours on it. But all that new detail revealed by the ethernet cable has been refined and presented as a naturally coherent part of the recording.

So my thanks to Pete, Dave and Jack 🎶

It seems like this experiment has reached a succesful conclusion. If you're still looking for more tone and timbre then that's going to have to come from somewhere else with possibly an equipment change or modification. The VG's are always going to tell the truth about what's in the chain in front of them.

Yes, a wonderful result. The VGs are a special speaker. Your recommendation on the little brother Abscisse and them then being received damaged led me to the path of the Voce Grande. A circuitous route, but I'll take it!

You are welcome from us all, I'm sure.  It's what we do.

The best thing any of us can do for SQ is getting power right.  A bad heart pumping diseased blood ain't a good thing.  The brain has to think clearly.

Getting every SMPS power supply out of your system is a good thing.  Getting every SMPS power supply off of your AC branch circuit is equally important.  There are 2 branch circuits (phases) in our 120VAC power.  Get all of the audio on one branch and every SMPS on the opposite branch.  The ground is shared between them and is a source of noise and distortion, but this is easily handled.

Thanks for the information. The only SMPS at all connected now with my Audio system is the TP link router in the adjacent room that receives the direct wired connection from the garage. I have certainly thought about using a good quality linear power supply for that unit as well. But then I was thinking how much could I gain because the data is streamed wirelessly from that main TP link unit in the bedroom to the TP link unit in the living room where my audio system is. But frankly I wasn't expecting much of an improvement with the AliExpress lps for the iFi and it blew my socks off. So what the heck do I know  😝

Is the breaker in your bedroom where the SMPS is located on the same phase in the breaker box as the breaker you system is on? If it's on the other phase it should be fine.

That's a good question and I don't know the answer. My handyman is pretty sharp, but this is better discussed with an electrician. You will remember the last time I had an electrician out here to discuss a dedicated AC line, I wasn't confident in his ability.

Look inside the breaker box and tell us what number the breaker for the two circuits are on and we can tell you.If they are not correctly labled you might have to flip some breakers to determine it.

Just looked at the breaker box. The master bedroom, where the wired TP link unit is, is on one side of the panel and the living room is on the other side.
