Need Wood Vibration Control Cones!!!!!!!!!

[Barry (NJ)]

I've got a neat little isolation system that Dave had given me a few years back. It consists of 3 rubber balls and 3 cups for them to rest in. The balls can roll a bit in the cups, but they do "Center" themselves. Let me know if you're interested, and we can figure out how to get them to you.

Hi Barry,

I'd love to get hold of them.  Tweaks like this is easier and more fun.....

I have to deliver 2 issues of a HK Audio magazine to Karl (Bedminster).  I resisted to spend the $12 (!) toll until I have a more productive trip crossing the GW.  Now, I have a good reason to do that.  I should now make a trip to drop by your place, then his.... or vice versa.

Let's arrange a convenient time.  I am aware of the "cup" kind of setup.  The Vibrapod people recommend using their cones with their flat/cups, but I just was taken aback by the lousy sound of the flat ones.  A friend told me that Vibrapods or plastics they suck....  So far, I'm better of without Vibrapods....

Shek

Well if you were taking the trip during the day on a M-F I can bring them with me to work, right off 95 in Teaneck Or I'm home most evenings and weekends

shek,
Don't forget the wood.

I have a feeling wood might work best with the microphonic DHT 26 tube. A soft wood.

I have a phono pre that uses semi circles made of wood for feet.

But I think the microphonics are just going to be something you have to live with. Buy lots of 26 tubes on ebay, you may find a quiet pair. Microphonics are a small price to pay for the sound of a great sounding DHT tube, or try the 6c45pi tube!

Yes Signore, I am "living" with the microphonics, but just am "tweaking" it where I can.  Someone from Canada just also advised me to "loosen" (somewhat) the screws on the chassis.... that should help, he said.  will see.

Another friend just showed me how to make my own Herbie's, O Rings and washers from Home Depot..... 

The sound of the 26 pre is wonderful, guys.  I guess because of the microphonics issue, nobody really put money on it.  Now, at least within my circle, we became aware of it, and benefiting from the fantastic soundstage and presentation.  I haven't heard as many amps and preamps as you guys.  But, for what I know, this IS the best.

Thanks.

May be this coming Sunday I can come around to your place, then Karl's or Peter's to drop off a couple of magzines for Karl....  What's the better/best time Sunday?  Thanks.

Can't fight City Hall syndrome now.  I'm going to live with the microphonics "as is", since it's somewhat stable situation as long as I don't tap/rock the platform/chassis.  

I've played with "doctoring" the sound quality.  In the end, I think I like it "as is" also, without any Vibrapods, etc., underneath.  The Vibrapods killed the sound quality IMO.  The foam was slightly better, but.... still the sound didn't thrill.  Also, I came across some ceramic door handles/knobs the other day.  I took out the screws, and stuck them underneath the amp.  Believe it or not, the sound was pretty good.  Shiny, punchy.... But, I still found it not that musical to my taste.  If you twist my arm and choose I'd take the ceramic door handles/knobs.

WITHOUT anything, the sound is actually MORE organic, more musical to my taste.  I was told that wood may be THE answer.  I'm trying to get someone to "make" some Ebony cones for me.

NO Herbies.  They're too pricey.  I actually bought some parts from Home Depot, see if I can make something similar, O Rings and Washers, from the Plumbing department.  Didn't go through with it.  I am staying with the teflon tube dampers from eBay.  Cheap enough.

All in all, without anything underneath, the sound is more preferred.  Is this what they "the more they change, the more they don't change..."?

It makes sense that different footer will effect the sound but have no effect on the airborne microphonics.  If you get a chance find something, anything, that will cover the tubes. Do you have an aquarium laying around the house that will cover the preamp? Cardboard tube?  Anything just to experiment. You will be amazed of what this will do to control airborne vibrations from getting into the glass with no ill effects (no effects at all) on sonics. If you find that works, then you can seek out a permanent, more feasible solution such as an acrylic cover for the tubes.
Don't waste your time trying to put stuff on the tubes or under the chassis to control the airborne stuff.
Just my 2 cents (or is it $2 these days)

Thanks Bill.  That certainly is worth trying.  Shouldn't be too painful.  I will look for something to cover it up.  Only thing otherwise thinking is that I'll probably make some "holes" for ventilation..... since the GZ34 gives off much heat (most of the heat for this pre).

'Nuf playing with footers underneath.  So far, not impressed with foam, Vibrapod, ceramic spikes, or granite tiles (they all SUCK!).  WITHOUT anything underneath, the pre sounds best, most musical, warm.... more lower frequencies.  A friend told me wood'd the best.  So, I'm waiting for another friend to make me some Ebony wood cones.  Microphonics are tolerable, but WILL look into covering it up on top.

Chapter closed!

 I took out the screws, and stuck them underneath the amp.  Believe it or not, the sound was pretty good.

What did it do for the Microphonics? If you like that sound do it to your source if it's digital. This works better for sound.

What you got (in order) is the source bottled up, the preamp released and the amp bottled up. Take the tension off the source or amp too. Preferable the source. then do the amp after awhile if you like.

Then release all the screws in your outlets. Electricity is vibration. You heard the preamp released so you know it's not fake. Whether you like it
or not is up to you.

we all have a loose screw!

You need at least a 1000 posts to get the "loose screw" designation here.
