Quote from: Response Audio on June 22, 2025, 08:52:07 AMAll preamps have remote volume. The 2A3 preamp above is my original prototype and the remote volume is not hooked up.
The Master Series will use autoformer attenuators.

A great idea to have remote control and an absolute necessity if you do streaming with all the volume fluctuations. The first time I ever heard of an autoformer was with the Bent products.

We used Bent Audios autoformers for years. In fact build a Purity Reference preamp right now with Johns products.

We are currently working on the Master Series chassis. Quite a bit going into these and will start out the......

Our Master SET amplifiers and DHT preamplifiers will be housed in new custom machined aluminum chassis.

We will keep the Foundation and Spirito 2A3 linestage in custom, but simpler chassis. That's why we're trying to clear out our current inventory allowing for customization.

Bella Extreme 100 mono bloc amps. Price drop to $3,400 with power tubes or $2,900 without tubes.
I am holding on to the second pair for personal reasons. I like them far to much to not have a pair around.

Just curious, Bill. Do any of your products have remote control or do you prefer the simpler, purist approach?

By the way Nick, the autoformers we will be using in our new preamps will come from the same person that designed you Hattor (Khozmo).

Bill, that's really good news. Arek builds quality products and his remote is the best I've ever used.

Great quality at reasonable prices from Arek!  :thumb: The 64 step attenuator in my Khozmo is very, very good.

Still have 2 remaining chassis that can house the following builds:
- Foundation v3 preamp $2,695
- Harmonia 45/2A3/300B output stage for source components - $2,995 (single ended)
- MB300H Hybrid GaN FET 300 watt stereo amplifier. $2,995

- Spirito 2A3 Linestage - we are on our final days of the introductory price of $2,995

Interested parties, please feel free to contact me with any questions you may have.

Bill,

I am curious about the MB300H amp. Years ago I was very interested in (but couldn't afford) the Butler Monad monos. The design intrigued me a lot. So I am curious if your design might have some similarities to BK Butler's. There was a guy on AC years ago who owned a pair. I have never owned a 300b amp.300b sound and GaN power is such an alluring combination.

Hi Nick. The MB300 uses our 12AU7-12AT7 circuit feeding the 300 watt GaN FET. My preference is the Spirito 2A3 linestage feeding it so the get the best of both worlds and the versatility of separates. We also have a 300B preamp coming.
The MB300H and 2A3 linestage will be my personal summer setup.
What Butler did uses a very different topology. I've heard these amps a few times but it has been a while.
I can't say they similar sounds.

I appreciate your response, Bill. I have very limited experience with tubes only having used Supratek and Audio Hungary preamps and VAC 90 monos and RM 9 amps. I will do a little bit of reading on the 12AU7-12AT7 tubes.

Great quality at reasonable prices from Arek!  :thumb: The 64 step attenuator in my Khozmo is very, very good.
Hi Dave, are you still making power conditioners these days?  See your PM's please when you get a chance.  Thanks.

Every once in a while, an UberBUSS or similar product from Dave will show up for sale. I check HiFiShark.com first as they collect info from other audio sites.
Good luck. I love my UberBUSS...
