I think from memory they are Conrad Johnson Premier 12 tube mono blocks. Perhaps @MattHooper can clarify this for us and give us the model number?Which one is that? I'd like to know.![]()

Those are the best ever made? Huh.
That is the weird and inconsistent part. I've never heard an SET that didn't create a caricature of sound of the source recording. I've listened to push-pull triodes and liked them despite their shortcomings. I'm not trying to insult anyone's opinion on what they like, just describing that it varies.I do not know the Conrad Johnson, but for many years I prefer only SET anyway today. My last more push-pull amps were the ELV 100 (picture) about 20 years ago and a Line Magnetic LM-211IA until last year. Both I found sonically boring. No trace of the sonic charm of a tube. In comparison with these I prefer then my Yamaha SS amps.

Tube amps used to be good measuring, back in the day. It's only lately we've realized they should really be distortion boxes.
Good to hear. I like them.Same reason modern Corvettes, Cameros, Mustang's , Challengers, etc are so successful.
This isn't 1969 any more.
If you were my neighbor, I'd say you can come over and we'll listen and chat a bit. Provided you like classical music.I've never heard an SET that didn't create a caricature of sound
No; but Ralph's OTLs from Atmasphere measure pretty well, last I checked. So it can be done.Does anybody have sound experience with Futterman tube power amps which have no output transformer?
Yes. They can be pretty clean, but in the incarnations I've used lack oomph when push comes to shove. With an efficient enough speaker not a problem.Does anybody have sound experience with Futterman tube power amps which have no output transformer?
I do like classical and would gladly come listen if we were close enough.If you were my neighbor, I'd say you can come over and we'll listen and chat a bit. Provided you like classical music.
I've always had a lot of fun and a sense of accomplishment at meetings like this.
The McIntosh amp always reminds me a bit of Harley Davidson in appearance. I can't make friends with that.
I don't know why these people refer to us this way. It looks so unprofessional. Just say the site name as we are doing here with stereophile.
Yes. Paired well with the Quad 57s I had at the time. It was an idiosyncratic circuit, and I suspect that Atmasphere's are quite a bit better.Does anybody have sound experience with Futterman tube power amps which have no output transformer?
Well, beauty is in the eye of the beholder. I wouldn't let it in the house![]()
My experience with audible vacuum tube microphonics are that they are usually high Q, resonating for a few relatively narrow frequency band stimuli.should the frequency dependent crosstalk in a tube system follow the load curve? Or could microphonics add reverb?
Yes. Decent sound, still not super-low output impedance so load-sensitive, pretty much every amp was a little different, and reliability was not spectacular. As others have said, the torch-bearer for OTL tube amps today is Atmas-Sphere AFAIK and Ralph @atmasphere is a member here.Does anybody have sound experience with Futterman tube power amps which have no output transformer?
They were in a famous blind test:Does anybody have sound experience with Futterman tube power amps which have no output transformer?
All-time famous test. Many in this thread should read, would save 18 or more pages of nonsense...
Yes, back in the day, with KLH model 9s, which I very much wanted to own.Futterman tube power amps
