>>>>>Can you share your amp evolution with the Abby's?<<<<Well the day I got them, I didn't like the way they sounded when I hooked them up to my normal 300b amps. I knew I was in for a problem.
I got out a pair of 811's which have a little more power and are equipped with st-70 opt's. They sounded the best of a few I tried. But being I'm a fanatic about the webster opt's, I was not happy. So I hooked up an 845 with websters and lived with that for a while. It at least had the emotional impact, the engaging sound that I crave, but otherwise didn't sound the best.
Then I picked up a 45 I had with websters and it sounded better than the 845. It is a 6sL7/45 and I used a 6sn7 linestage to give it good power for the abbys. Actually surprised the 45 works well.
But I had used a 27/2a3 along the way too, without websters, and it picked up rhythm better. I thought at first it was the 2a3 tube, then thought it was the 27 tube. (I now believe it is the circuit).
So the idea was that I wanted to have the best of both amps. One played jazz the best, but didn't pick up the rhythm in the music as well as the other. The latter, even without websters has a certain riveting quality to it.
So I asked John to build me a pair of 6sn7/27/45 monos. But he wasn't in the mood at that moment to build a two stage driver, so he built me a pair of 6sn7/45 webster monos. They sounded good and I was using them. But I still wasn't really thrilled.
Then John finally built a 27/45 webster on one chassis and I used the 6sn7 linestage as a prestage driver for it. When I hooked that up to the abbys, I knew I finally reached it with the abbys. Not only the best amp, but now a sound that just rivets you. The combo just has a awesome sound. Best sound for jazz I ever heard. Such an open sound.
I'm sure you got more information than you needed.
I'm sure Terry Cain has access to innumerable high quality amps. But I will be presumptious and say that this amp will beat anything he's ever heard with his own speakers. :)

The amps shown have hg rectification which to me puts them in their own league. I get people railing on these as "not the best sound" all the time, just "looks". I just have yet to hear it. They do hum a wee bit more but no 3 or 300 watt amp quite does what these do. Very similar circuitry only the first driver stage of your 6sn7/27/45 I use a 10y/801/45. In my well treated room at the shop I have 2ft thick walls and is all wooden. The big problem I have listening to Abby's is I usually only have newer ones and they're never broken in. Someone always gets my personal pair.

> > > > > 10y/801/45 < < < < < <Hmmm, that sounds interesting.
If you are at the stereophile show coming up in New York in may, maybe I'll get a chance to hear other amps with the abbys. But I think ahead of time I got everything beat. I'd like to hear the bens too.
Now that my nearfield abbys are broken in, it's an incredible sound. It really is, I'm not just saying that. I guess the single driver folks really invented something with this voight pipe(?), and your fine wood construction really took it to another level perhaps. It makes me really love the 45 sound.
If I had the extra money, I would consider a second pair and replace something else with them.
