Obviously design of an amp is important. FWIW, the AG amp is not Class A. I thought that the new AudioPax Majjore amps are parallel SET where each tube can be biased individually for sound tailoring.
I think you need to explain what you mean here with regard to "SS badly" and "edge is taken care of". How do they take care of the edge? How are they listening to SS badly? it is really unclear here what listeners are supposedly doing wrong and how that is taken care based on your somewhat vague comments.
My point was, for those who don't like the duos, even duetta driven by a Parasound sounds better - nothing fancy required.
Sorry, I have listened to the Duetta II's with an Electrocompaniet AW250 sounding great ... I have owned until recently an old AW250 and currently host a Parasound HCA3500. I really prefer the Electrocompaniet sound, surely YMMV.
BTW, this thread is missing my preferred type of amplifier - the high power, high quality tube push pull, such as the conrad johnson LP275m or the Audio Research REF750. Or the high power OTL - such as the Atmasphere MA2.
Much easier to hear SS distortion than tube, hence why I found the test so interesting. Have you ever tested a low power SS amp? The SIT monoblocks had more headroom, despite same wattage fyi.
What peaks were you seeing on the Mac 501s? I had 601s and saw 6 watt peaks often during music passages. Very good amps on my 101db Zus. In fact, my Audion SET friend (Golden Dreams and Black Shadows) only recommends Mac quad balanced amps for SS on Zu speakers in general. My guess is the Macs didn't like the 2ohm loads of the Thiels, as an amp without autoformers (Jim used Krell) works better.
But I'm simply suggesting Thiel is not an ideal match with SET because of higher distortion w/ power, while actual power is considerably lower than spec bc of Thiel's lower impedance. Seems like compromise 101.
The SIT monoblocks had more headroom, despite same wattage fyi.
More wattage than what? The stereo SIT? Or a tube SET? Where did you see the dynamic headroom of the amp measured? Just would like to see that data.
Well, suggest what you want, I have plenty of proof that it works rather well, with at least 4 different SETs. So well, in fact, that this friend sold his MC501s and eventually went SET. Most of the time the power was cruising around 1 watt or less but peaks could be as high as 20-50 watts when we had it cranked up a bit. Funny thing about distortion increasing with power...your hearing gets less sensitive to distortion the louder it gets. This means a SET is performing best when it counts the most and worst when it matters the least...at least with decent sensitivity speakers. The problem with a lot of other amps is that the distortion % is either constant or increasing as the power goes DOWN (at least until clipping). Also the harmonics are of higher order content, which is less well masked by the ear/brain and are therefore MORE audible at low listening levels. This is harmful to the realism of the sound on many levels.

Umm...ok if you liked it I can't say you didn't. However, I and nearly all my Apogee friends dumped big SS amps for either hybrids or SETs. OTLs can sound really good on them as well. I once had Silvaweld OTL reference monos...they sounded great when they could hold their bias. But having 4 x 6C33C per mono was too much trouble and too much heat. They drove the hell out of electrostats as well. I also had a pair briefly of Transcenent Sound "Beast" OTLs that I built myself. They didn't drive electrostats at all...they oscillated like hell once you put any power into the speaker. Sounded great on conventional speakers though... As to big Push/pull tubes? I have only heard the two that I thought I would like to own...one is the CAT JL2 Signature and the other is the Jadis Defy 7 III. Nothing I have heard from VTL, AUdio Research, Octave etc. has convinced me (in fact I think top notch hybrids sound better like Ypsilon).
Another Class of amp that is very good, nearly SET good, is the Class A push/pull triode amp (THe CAT actually falls in this category). A VAC PHI 70 or Antique Sound Lab Cadenza DT would also tackle tough speakers with relative ease and convincing sound.
I have heard Electrocompaniet get SPANKED in two different systems by a KR Audio VA350i. One system was the Acapella Violon in a moderately large room. Despite have a horn mid and a horn loaded plasma tweeter, the overall sensitivity of that system is only about 92db/watt. It destroyed the AW250 in everything...including bass power and control...it was an ugly defeat. And that was even feeding both with an Ayre K-1x preamp. The other was the Focal Grande Utopia Be EM (the electromagnetic damping bass...pretty cool) against the Nemo amps. Again, it wasn't close and the KR drove that 94db/watt Focal with ease and power in a relatively large room.
Maybe it drove the Duetta II, ok, it is a pretty resistive load...but it also one of the darker sounding Apogees...the Duetta Signature was a better balanced speaker. No offense to John Curl but I haven't heard a good sounding Parasound yet.
Morricab,
Just to check for other options . I have KR tubes in my Lampi and if I only have the opportunity to audition their SET amps I will give them a listen.
We have briefly compared the KR VA350i to the Crossfire III and while the character is not exactly the same they are at comparable sound quality. The VA 680i should be better.
Most interesting...I have done a little bit of reading about Ayon. Your comments and Morriscab's have me intrigued. Having heard Avantgarde only a little, my gut tells me i would also like to hear them with high quality tubes as Ayon seems to design as well. Given your location, are you able to hear Gryphon by any chance? I have not heard Karan, so cannot say if they are similar or not. Just curious as to any impressions you have about other SS with your speakers. thanks.
Also curious if you have heard Ayon's other amps...they seem to make a few other models that continue to go higher and higher in SOTA.
Listened to Stravinsky Petruschka and Rite of Spring today on Decca (Riccardo Chailly, Royal Concertgebouw) and it was fantastic with the Ayon. My room and speaker spacing does not allow the full width of space that one would get live, but depth and most importantly instrument separation were superb even when it got busy but when it was quiet what struck me most were two things:; 1) the tone and sense of space around individual instruments: flute, Oboe, piano, bassoon, Trompets etc. They had quite believeable tone and dynamic contrasts. The second was the bass...the Ayon gives my Odeons real heft and at the same time superb control. With the big bass drum you could easily hear the mallett impact followed by a big round Boom that stopped sometimes slowly and sometimes quickly (I am assuming that the percussionist was damping it at times). Finally, the Tympani drums have never been clearer or more well defined in the evolution from impact to decay. The tone was full an textured...I was loving it each time they were struck because it was a very much like I hear live. Now this is a great recording and with lesser recordings all this details gets to greater or lesser degrees lost in the mix. I have some Tchaikovsky recordings on Decca that also deliver this kind of impact and resolution and my system handles them quite well but with the same caveats noted above. Chamber music though can sound quite realistic in most respects.
Sorry I did not answer.
Last 3 days I was very busy because of Audio Video Show in Warsaw and also because of my second granddaughter's baptism.
Will try to share my thoughts within a few days but Morricab did already a great job

Congrats and thank you!
You should have come ...
When I first booked in to cover AVS 2016, I had no idea what to expect from it. Now that I’ve been there and done that, I can say with confidence that Poland’s Audio Video Show is poised to become one of the largest and most influential hi-fi events in the world. It has great organization, and insofar as the National Stadium goes, an incredible location. Come in 2017 and see if you agree. I think we’re coming back with a bigger team!

This is the first Warsaw that we at Hifi Pig have attended but we’re so happy we made the effort because it has been undoubtedly one of the best, if not THE best we’ve been to. The people of Warsaw have been wonderfully welcoming, the food and drink has been spectacularly good and the company we’ve enjoyed has been marvellous.
