40+ watts SET, cost is not a problem


Hope everyone is well here. I am visiting after a long time. I have a query on behalf of a close buddy of mine. He is using a pair of TAD CR1x loudspeakers. Gorgeous speakers for sure. The source is an EMT 927 TT & JPA66 preamp. For the amplification things are getting tricky. He has tried the TAD M700s reference power amp and while it sounds very controlled, it doesn't have the openness and dimensionality of tone that a good tube/SET amp provides. We are considering trying a good SET for this system. Given that TAD needs some power blossom well and expand on effortlessly, at least 40 watts of SET power would be needed. The quick choices are Kondo Kagura & Wavac HE833 Mk2. But I need more suggestions on these and other comparative products.

1. Has anyone heard the Kondo and Wavac gears to suggest a comparison? I am just a bit worried on the amount of Silver used in Kondo. I have normally found that silver takes away something from the flow and harmonics. Tell me more about it.

2. What other options can be considered in this realm? No SS please. Looking for SET options primarily.


Room size is moderate 17 x 13 feet. Music preferred are classic rock, jazz, pop and some classical



I am personally a big fan of a well designed Class A triode wired pushpull amp using a variety of tubes, EL34, KT77, KT66, 6L6, 5881. And I agree those aren't good speakers for an SET amp.

@audioman58 , this is someof what Cary says about the 805Rs:

the tube complement,per monoblock is


2 - 6SN7 input tubes
1 - 300B driver tube
1 - 845 output tube or (Please choose 845 or 211 during install)
1 - 211 output tube (Please choose 211 or 845 during install)


Circuit Type Single-Ended Pure Class A
Power Output 50 Watts Pure Class A

@jond Yep…..but like in most things… transformers matter… Roger Modjeski wound them himself.

@atmasphere Ralph… zero nfb glad to hear you utter those words…. ha.

@atmasphere @charles1dad @jond and others, it seems people are not warming up to the idea of SET here. And also there seems to be very few seriously good tried and tested choices beyond 25 watts. So what are some really good options for push-pull tube amps operating in class A with zero negative feedback?
