40+ watts SET, cost is not a problem

I have not heard the new WE amp myself.  But, an old-school Western Electric fan who knows a lot about amps did hear it and thought it sounded quite bad.  You must hear it for yourself. 

As for non-SET alternatives, I mentioned the Italian brand Synthesis.  I have no idea about the specific topology, but, I do think that they sound good.  At a local dealership, a shockingly expensive array of amps have been traded in favor of much cheaper Synthesis amps, including Jadis and Audio Note amps that cost more than twice the price.  There are custom builders that probably can make something that would fit your requirements, such as Aric Audio and Don Sachs.

Although some Atmasphere output transformerless (OTL) amps are voice a little bit leaner than my personal preference, they make wonderful sounding amps--extremely lively and immediate sounding without being harsh or analytical.  I liked the MA-2 model I heard.  But, because they don't have output transformers, they tend to have a high source impedance that may not work well with low impedance speakers so you should consult with them.  Every serious listener should at least experience the sound of a good OTL amp even if they don't ultimately fit one's bill.

@brandonwade ,

I think you could have gotten your point across without swearing like that.

Yes, I find it offensive, crude, unnecessary, devaluing to your point and also against forum rules.

Audio Mirror / 45 watt single ended monoblocks using 2x 6c33 per block.
Used can be found for $2 - 3K. Good used value, sound fantastic and great customer service from Vlad.

Hey there, my name is Brandon Wade and I am the owner of Apollo Audio Systems, a Seattle based SET amplifier company and think I could offer some choices in higher output units. We are currently in development of 30w 211 ($6k per pair), 50w 810 ($14k per pair) and 88w 833a ($30k per pair)SET monos with the first of the 833a units built and ready for production, the 810 on the bench right now for the final massaging, and the 211 coming soon. Our goal at Apollo is to get fine SET gear into the hands of those who may not have been able to find them approachable due to both affordability and output power. For those who struggle to get full bandwidth response I say, that's too bad for you. Not a problem for us. Our -3db points often hover around 8hz and 22khz, full bandwidth power. Just about anyone can make a decent amp, not many can make them extended and refined. Another advantage of our amps is the way that distortion is delivered. The curve is exponential and starts ramping very close to clipping, this means that it stays low until your are really pushing them close to clip. This is MUCH better than about 95% of amps we've ever tested. I currently use our 20w 811a monos on Tekton Ulfberhts and it's enough to play me out of the room. If I move to any the larger models it's pretty over the top. I hand build each amp, offer custom powder coat and accent options for integration with our chassis or just to stand out, VCap coupling caps, Alpha silver clad point to point wiring, limited lifetime warranty and optional NOS tube compliments. I hand deliver and set up the 50w and 88w units for you as well. Images of the aesthetic of our devices can be found on our website. SET, for me, is just what my ears want to hear, it's why I changed my entire career path haha. I've owned Bel Canto, TONS of bottlehead, NAT, custom SET builds, and now our Apollo line. I listen to Apollo now. I love to talk about this stuff so let me know if any of this is sounding interesting to you and we can start a build to your specs. Thanks for your consideration.
