Good SET Tube Amp for $1500?

I would suggest you to build one! Welborne labs is offering a new KIT in pair of monoblocks DRD 8wpc (300B)! And also there is a "Billie".

Audio note Kit One is my choice......

Wright 2A3 monos should be in your ballpark and are exremely good. The ASL Tulip is also very good and is less money. I personally prefer the 2A3 tube to the 300B, but you do have significantly less power. I suggest these because you asked for "low power set". If you are willing to try push-pull tubes I can heartily recommend Quicksilver mini-monos. They are definitely in your budget new and can be had very inexpensively used. 25 watts per channel, very reliable, and close to set sound.

Rogerroger- I'd agree the Mini-Mites are great little amps and sound wonderful, but since I have both a pair of those and Quicksilver 300B SET amps I can tell you with great assurance that the sound of the two (at least with that specific SET) are quite distinctly different. With my limited audio vocabulary I would say that SET gives much more of a sense of airiness and spacial qualities than the MM's do. The sounds linger in the air as they fade off with SET....more musical in that regard. The Mini-Mites have more of a punchy sound to them which is well suited for more dynamic music, but ultimately they do not have the same holographic sound as SET. Fabulous soundstage though, so don't get me wrong! Absolutely agree, great little amps, but not the same as SET. I'd also agree regarding George Wrights 2A3's but they'd really demand an efficient speaker to make them shine. Don't know how efficient those Soliloquy 3.5's are, but with those Wright 2A3's in a moderate size room I'd look for something at least in the mid to high 90's if you like listening to things at more realistic volume levels. Horns would be heavenly IMO.

.02 cents more for your consideration.

Best,

Marco
