Amps which are Great, but either Unknown or Underpriced

Nelson Pass Forte Audio.

Yes the OP asked for less expensive even vague yet people continue to drop some of the biggest names out there. 

My view is that unless you are a dealer/salesperson trading frequently makes your "budget steal" anything but.  I perfer to buy something quite good and enjoy it, and stop reading audiophile-nervosa publications.

In 1982 I bought a used Threshold Stasis 3 for $1100.
In 2000 I sold it for $800 and bought a used Pass Aleph 3 for $1200.
In 2003 I sold that for $850 and bought a used Pass X-150 for $1200 which I still use daily.
I'm toying with buying a used SIT now, if so, I'll get my money back on the X-150 - which is a superb amp BTW.  The Aleph was just too short on the current.

I was a salesperson at one point with good connections to several dealers (still), and also during these years briefly owned products from: Blue Circle, Classe, Krell, Dynaco VI, Bedini, Hafler, ARC, CJ, and many more which I usually got my money back, or made a few bucks on, never having unseated my current Pass amp. 

So, be sure of your speakers, then source the best bang for the buck amp (probably used) that will handle them, and enjoy the music for years - that's the best way to get a "deal".

Let's talk preamps - I had a used ARC SP-15 for many years which I had for years and got pretty much my money back.  I replaced it with used Pass P and XONO pair about 13 years ago. No need to fuss with that pair either.

Dayens Ampino, the little amp that could!

hi ,
does anyone know of lesser known hybrid amps? i done some research but only a handful of names such as Van Alstine, Aesthetix, Union Research, BlueCircle, JE Audio, Monarchy Audio, Moscode, Vincent, Pathos, and Butler audio.... so that's about it ?! And one last great hybrid is from tube distinction (Soulmate)but already defunct. 
btw, please keep chinese brands out of this list. 
Thanks in advance.
