SET amps

There is an audiophile who keeps a blog called Glow in the Dark Audio. He has written reviews of many different affordable set amps. You might want to check it out. http://www.glowinthedarkaudio.com/amps.html

Thankyou Riley mentioned the site and it’s been helpful.

Make sure you have speakers of sufficient efficiency! If you really want to get the most out of your amp, the speaker should be sufficiently efficient such that the amp is never pushed past 20-25% of full power. This will allow the distortion of the amp to be very low; the source of their 'inner detail'.

Easy Decware!

I think the best value vs. sound at your budget can be had from Transcendent Sound. Most of his amp kits are OTLs but he also has a push-pull KT120 that I think sounds very good. The owner/designer is a bit full of himself and his soft skills suck but his stuff sounds better than it should at the prices charge. See what atmasphere says above about SETs. I found this to be exactly true with 8 ohm 96 db efficient speakers.
