Which Integrated tube amp?

Rogue Audio Cronus................For my ears, within my system and musical tastes, and in my room...........It's perfect.

Conrad Johnson CAV50 one the best and classic EL34 based designs, with proprietary CJ caps and built to last.

Oh yeah it sounds magical.

I had a Cronus that I purchased new from a local dealer and the CJ that I purchased second hand on the 'gon is a considerably better sounding amp.

At the $3K price point I'm inclined to suggest what I know best: a Cary SLI-80 with a compliment of NOS tubes.

There are a couple of good threads on AgoN on the subject of tube rolling the Cary. Something they don't mention are the new production Genalex Gold Lion KT-88s. They are highly recommend for the Cary.

A used SLI-80, a full set of good NOS tubes and Genalexs will bring you in just under budget.
