Amplifiers:A Keeper for Life. Do you know of one ?

I've been using (and enjoying) my Classe Audio DR-15 for over twenty years. I finally broke down and bought a demo Mac 275, Mk 6. When I picked it up, it was a brand new, factory-sealed unit. I plan to use it with a pair of Quads. All I need now are the speakers!

Edge NL 12.1 in use for about 7 years now. Great power with hard to beat sound. Compared with a lot of amps initially and this consistently came out on top. Using with Edge Signature 1.1SE pre and Allnic H3000 tube pre.

My Crayon CFA-1.2

I have ~ 200 hrs on the new CJ MF2550-SE and don't see ever upgrading. I love this amp.

Recently picked up a Threshold S/300 to drive the top end of my Infinities. Very nice amp I think I'll keep it. Once I get my VTLs, LOL, I'll use it for the bass towers.
