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

Stephenss,
You didn't say what kind of amp you have!

Well, I am hoping that my CODA 15.0 lasts me the rest of my life. I don't feel as if it is lacking in any area. I am exceedingly pleased with it and have no plans of looking further.

I Just bought a pair of LAMM M1.2 Reference monoblocks which have replaced my ARC Ref 210 monoblocks. The LAMMs leave the audio research amps for dead. I have also heard the Ref 5 SE / Ref 250 combo and again the LAMMs are clear winners. I have never heard an amp which sounds so realistic. I will be keeping these amps for a long time ( or until the next stroke of genius from Vladimir Lamm).

Spectron Musician III MKII with Bybess and Vcaps.

At the lower end of the price range, I would say the old classic Audiolab 8000A.

In the middle, I would nominate the Naim SuperNait.

At the upper end of the scale, my vote goes to any Accuphase Class A amp, starting with the E-560 integrated.
