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

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.

Currently own four different power amps, modified versions of the adcom 555II, hafler dh220, rotel 951mkII, and Will Vincent st-70. Have owned several carver amps, a mac integrated, auditioned a mc2200 and bryston 3b in my current system. When it comes to vocal reproduction and soundstage nothing to date beats the st-70 in my system. The moded 951mkII comes in second, nice soundstage with the vocals a notch or two behind the st-70. The moded 555II is a power house no doubt but is very two dimensional and weak in the vocals. Much to my amazement the mac 2200 and bryston 3b were the worst both brittle in the top end and flat in the bass! Before the mods the little 951mkII was not listenable imho, replaced the filter caps with nichicon ones and all circuit board caps with elna silmic II's. Big difference, stock caps were terrible. I'll keep the st-70 and 951MkII for some time but can't say the same for the others.
