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

Hey Gaslover! I haven't heard a Grandson yet, but I've acquired four Sons, an AmpzillaII, and a Gas 500. I've had them all recapped and gone over, with two of the Sons bridged. They are all fabulous, but the amp that knocks my socks off is, believe it or not, the Leach Low TIM amp. I found a pair of original LSR&D "Superamps" on Craigslist, had them redone and they beat the Ampzillas hands down. Speed, detail, linearity, but above all, truly flat response equate to extremely fine and precise transients. They simply display the particular recording you're listening to.

I've been through quite a few power amps in my lifetime up to about $12K, but it looks like the Mingda MC300845AB monoblocs (about $5K) are keepers. These are 76kg push-pull Class A tube amps producing about 90w/ch, a pair of 845B output tubes driven by TJ 300B meshplates in turn driven by a 6SN7 ...great line up of tubes and great sound!

These amps appear to be able to drive almost any speaker, have a thumping tight bass, a clear and lucid midrange, a sweet tinkly treble, high on transparency and unusual for a valve amp sound extremely clean with none of that mushy overhang to musical notes.

The Mingda 845 amp is a great match with my Supratek Grange preamp, which is also a keeper.

Pass Labs Aleph 30 will never leave.

Aleph 30 is a great amp. I was bummed that it had too high a damping factor for my speaks.

try a mc cormack or plinius for solid state or a vac for tube
