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

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

I'm not giving up my Spectral DMA50 any time soon, and I'm always on the look out for another as spare or for bridging.
I've had a Luxman M12 since new, and it's not going anywhere either. I just got a pair of B12s (mono versions of the 12), and if they prove as musical & reliable, then I'll have another "amp life partner".
