Remarkable thread, at least as far as I am concerned . . .
I happened upon the AM-7040 amplifier and matching AP-7020 preamp, both boxed with papers in NOS condition.
Have had them for a few years, and they are a remarkable addition to my listening systems.
Since I have about 7 or 8 systems at my home in Florida, the Sherwoods get time only now and then.
Recently, I located a Sony C339ES cd player, which I now use with the Sherwood system, and a Sanyo Plus Series, T55 tuner as well. Not a perfect match color wise, even though all pieces are black(ish).
Sonically, however, the Sherwood amp and preamp are extremely high end. It's not just the 200 wpc output, it's how well that power is sent to the speakers.
I was toying with the idea of a tube preamp to use with the amp, and was looking at Dared and Meixing, but have not made the tube commitment yet. Still open to suggestions.
The Sherwood pieces are under the radar, most people don't even know Sherwood made some really grand pieces.
BTW, when I switch on the AM-7040, the lights in the house momentarily dim.
Cheers
