A Technics is a step above a Panasonic or Matsushita.
that's the difference.
they are good amps for the price, but they are no Pioneer, Kenwood, Sansui, Sony, or Yamaha- those high end amps have much bigger power supplies, caps, heatsinks, and are much heavier- some can be had for the same prices or slightly more, than an MCS now.
I only paid $50 for a Pioneer SX-1250, it's all luck of the draw. I paid $10 for a really nice Kenwood- both are superior to an MCS. I paid only $100 for an original owner Marantz 2270, and $100 for a Fisher tube 500 C- both from the same original owner.
if it's made by Panasonic, I don't really seek it out, or want it.
there's really no reason to go on an MCS buying bender, they are not a diamond in the rough, they're just a decent, midpriced receiver, like an Emerson, Soundesign, Sanyo, Panasonic- made for JC Penney.
To be quite honest, there's nothing spectacular about a Panasonic or Sanyo, IMHO. Technics was a high end Panasonic, I have a vintage 1986 Technics 110 WPC rack system, bought it new- don't use it anymore. I use the speakers from it. I also have an old Soundesign receiver that would knock your socks off with fidelity, even though it's only about 10 WPC- paid $100 for it back in 1978 at Kmart, can't bring myself to sell it. It's a silver faced unit with really good transistors in it, and excellent tuner.
At one time, the front panels said "Techics by Panasonic" right on them. I had a quad 8-track recorder with that on it- it was a clunker. Looked impressive, but nothing like an Akai, Roberts, Telex. Heck, not even as good as a Sony or Pioneer.
To be honest, if I had to sell one, I'd sell the Technics. It has an IC amp in it, that burned out and had to be replaced, twice ! The vintage Technics from the 1970's are pretty nice, but being related to Panasonic, actually hurts their reputation. Panasonic never came across as high quality to me, something in that name just sounds cheap.
