Yes,
But it is not about specs,that's marketing one up-manship, keep in mind, the main brands made their reputations with receivers, then separates .... Of course old equipment needs to be checked/renewed by a pro, components drift out of original specs ...You still have the split, TUBES or SS. And early Transistors vs later with better transformers ...
I have 2 Fisher 500C Tube Receivers,
One is at VAS getting it’s tuner aligned.
Main one, I loan to friends when their equip is in the shop. Everyone is surprised how good it sounds.
SS: I’ve got a Yamaha CR1040, two sets of speakers, shop and basement system, sounds darn good
Onkyo AVR, Current Sony AVR, they are nothing to sneeze at.
Many times we hear our better equipment thru the better speakers, thus
