A forty + year old amp will soon starting having issues if it doesn't already. The capacitors alone should be replaced immediately.
While I somewhat agree with the above sentiment that SS amplification has already reached sonic nirvana, that kind of misses the point. Sonic excellence has gotten within reach of the lowly budget audiophile. What used to be available only to the well heeled or wealthy for multiple thousands can now be had, for the most part, for pennies on the dollar.
Schiit is one of the price leaders in this regard. No idea whether the Vidar would have synergy with the OP's speakers, but I agree that it should be on anyone's short list. I've got one, and it does sound quite good with 4 different brand speakers that I've currently got.
