Try a vintage receiver like the luxman R117 or R115. If the unit was well taken care of and the electrolytes are OK they will out perform many modern pieces. Vintage amps can always have new capacitors and wiring and some updated and non updated older Threshold units are better than many modern offerings (IMHO).
Can anything beat Vintage Amps for the $$$?
Restored Fisher, Scott, or Eico integrated amps can all be had for under $500. Do you think any new or used, tube or SS integrated amps can compete in this price range? Any opinions?
