Thanks Bill, Yea I have heard that 37 watts RMS in 1975 is a complete different value today. Never did get a grip on if possible or how to compare the values from different ereas.
I remember when some unsavory marketing was being allowed to boast of ridiculous power ratings at stupidly low prices. Started around the time Pyle was brought to the market.
I can say with confidence that the Sansui sounds as good if not better at 37 watts RMS into 8 Ohms as the so called 145 watts RMS into 6 OHMS (factory rating) of the Sony.
Some day I hope to at least get back to the NAD or Denon level of quality.
