I bought a Nakamichi receiver back in 1988, the SR-2a which finally died on me back in 2009 after I moved to a new condo. I heard it was hard to find parts so I ended up dumping it. I ended up getting a Sony AV receiver to replace it. Found an STR-DE835 which was likely originally bought in 1999 but was clean so I paid $120 for it on Craigslist. Its a great receiver for my home theater but I've been exploring 2-channel options and saw a Nakamichi TA-1a on Craigslist and got it for $35. I realized it was not a Stasis receiver like my old SR-2a was. It sounds good but was wondering if there is significant differences. I guess the SR line of receivers all had the Stasis amp technology but Nakamichi only put the Stasis amp in their TA-2a models and above. I don't have any manuals or brochures from the TA-1a or the TA-2a so wanted to know if the technology is drastically different and how that may affect the sound. Thanks for any insight.
