That Technics is a fundamentally good deck but I'm told the SQ is ruined by some component choices. Alex Nikitin (ANT Audio) has made a few very straightforward changes to this deck and reportedly acheived stunning results.
In stock form I found the RS-B965 was easily outperformed by the RS-BX808/828 - the latter remains the best of the Technics decks (in stock form) in my opinion. Over the years I have owned or listened to just about all the best of the Technics range.
You guys have got me remembering my first Cassette deck in the early 80s which was a Pioneer CT 506 (as featured in this Youtube video)
- it sure was bang tidy, I think I need to find one on ebay for pure the hell of it
