My favorites are Technics,...
of which I have many. You could say Technics "RS", but that's a family of about a hundred drives, from low end to high end. The really nice ones are at least
RS-B48, RS-B50, RS-B78R, and my favorite of all time is the high end and hard to find
RS-955!!! Some older ones would be RS-M234, RS-
M240, RS-M270, etc. All these Technics "RS" cassette decks I've mentioned are relatively high end, with Dolby and dbx NR. I'm partial to dbx. Forget the rest, (like RS-B11, RS-B17, etc.,... are junk!) Need I say more?
Oh, yeah! Some newer Technics that I'll recommend are RS-B465 and RS-B555, both with Dolby B/C and HX-Pro. They're pretty decent drives.
Sure, I have some Sonys (TCE-W375) and TEACs, too, which are decent enough to mention. Can't remember all the model numbers, though.
Aw heck! Get 'em all!.....
