I had decks from Sony, Akai, JVC. The best machine I used to have was the Akai GXC760D. The GXC760d was the top model of Akai at the time.
I now have the Yamaha KX580 Special Edition.
This deck is particularly good quality. The sound quality is better than the Akai GXC760d.
No noise, low and stable wow & flutter, excellent dynamics.
Pre-recorded music cassettes sound excellent on this deck.
Records perfectly and also sounds great on other decks.

The KX580 Special Edition is an excellent two head machine that sounds like a three head deck and is also very reliable.
The KX580 Special Edition = BabyNak Underdog :D

This is a very capable 2 head cassette deck and has very good sound quality. It has been my number one deck for a few years now and is still on it's original belts which are in good condition. One problem that has reared it's head recently has been a clicking sound that appears to originate from the take up reel mechanism drive gears which is causing a modulation to appear on a continuous tone but is not noticeable on music. There is the choice of manual or auto bias which appears to work well on all tape types and for those worried about hiss Dolby appears in B, C & S forms and HxPro is also standard. Sound quality is pretty good, the differences between the original and the recording to my ears are minimal with half decent tape. Well worth finding a good one if you can.

Yep. Got spot-on with speed pot - though adjusting it feels like stirring jelly. While inside, I glued a pair of leds inside the cassette flap so I can see my old tapes tangling along. Borrowed power from plus minus 7.5 V at rear of board (always on) with 1k in series. There may well be a more convenient (switched) tap-in if you're prepared to explore.
Music really sounds better on-pitch.

re: KX-580

Outstandingly helpful and functional website!!! My KX-580 sat on a shelf too long. Mechanically excellent, and response is so good, it reproduces the 19kHz Zenith pilot tone on tapes made years ago from FM. However, a spectrum on that confirmed the deck to be running slow, one percent, relative to the original Trio/Kenwood recorder. That's just enough to make music sound slightly 'off'. Now with all due care, I'm heading for that secret pot on the back of the motor! Very grateful to the guy who uploaded the pdf.
