A BX-125 became my 2nd cassette deck, after my fine Harmon-Kardon HK2000. I'm a happy fan. These sound great: you feel you're hearing the most out of any cassette recording. My audio system has improved greatly over the years, but the Nak has kept up.

I have had this deck forever now, it has never had a problem until recently. I can't be positive enough on how this deck has sounded and played now for the past 20 years. I have done countless a/b testing and it always seams flawless.
I use maxell xl2s



re: BX-125

I got one for $5 at a St Vincent DePaul. A tape was stuck in it and it was locked in Pause. The camshaft was jammed. I had to open the bottom and turn the worm gear with my finger. It seems like a nice deck. I think I'll have to adjust the tape head.
