For many years I had a second hand Sony CDP-710 (with the glorious TDA1541 DAC :-). I loved that. Its sound was so natural, I didn't think about hifi, I just listened to music. I like Sony's features also, that is everything I need for music playing.

Now if you look at the 1kHz FFT at 0dBFS, you'll see that THD was -88dB = 0.00398%; perfect match ;-).<br />Archimagohttps://www.blogger.com/profile/08642574001287787545noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-21295605641908375552022-01-12T20:46:58.499-08:002022-01-12T20:46:58.499-08:00Hey Duck,

I bought it in 1985 (it was a 1984 model) and it was true 16 bits, dual 4x oversampling DAC with analog filters. It sounded better than my Linn LP12 even with those early CDs. The CD player was stolen a few years later and replaced with a Yamaha (1990) and a NAD (2012).
