Thank you or this indeed. I actually have a sony professional cdp d500 as my main cd player and I love it. In the Sony this is the same chip, pcm 1702, but in dual mono configuration, I couldn’t know If it gives it a benefit to use 2. Probably because it makes it easier to have balance outputs would be the reason for this. Funny thing is, it is, subjectively a great sounding cd player, but obviously only used for 16 bits redbook cds. I had it hooked to a modern dac, but lately for kicks I went back to use the r2r one. there is definitely an audible difference, and knew full well that it’s not as accurate than modern delta sigma dacs, but somehow I like it. I don’t want to get into the reviewer senseless lingo here to describe the sound, but it’s pleasing to me... (being political here... I know what I like about it... ) I know, subjectivity... Way back I worked in radio broadcasting, so I´m very familiar with he sound of em and it might be this familiarity that makes me biased. On another note, it’s not relevent to this review, but it’s sound is not the main reason I like this cdp. It’s such a robust hyper reliable thing, with great tactile feedback, ultra fast loading, and any cuing functions you can think of, and obviously all kind of digital outs, including aes ebu. I wouldn’t want anything else for cd transport at any price. They sometime show up around 200$ in the used market and it’s a great score for anybody that uses cds.
