Digital can sound great just listen to Yamaha Keyboards where the Piano sounds fat and analogue like, as Yamaha has years of experience working with digital technology. I like Marantz players for their warm and musical sound. Of course the early days of Compact Disc the sound wasn't good, as factors such as op-amps and the lack of attention to jitter.

Hi and sorry for the late reply.
I have noticed that bad digital, differently from bad analog, have some kind of noise mixed with the signal.
In the analog the noise is there but not "embedded" with the music.
I know it is a strange thing.
But with nice digital the sound of instruments pop up from the background noise like with analog.
I really do not know what is the cause.
And also some vintage dacs when fed properly with a good digital signal sound very good indeed, relaxing powerful but keeping a nice detail.
I really do not know how this happens.
But it happens.
Kind regards,

Well, my Revox is from the early days (1987), and it sounds VERY GOOD!
Much better than some more recent (but lower class) players I have owned!

I do understand jitter probably is still very much there compared to a modern player, but I'm not sure I can hear it? Well, I hear it's not "perfect", but wich CD player less than three grands can be considered "perfect" even now? I think digital has adanced, yes, but that doesn't make players that were very good in the eighties, unlistenable now. It's always a matter of taste and compromise.

I suspect some (not all) of those who have listened recently to an old cd players, have done so with an original one, with old caps and all. Then they say "it sounds like crap", but what they hear is old dried up capacitors and opamps that have seen the death of Elvis Presley. Fresh caps are a must, upgraded opamps can do miracles.

I just put some LM4562 in place of the old NE5532. All I added is some 0,1uF MLCC caps between supply pins and ground, as recommanded.

Very happy with the result!

  Here is a site where reviews were made on CDPs not at the time when they were new, but later after many years of use. I recall listening to a number of these players and I don't agree with the reviews. Here are links to the site:

  Not difficult to figure out why- most of the newer players are made in china. IMO, china= junk.
