that one is known to be not exactly dead neutral in sound, but it clears up with an external DAC, so possibly something getting into the DAC Vref? (This has caused issues with different sound on bit-identical CDs in the past - DAC Vref was being influenced by the servo circuitry.) One of these days I'll have to get some CD-Rs (I don't think I even have any anymore) and burn RMAA test tracks onto one to test my trusty Onkyo DX-6920. If both tracks are sample-aligned and you invert one, the difference should be a solid digital zero. What I would suggest doing is trying to capture the SPDIF data stream via a soundcard with optical in (OK - possibly easier said than done), perhaps on a disc that's not easy to read, and comparing the recording with the same track conventionally ripped and verified. If the optics are dirty, adjustments are out or the odd electrolytic capacitor has seen better days (the KSS-240A in this unit is quite notorious for a little SMD electrolytic going bad, as they almost universally do in this time frame), the player may be making copious use of interpolation without it being too obvious (as that's what interpolation was designed to do). Note that a nigh 30-year-old CD player may no longer work as new. Just want to know if there would be a significant improvement going for a brand new modern CD player (entry level). I don't know what I got but it sounds very, very good. Well, if someone can comment on the specifications shown on the above link I would appreciate. What is "PULSE DAC"? Is it a good thing to have a PULSE dac (whatever that means)?Īlso, in the link above specifications say: "Digital converter: CXD2561M " What is that? Good? Bad? Would I get a much better DAC if I buy an entry level modern (2020) CD Player? What does that mean? Is it a good DAC inside? Or is it a piece of junk of old crap DAC? This Sony CD player has a front label that says "PULSE D/A CONVERTER" Now I have read that modern DACs in CD players are superior than older ones, even in entry level cheap players. Besides, it plays perfectly any CD, new ones, old ones, scratched ones, home made ones (CD-R, etc), anything it plays without effort. It sounds very good to my ears, very clear, very neat, crystal clear sound. I got a Sony CD player from 1992, it is the CDP-C715: Here I refer to entry level (cheap/inexpensive) CD players only. Particularly, I would like to know about how much better is a current DAC vs an old one. Im curious as to know how much of a difference is there in entry level CD players from the 90s as compared to current ones.
