I agree with Whatjd's comments above. I know my Vitus SCD-025MkII cdp uses discrete analogue stages derived from the SL-102 preamp. I've also replaced stock 4 x OPA627AP ic op amps in my previous Ayon CD-5s with Burson Single HD discrete op amps and have heard the improvement with my own ears. Basically music sounded less digital (more analogue), music came from a blacker background, bass improved & soundstage width doubled. The difference to my ears was clear.
