Emm Lab CDSA-Se vs Resolution Opus 21.

I added the Revelation cable post-mods, it's not a profound change, but a nice lift to body and tonality, YMMV of course. If I had to pay retail for the cable, may out my money elsewhere, but that wasn't the case and I got to audition it as well. If you love your Valhalla, you know Steve at GNSC can bypass the analog volume which allows you to essentially get the benefits of the DIN connection, but use your rca IC's. You might give him a shout and discuss it with him.

Audience sells a cable configured for this....

To a typical amp you cannot run straight from DIN, as stated above. I think you can to the RW's adjustable gain, but I'd check with Vinnie just to be sure...FWIW, I did not think DIN was a significant improvement to the sound of the RA, the GNSC mods is a whole other ballgame with this player though. Takes it up a few notches in almost every way imaginable. A couple things I did find helped as well is the umbilical cable between the units (I use the Revelation Audio) and the PC (I use the DCCA Source) YMMV, but I thought these were both nice improvements, done after I had it modded by GNSC
