Jolida JD100. How good is it?


Have been using my dvd for stereo and would like to improve. The sound is good but not great. Seems shallow. Dymanics are there but blurred together. Looking for a warmer sound and seperation of instruments. Have read reviews on the jolida but would appreciate input and any other suggested players. Price range around 500 and used will be fine unless there are reasons not to go used on a cd player. Listen to all types of music with exception of rap, hip hop, and head slammer.
Current system:
Denon avr 2800 (will go seperates soon), Onkyo integra dvd, Polk audio speakers, Bryston 3b(front two), Velodyne hgs10.

If you find a substitute let us know. I am trying to track down another pair for backup.
Bill Baker of Response Audio likes the RCA 12AU7 clear top - would be worth a try.

Hey lurkers, let us know your favorites.
Where can one obtain the Sylvania 5751 triples or, is availability of these kind of a hit and miss affair? What about the RCA 12AU7s, are they readily available?
The RCA 12AU7 clear tops are readily available from numerous sources. The Sylvania, as plentiful as Sovteks five years ago, are nearly vanished, the demand is so high. The source I have used has only a few left, and, heartless as it may seem, I have a friend (Susan above) that I am holding my tongue for.

I have one spare pair. Both Rt008 and I are looking for a tube that will prove to be a close second. He still likes the Chinese tubes that came with the Jolida. I wonder if I can find mine?
The trouble with recommendations is that one should hear the Sylvania Blackplates first to familarize yourself with its "sound" and qualities before offering up its replacement. I bought my Jolida form Bill Baker but I dont know if he has heard the Joilda with the Sylvania's. Actually all these tubes have some good qualities and Im sure to some they sound fairly mellow and appealing. The Sylvania 5751 Blackplates do some things the others to not especially pitching the sound forward. Liquidity is especially important! We all chasing down tubes to get away from that dry,sterile,soul sapping digital sound.
