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.

I wish I was joking. I was perfectly happy with the chinese stock tubes until I heard the Sylvania Blackplates. This tube has it all! Its smooth ,detailed,very liquid,the sounstage is huge! The RCA and the greyplates had some of these qualities but the sound was very dry and that for me is a no-no. It may be that they were cast outs from a bad batch. The Sylvania Blackplates also pitch the sound forward. This puts vocals right in your lap. That may bother some people but I love it! Also there is a nice sense of air and bloom around the instruments. This is the Holy Grail! Sell the kids,auction off the mother-in-law,steal from the collection basket,pay any price but find this tube!
The Sylvania - Exactly like I hear it. I still want to find a cheap gold plate cup substitute for the Holy Grail.
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?
