Jolida JD100. How good is it?

My Sylvania 5751 Triple mica blackplates have finally arrived and have been cooking in my system for about 8 hours.Now this is more like it! Much better than the Sylvania grey plates or the RCA. I am wondering if the grey plates and the RCA were weeded out tubes from a larger batch. There are variables within the same make. I have read that out of every ten made usually only 4 are up to the standards needed for high quality audio. The Sylvania blackplates are the tube to get. The stock chinese tubes are my second choice. If you can find an RCA its worth a listen.....

Rkt008, end their suffering, and tell them you are just joking ;-)

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.
