New tubes suggestions?

Hello tube gurus,

I have the Jolida 1000RC which come with Chinese made tubes would like to replace the tubes but since I am no expert in tube rolling I would like some suggestions. Thinking about changing the pre amp tubes and the regular EL 34 with KT77 however I dont know which brand to use that will yield the best performance and musicality. Also, I have the JD 100 Cd player as well. Lastly, any advise on cryo tubes?

Any suggestions will be greatly appreciated, thanks in advance!

I just changed EL34 in my LAmayro int tube amp ( a swedish design) from JJ to winged C and the difference was stunning. The "c":s was so much better.

Yes, winged c's. As for the jolida 100a, my NOS favorites in order are:

Sylvania 5751 gold brand, gold pin: fantastic mids, balanced highs and lows.

GE triple mica black plates 5751.

Mullard cv4004.

But a great tube at a very reasonable price is the new
EI Elite Gold 12ax7. Excellent. As you know, tubes are system dependent. For a good run-down on 12ax7/5751s, google Joe's Tube Lore.

Good luck.
