Jolida JD100. How good is it?

Hi Distortion,

After following all your posts, I bought Modified JD-100 from Underwoodwally, it came with svets, as per your obervations I ordered EH12ax7 and I am really happy, this tube is better than Svets's, recently I found that now Underwoodwally is offering level 2 mods on this CD-P, and the tubes he is offering with it are NOS GE-5751 (Not sure whether those are triple mica), So now I am also looking for Good 5751's, I already have new GE 5751 with green lettering, but I never liked thise with Jolida Amp, hopefully will try that one some time, Another variant I tried in Jolida Amp was RCA 7025 (I will post the exact number afterwards), which was better than all 12AX7 I had at that time, but as Walter wasn't keen on substituting those for 12AX7, I haven't tried those.

Thanks a lot for posting all your finding about the tubes, that's the reason I skipped everything and went to EH12AX7.

Thanks,

The GE grey plate is reportedly the least of the 5751 tubes. It can be brash, and a bit less liquid. Still, not a bad tube. The Svetlanas are decent tubes, but we have been talking about far better. I'm curious about the Sovtek 5751. I have never heard a report on them.

Playing my new JD-100 with the stock chinese tubes I am amazed at how good the sound is on certain recordings. A CD of the Barber Violin concerto is all one could ask for. Seductively lush and warm yet it doesnt hang back in the soundstage. It is detailed and dynamic and yet retains the warmth and liquidity that is so appealing to me.The problem I have with my system is just a little too much edge with loud passages on certain recordings.This may correct itself with a sustained breaking in of the player though. I am wondering for those of you who have found the "perfect tube" are there still recordings that sound harsh or edgy? Or does tube Heaven cure a multitude of sins?

Given you cdp is healthy, it would have to be the tubes, or downstream components that are straining.

The words, harsh, edgy, just aren't in the Joida's vocabulary. It may be the tubes; I can't remember. There are always those pesky downstream components. Any of them may be spoiling the pot.

Muralman, I dont blame the Jolida by any means.The Musical Fidelity amp and the Jolida as well as the Harmonic Technlogy Interconnects have pushed my system to a level where I am very close to what I consider perfection. There may be no such as perfection given the variable nature of recordings however. No matter how good a system is I bet I can find a recording to make it sound bad! I guess my question is (with my inexperience in tube rolling) how great a difference is there with a selected reference recordings in the tubes you have tried? Do different tubes improve the sound in subtle different ways or is the difference profound and dramatic?
