Jolida JD100. How good is it?

Gee, this is an old thread. I had to read what I had told you first. I still have mine. I've never used The RCA 5751 triple mica. My favorite is the Sylvania, but they are becoming near impossible to find, and are pushing $100. I think I know where you can get some, but you will have to contact me privately.

I recently bought some much cheaper Electro Harmonix 12AX7 tubes to try on some one's recommendation. the mids were great, but it didn't have the extension of the 5751. There was hardly any difference in perceived loudness between the two.

What kind of 5751 did you use? You were pretty convinced in these old posts that it was the solution! This is my first post by the way!

Rkt008, I have used the RCA 5751 black plates, I like 'em. I just did another tube shootout this past weekend. The RCA 5751s sound great, just a smidge more highs than the EH12ax7s. Depending on your system and room they may be just what the doctor ordered. As far as the reduced gain, you can hardly tell.

My system and room tend to emphasize the highs(metal tweets, Bryston amp, Hardwood floors, silver hybrid cables, no drapes, etc.).

Muralman and I posted back and forth on tube selections. I agree with him completely that the EHs are just a bit laid back. Mural's system surely has quite a bit more resolutiuon than mine and I suspect he can hear differnces I cannot. However, for my system, I prefer the EHs, with the RCAs a very close second. I am seriously looking for the Sylvania 5751s but they are darned hard to find. Eventually I will find some. It may very well be, that I like them better.

Distortion, I was talking about you behind your back. Shame on me.

You bring up an important point. Tube rolling will be important with the Jolida. I can see how Distortion's system benefits from the EH tubes.

RKT008, the Jolida is a marvelout 1k player. Your amp is good. I don't know about the pre, haven't heard it. I do like line stages on most. Speakers?

Break in the RCA/Jolida for an extended time, before making a decision.

For non offending resolving systems the Sylvania 5751 triple mica black plate is the best of the best. Your system might be better suited to some other tubes. This is another great thing about the Jolida, you can taylor it's sound to suit.

I have a virtually new pair of 4004 Mullards I can sell. There are those that think the Mullard is the best. My ultra sensitive speakers picked up too much microphonics on what would have been nice tubes.
