CDP-Tube Suggestions

Its tube time again. I would like to try out a different tube in my Jolida JD-100 tube output CD player. It uses a pair of 12ax7s but 5751s will work as well.

I am looking to try a "warm" sounding tube this time around. I am currently using the stock tubes, which BTW, I dont really know what they are. Warm and full vocals with a little taming of the highs is what i am after.

I have tried EH 12ax7s, NOS RCA 5751 blackplates, EI 12ax7s, GE JAN 5751s and found none of them to be all that "warm" in my system. Not that they arent good, I just want something different on the plate so to speak.

The stock Jolida tubes are definately more rolled back in the upper octaves but still sound a little dry, or not robust, in the mids. Especially vocals.

I am thinking NOS Mullards, but I thought I would run this one buy you guys and see what you all thought. Thanks in advance.

When you say you leave the unit powered on 24/7, is the on-off button blue or red in color? You can keep the unit in a semi-on condition (red color), which won't provide tube current, but keeps the unit in a standby mode. I think you can only go to standby mode with the remote, but I could be wrong (too lazy to check the manual!).

Anyway, I bring this up in that it may be a reasonable alternative to "Full-on" mode (blue light). The manual may have more information.

I recommend going for the Sylvania Gold label triple mica blackplates. I cannot beat this tube, and still have a pair of GE triple mica blackplates as my back-up tubes. The Sylvanias are pricey, hard to find, and even harder to beat. My JD-100 came w/Sovteks, and I used them for only about 5 hours. Good luck on your tube rolling.

Also, I recommend upgrading the PC to a Chris VenHaus cryoed Flavor 1 PC. I feel you cannot touch it for the price. It made a huge difference overall, and esp. in the bottom end.

Happy listening.

Russtom, I tried the two GE types and don't care for either. That may not be the answer you are looking for, but that is my opinion, w/ my gear.
