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.

Interesting thread. I think the Sovtek 12AX7WA exhibits a slightly warmer and more robust sound than the stock, EH and Telso JJ tubes in the JD-100. At the same time it tames the highs well without sounding appreciably more rolled off than any of the others. Drawbacks? Well, I think it just lacks a touch of clarity compared to the EH and the stock tubes. But, this is a close call.

In any event, at less than $10 for a pair it is a no brainer to add them to your inventory.

In the meantime, I off looking for some alternates as suggested in this thread.
