modified jolida 100, mh cd-25, or audio aero prima

I am in the process of researching a new cd player for my system and see to many choices. My system consists of marantx sr8000 as a pre, mca 50 amp, paradigm 80's front, 40's rear, and cc. I listen to music/Ht 50/50. I would like a good red book cd player for my system. I see some very good reviews for both the modified Jolida and MH. I am also interested in the audio aero prima. My budget is in the 1k to 2K range. The modified players seem very reasonable. My location does not permit me to audition these players. Your experience and expertise would be appreciated.

Thats good info Crgolfer, I havent used Sylvania tubes yet, but I have read that many folks like them. Are the Sylvanias 5751s or 12ax7s?

I have been using Vibrapods for isolation and a MIT Zcord power cable. I am thinking of upgrading the PC. Any recommendations?

I have had a pair of EI 12ax7ln's tubes in for a week or so. I really like these tubes.

Muralman, have your EH tubes arrived yet. I am interested in your opinions on these.

I'm running them now, for the first time, Distortion. I don't hear the microphonics that plague nearly all 12AX7 tubes. The mids are very good. There is a trade off between the EH tubes and the Sylvania 5751 black plates (my personal favorite). The EH tubes are gently rolled off. This gives a softer, not unpleasant female voice. The bass is more soft, but forgiveable. Because of the roll off, the EH tube is not as concise or detailed as the Sylvania.

I will give the EH tube high marks, though, because compared to all 12AX7 tubes I have tried (Mullard, Telefunken, Phillips, etc.) the EH is the most enjoyable, and they don't call attention to themselves, their faults being relatively minor.

Now I have switched back to the Sylvanias. The roll off is gone, and the leading edge, so important for transparency, is fully restored. The bass has tightened, as I knew it would.

I am surprised that the 25% less gain of the 5751 isn't pronounced. That might be because of the higher treble energy.

For casual listening, I will keep the Electro Harmonix in the stable. Thanks for the tip, Distortion.

Muralman, its been a pleasure discussing tubes with you and the others in this thread. Thank you, for all the input. I think you hit the nail on the head with the description of the EH tubes. Did you notice any change in imaging or depth with the EHs?

I agree about the gain, the difference is hardly detectable.

I am gonna try out those Sylvania's if I can find some, I will revisit this thread when/if I do. I think Upscaleaudio.com has some.

Thanks again all, and enjoy.
