Marsh P2000T hybrid preamp....Should I modify??


First, I'd like to say how much I've enjoyed reading and learning about high end audio on this site!!

In regards to my question, I am seriously thinking that a modification of the Marsh P2000T is in order. My system consist of a Pioneer Elite PDR-19RW CD player/recorder, Marsh P2000T preamp, Marsh A400s amp, and Magnepan 1.6's.

After reading in this forum about microphonics, I can say that this preamp has a problem in that area. Another issue is that I can only turn the volume control up to about 11:00 or the blue LED on the A400s starts blinking!! It does get relatively loud. I got this preamp as a demo from Audio Advisor for $975, so I could afford a modification. I am thinking that I would send it to Underwood HiFi for the mods. The mod talks about reducing microphonics and lowering the gain from 23dB to 14dB. Those 2 items address problems that I've mentioned earlier.

BTW, I will be replacing the Elite CD player/recorder with a Music Hall CD-25, also modified , either by Underwood or Sound Odyssey. Thanks for your time and thoughts on this matter!!

Well, how does the darned thing sound after the upgrade ? I am installing Gold Point attenuators shortly and plan to add at least some of the commercial mods via homemade tinkering...
It is still breaking in, but I can report very good sound so far. I am also breaking in an Onyx XCD-88 mod unit that I bought from Underwood.

I'll send you a couple pics Dimitry!!
After about 200 hours of burn-in and some new sub cables, everything about the sound of my system is BETTER!! I can now turn to listening to the music instead of the system!!

Here are a few pics if you are interested...
