Rives PARC parametric equalizer

Thanks to Shadorne and Rives the inventor of the PRAC for your insights. As i stated i like to hear from folks who have used the device. If you are not one of them, please don't bother. I am a PARC user. In my system, i love what it does to attenuate the bass boom from the standing waves in the 35-45 hz range. However, I can subjectively hear that it subtlely curtails the dynamic contrasts and sucks some life out of the overall sound of my LPs. I only attentuate at 40hz. Further up I don't have problematic peaks. instead i have some suck outs in the 100 to 200 hz range.
I am using a power cord and ICs costing the same as the PARC to feed the PARC. I would like to hear from other PARC users whether they hear anything similar to my experience. And was it bothersome?

Tks Rives and sorry for late reply...been travelling.. I have obviously tried the bypass mode vs taking the PARC entirely out of the chain. in my system and to my ears, the PARC does something to the sound besides attenuating bass booms. E.g.,the usual slight hiss from my tube pre-amp is greatly surppresed with the PARC in the chain, whether bypass mode is on or off. I don't know if the extra ic causes that.
I prefer PARC out of the chain. However, it would make the bass boom unbearing to listening. So it is a compromise.

Shadorne, in my system and to my ears, the PARC is not transparent in the mid and treble as some reputable magazines have claimed. In addition, in my system, it takes some life out of the sound. However, I must hasten to add that using good quality power cord and i.c. to feed the PARC will reduce the gaps to a subtle level. The PC i use on the PARC costs the same as the PARC (isn't it ridiculous?) but it does help to put most of the life back into the sound again. Before that i used a much humbler PC, and the sound was dissaponting.

My PARC is also fed by Exactpower EP 15A. I dont know if it may affect PARC adversely. Anyway in this configuration, and to my ears, attentuation of bass boom not withstanding, the PARC is not transparent compared to if it is out of the chain. A good PC certainly helps to close the gap though.
