To tone control or not to tone control


I recently stepped up to a Conrad Johnson PFR preamp to mate with my CJ MF-2200 amp (200 wpc). Was previously running an Adcom GTP-450 pre/tuner which had bass/treble controls which help to compensate for those recordings which are recorded poorly. Though the CJ PFR sounds really good on most of my cd's there are some of my favorite artists whose recordings are really pitiful. Is there a good tone control which I can use on the PFR to use for these poor recordings? Is there a way to connect both preamps to one system. I do have an older cdp that I could connect to the Adcom preamp for the poor cd's and use the main system for the good stuff. I have also thought of trying a subwoofer to help with filling in the bottom end since most of the poor recordings are R&B and Rock N'Roll and that is where they seem to be lacking the most. The rest of my system consists of a Sherwood Newcastle 980 cdp and Infinity RS 5000 speakers (12 yrs old) and next to be replaced. As always your help is appreciated

Guys (gals), don't know if I offended someone(s), I have got -2-2 on all my posts on this thread. Whoever it is, help me do better rather than expect me to understand what i obviously do not. We're here to exchange info, experience around music and its reproduction -- or am I wrong?
Bruce & Greg, I too have received -2 -2 on 5 of my posts on this thread. Even the opening question received neg points. I too would like to know why? I guess I should not have asked such a rediculous question. It seems as if someone doesn't like the topic. Maybe they don't like the TONE of the discussion

Greg, I did try the Adcom in the processor loop as Bruce described. It sounded quite terrible. Had a lot of distortion but it was worth a try. I may try the X-Tune as has been previously suggested (if I can find one) or possibly a subwoofer

Bruce, Thanks for the suggestion. Even though it didn't work
would be no reason for me to leave neg points.
I'm suprised it was distorted. Oh well, experimenting is half the fun. Did you make sure to turn the volume on the adcom down so it didn't overload the CJ?
Bruce, Yes I had the Adcom's volume matching that of the CJ. However maybe it was overloading the CJ since I had to turn it up to nearly half volume to match the CJ. Maybe turning the volume down on the Adcom would help. Didn't think about that till just now. I just tried it Sunday night and didn't play with it very much. I'll try that and see what happens and let you know the outcome. Thanks again
I am sick of all this rating crap. What say we all just don't look at ratings. We could take the quantum approach and say that unless something is observed it does not exist.
