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

Dekay & Gregm, I saw a picture of the MF x-tone. From what I could see it looked like a 2 band parametric type EQ. Is this correct and is it your opinion that it would sound better than running the Adcom thru the processor loop as Bruce has suggested?
Artemus: I have never used the unit, but had talked to MegaSam awhile back about one that he was selling. I seem to recall that it had four seperate crossover/turnover points (I may be wrong on this) and that what it did well was to tailor the highs and lows without mucking up the midrange. I have never used any type of inexpensive tone control that did not "damage" the mids with the exception of a Quad of England preamp that had some type of variable adjustment (that I did not quite understand) but that worked very well. If it spares the mids, then I think that it would be worth a try, plus it's small and should be easy to incorporate. In the meantime though I would just play around with the Adcom (which is at hand) and wait to see what else is available. If the Adcom is that unpleasent in the chain then move forward.
Hi Artemus, wish I could help more. As Dekay, I never used this in my system. Sonically, the mid-range darkened only by a tad, the bass was boosted and the highs became more pronounced and a bit harder -- but at least, one got a simulation of highs... I remember (may be wrong on this) the x-tone being connected between source component & line input; this setup may sound better than going thru the tape-loop.
Not much to go on, I'm afraid.
But, do play around with your adcom, as bruce & dekay suggest, it may offer an acceptable solution.
Perhaps I'm a bit daft, but the logic of the prevailing "straight wire with gain ... equalization=distortion" paradigm really mystifies me. The underlying premise that I read in most of the above thread is that EQ violates the purity of the source material.

Throwing caution about being flamed to the wind, may I ask a simple question? What happens in the mixing studio -- if it is a "straight wire with gain" kind of process, then why is it called a MIXING studio? Don't they equalize the bejabbers out of the performance that is being recorded? And if so, does equalization only become pernicious after that point?

To me, this is the logical equivalent of my local municipality refusing to treat the water that they pump from the river because they don't want to adulterate the purity of it. If indeed the water were pure, this would make sense but it doesn't because every upstream municipality dumps their treated sewage water into the river. How does this differ fundamentally from equalizing that which has already been equalized?

Just curious :-)

To me, this is the logical equivalent of my local municipality refusing to treat the water that they pump from the river because they don't want to adulterate the purity of it. If indeed the water were pure, this would make perfect sense but it doesn't because every upstream municipality dumps their treated sewage water into the river.

So ... is there "good" equalization and "bad" equalization? Is it solely dependent on when it is done or who does it? What rules are we going to invent to help us out of this logical predicament?

Just curious :-)
