Sksfreund,
Sorry to keep you waiting but I haven't been back to A'gon since a couple days after I last wrote you - I caught that flu that's been going around. Now to try and answer your questions...
So, (deep breath) how do I know that the surface the Maverick was sitting on was "vibrating in time with the midbass exciting a resonance in the player's shell, which in turn constantly engaged the uber-sensitive skip protection circuit - causing the player to consistently sound cheap & BAD"? Simple, all I needed was a little background info. about how cd players function, my system, a cd, some deductive reasoning and my hands. Cd players have a process of correcting data errors by use of a fast-acting error correction circuit called a "CIRC." This is an acronym for Cross Interleaved Reed (Solomon) Code which is essentially a code that instructs a calculator circuit that turns on and "figures out" or "approximates" what the missing or misread data should (or might) be, combines it with the data-stream and sends this slightly incorrect and more mediocre signal on to the dac. This CAN be difficult to distinguish from a cheap dac (with poor quality parts), data mis-clocking artifacts (jitter) or a mechanically poor transport. It's always best (in high-fi anyway) to avoid a problem rather than try and correct it. I admit that it's difficult to discern, by ear, what the problem is but there are lots of things you can try to figure it out. To check whether I'm right you'll simply need to try the NORDOST Pulsar Points isolators (in particular because I can vouch for them and not neccessarily for others)...they aren't just "audio jewelry" -they really do work! You should hear an immediate increase in clarity and subtle detail simultaneously with decreased -if not completely eliminated- vibration. You can easily feel this vibration with your hands by placing them (your hands, not the isolators) on top of your player and your equipment rack.
You'll (assuming the "quick-fix" isolators don't actually "quick-fix" the problem) then want to go through your ENTIRE SYSTEM, i.e. the source cable, preamp, interconnect, amp. and so on, swapping out components listening for the phenomena to track down the culprit. After all, there's just no way that two players -especially as different as those two are from each other- should sound as similar as you're describing they do. Also, don't forget to pay close attention to the power (line conditioning, power cables, all electrical contacts even the wall socket) as your amplifier could be under strain (not getting enough juice as there may be a faulty, corroded or loose connection somewhere down the line.) Any of these "less than optimal" circumstances could be responsible for your system not having the resolving ability to discern these subtle differences. I can give you loads of useful info. on how to go about this and it's all cheaper than 1 set of isolators - but a LOT MORE work.
Secondly, A-B comparisons are not neccessarily always definitive, among other reasons, because the two cdp's don't actually share the same circuit (although I suspect that the problem would still exist if you swapped inputs on the two players) and because the problem is likely elsewhere in the system. Maybe the particular overall sound that the Cambridge has is similar to the MF but not as detailed. Maybe you are simply hearing bad sound that wasn't present in your MF dealer's listening room - like your particular room's acoustics. A-B comparisons aren't my style, but it would be a simple matter to check this theory of yours out by doing some legwork (since I believe that you don't already have another preamp that you could use to test with.) Just find a hi-fi retailer that wouldn't be opposed to letting you bring your 2 cd players in for a listening session/comparo with their high end cd players and amps. A good retailer wouldn't have a problem with that - as it sounds like you might be really serious about upgrading - a little devious & sneaky, but FREE :). If you have deeper pockets, you could just buy another preamp and bring it home, hook it up test it out and bring it back and get your money back. My retailer has no compunctions about doing that for me. Great hi-fi shops are few and far between however. How serious are you about getting the best out of your stereo? I hope that helped give you some options - short of actually returning the cdp and trying another one. I'm always eager & happy (at least to try) to assist a fellow music/stereo enthusiast...let me know. You don't happen to live in Arizona do you - a second pair of ears might help?
-Best of Regards, Bruce
Ps. If you can, try pulling out your speakers further from the front wall as that will allow you to more easily discover totally hidden or subtle staging nuances like whether a vocalist is standing 6 or 12 feet in front of the percussionist. These subtle details/differences can be the difference between the music sounding real or fake - in the room with you or you in theirs.
