problems with 24 bit cd players


i am searching for a cd player--preferably one with tubes.

i have auditioned a number of them and something is wrong. i perceive a dip in the 100 to 200hz region and a slight peak in the upper mids/lower treble region.

is it possible that one can buy a current production player which is 20 bit and no up sampling ?

i haven't found any, nor am i looking for a dac, although i am aware that there exists non-upsampling dacs.

The digital to analog portion has to be solid state
Why? Partly, for sure, but why all the way? I wouldn't personally see any reason to insert tubes in there -- but couldn't you construct a tube thingy if it tickled your fancy?
my reference cd player is the audionote cd 2 from 1994. it takes a 12 volt tube. i am using a ge 5751 blackplate. i have compared many cd players and none comes close.

yes, some would consider the audionote overly subtractively colored, but whatever deficiencies the magnepan has, the problems which i usually identify--brightness and a lack of warmth are not an issue when the audionote is in my system. i am looking for a cd player which sounds as close as possible to the audionote.

with respect to the paradisea dac, will an oppo cd player as transport suffice to produce the euphonic presentation that supposedly is its character ?

Greg, the digital to analog conversion is done with an intergrated circuit. Digital goes into the chip and an analog signal comes out. It is all done inside the chip.

digital signal in ------ chip -------- analog output

You can add tubes at that point but the conversion is done.

Mr. Tennis, why are you looking for a player that is as close as posssible to the Audio Note? If you revere this player and need another one just buy another Audio Note. If you are as thrilled as you seem to be and only hope to come close to it's performance why would you want to replace it? This looks like yet another Mr. Tennis troll.
