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.

I would agree with "hyper detailed" and if that is not to your liking I suggest a non over sampled player is your best bet. I'm not sure about one box players but why not a DAC? I'm not as familiar with the players but there are quite a few DACs. Check my system for one approach.

hi tvad:

i prefer not to purchase a separate dac and transport.

are the non over sampling dacs tube based and 20 bit ? i already listened to an ack! dac and scott nixon tube dac. i was not impressed with either.

i suppose if i heard a dac/transport combination that was sufficiently pleasantly euphonic i might reconsider my aversion to a dac.
YBA claimed for a long time that 24-bit was detrimental to musicality and their CDP were dual 18-bit only, against the marketing hype. They moved to 24-bit now but if you hear dips and what to move away from 24-bits, get a used YBA CD1 or 2 or 3 Alpha and enjoy the bitless effort!
