One of these is a 2000 Single bit CD player, the other is a modern 16 bit  player both from the same manufacturer

And I would take whatever comes from this website with a grain of salt:

This is a simple realization, but you can explain a whole musical world with it. The characteristic construction and material of your ear is the yardstick, and the more a sound comes close to that characteristic, the better you feel and the more you are attracted to that sound.

i've had a rega cd player that came with 1-bit dacs, one on each channel. The sound of this player was very "analogue" and quite dark sounding... very much the headphone equivalent of the Senn HD650 or LCD-2. not sure about hearing noise-to-signal ratio, the music from this player was very enjoyable. of course there are other components along the chain, but I'm quite sure the 1-bit dacs had a lot to do with the sound.

I'm acuallty trying to choose between cd players, http://www.teac.co.uk/products/separates-PD-D2620.php has the 1bit dual dac, claims signal to noise of over 100db, but is 20hz-20khz -+2 which is more frequency roll off than my speaker amp, my speaker amp is 20hz-20khz -+0.5 and it has a much harder job, the other is a http://www.us.onkyo.com/model.cfm?m=DX-C390&class=Compact Disc&p=s , it has a 24bit dac, claims 5 Hz-20 kHz which I would guess is -/+3db, signal to noise is 96db. I currently have a phillips cd630 which has 2x 16bit chips and claims 2hz-20khz which i would guess is -/+3db, and claims 110db signal to noise. I'm replacing the phillips because it's digital out doesn't work with my emu-404 and it only holds 1 cd but I don't want to replace it with something that is worse.

But is it "true" 24-bit, or a 1-bit DAC that claims to achieve the resolution of 24-bit?
