I've mainly compared Naim, Marantz, Sony and PC DVD/CD readers.
BTW when I rip a CD on a computer they always come off the CD the same. I mean bit perfect. Unless a CD player has severe tracking errors the data from and CD reader will be the same.
Now I know you'll be telling me the data from a £5000 player will be 'better' than from a £15 DVD/CD player will be better, but frankly it won't be, it will be exactly the same. In fact my PC drive can read a CD at 40x speed with no errors - and DVDs, so intrinsically it's a better drive.
So given that the digital data is exactly the same (and it is, according to a long discussion and series of read tests on DIYAudio), why would the transport make any difference? Well - the only other variable is timing, or more specifically, timing jitter. This is why I have a DAC that re-times the incoming data to it's own digital clock, and in fact I can hook up the £115 UltraMatch to a precision Master Clock to make it even better.
So I'm sorry guys, but digital data is data - pure and simple, and unless you care to re-write the laws of physics and principles of mathematics an error free read of a CD will always be the same (although better on a PC because ripping allows the reader to have a number of passes).
TBH the transport and DAC quality are largely irrelevant to todays appalling mastering of the CD.
Hi globs, Very enjoyable and interesting post. Can I pick your brains on the subject of jitter? As you can see from my sig I have a Dacmagic which up samples, I think. I can't ditect any jitter, what would it sound like? sounds great to me. I know I have very good hearing and usually detect anything out of place straight away. Is jitter hyped up to sell more expensive DACs? Cheers The Limey
