Are all red book cd transports created equal?


Quite simply the transport on my rega Jupiter is failing and I have an old pdr-19rw pioneer elite that has the same digital output. In theory bits are bits right? Should I swap them out or will the old unit sound as inferior as all those original cd’s did?

There are no bits on a CD. What you think are bits are really pits and land ... Since the length of the pit or land is what determines the string then timing matters which means when you really get right down to it its analog not digital.
This is especially convoluted pretzel logic. A CD is not analog. It contains a non-continuous, discrete string of data that is not an "analog" of any signal, but a mathematical representation of a signal. That’s what digital is. The timing issue - for the purpose of resolving data - is functionally perfect. Timing data is included in the data string and any error is trivial compared to even the best analog. That’s why you can install even a complex computer OS from a digital disc without issue. The data is absolutely the same every time.

I’m not saying digital is perfect, by the way, and getting digital data from disc to DAC and out to analog is not a trivial task when fidelity is the goal. But CD is not analog. Not even close.
The only way to know is try and hear for yourself.
I agree there. That is always, always, always the case.
