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?

Interesting how a simple question can lead to controversy!
Look who started it, a fuser 🤷‍♂️
I see no point in engaging folks who speaks from ignorance.
Contradictions/oxymoron , so why engage me, seems you you don’t know which way is up🤦‍♂️

Open your mind my friend and go listen to a decent streaming setup at your friend’s place or a dealer.
Don’t have to, they bring there streaming stuff here and put it in my system, and then are shocked when the same is played on my CD transport. So go peddle yourself🤦‍♂️


I am a fuse adopter with a digital front end. My system has combination of SR Black’s and HiFi Tuning Supreme Au/Ag and Cu Fuses.

And real rich coming from a fuser


I would use Pioneer player in the interim and invest in a high quality streamer with internal hard drive so you can enjoy bit perfect rips of your CD’s.

This will only be close to bit perfect if he uses a good CD transport, other wise there’ll be errors and jitter transferred to the HD.
Then there’s write and read back errors from the HD, probably powered by an smp, so noise to add to that also.
I’ve yet to hear a streamer/hd sound as good as a proper CD transport playing the same CD.

I have the option of burning

Don’t burn, much more errors come with doing this, that why they nearly always sound brighter, and less easy to listen to.

Now you can see why the error increases the pits/lands are deformed.

There are differences, read error correction is not the same and can vary quite considerably between CD transports, and an error is replaced (guessed) by what came before it, a 1 or 0 and it only gets it right 50% of the time.
As well as the amount of jitter out of that spidf output, which I had a jitter counter to read it and they are very different.

Better transports have less read errors, and better jitter on their outputs.
If you want another good cheap CD transport, get a Cambridge Audio CXC very good, not the best, but you have to pay big bucks for those and not that much better.
