CD Transports

+1 @curiousjim.

@instlouis, in addition to the excellent SQ produced using I2S, the PSA memory transport reads the disc, then uses a buffer (FPGA) to clock and error correct  the data before outputting the signal. The result is very low jitter and noise being transferred to the DAC.

My portable CD player, a Walkman, employs a buffer. But buffering, it can be demonstrated, doesn’t neutralize the deleterious effects of stray laser light getting into the photodetector. You won’t know it’s a problem until it’s no longer there. Perfect Sound Forever. Yeah, right.

So if I'm remembering correctly, the NuPrime CDT 9 is very jittery for a modern transport.  Is that right?

@instlouis,
So I was just on PS Audio.com, looking for anything about the I’s-1 or I’s-2 connection and found nothing, not even the cable under Products/cables. I haven’t had a chance to call, do you know?

Just curious.

I spent quite some time trying to find a Proof for some of these notions. the most fun part of my activities was posted here.
These last few weeks I found another "proof" that not all spinners are born the same: when setting dBpoweramp CD Ripper onto Secure (recover errors) mode, my Lenovo's internal CD/DVD drive would take HOURS to rip one CD. For practically every track of every CD being ripped, it would try to "recover errors". Before you ask: since I fix Discmans for fun, lens and mechanism were clean. Once I bought this external LG DVD/CD drive, bit-perfect rips are done in minutes.
