As has been pointed out before, Theta, the originators of separate transports/DAC's for CD, no longer manufacture a CD-based transport - their current models all utilize DVD-based mechanisms, and they feel that these are better even for Redbook CD playback. I don't know if I would go so far as to say that transports aren't important any longer, though. I don't have a high bit-rate, upsampling, or DVD transport-based digital playback system, but I have heard too many differences among transports, even with a reclocking jitter-reduction device in the chain, to believe that the issue has become irrelevent without some sort of comparative proof.
Transports not important any longer?
Hello all,
As serious readers of the forum may remember, I just purchased an SFD-MKIII and DSD upsampler. I'm already finding the music to be a major improvement over my old Arcam FMJ. Another league to be honest.
Anyway, I spoke with Chris - the original founder of Sonic Frontiers (now at www.partsconnexion.com) and he said that my DVP-9000ES DVD/SACD should be a perfectly fine transport, and that though AES/EBU would be nice, it really is no longer necessary.
His reasonsing is that the SP/DIF stream is reclocked when it is upsampled in the D2D and then passed on to the DAC via the I2SE cable - and jitter drops to an astoundingly low .4ps. And jitter is not reintroduced from the upsampler to the DAC because of the clock comes to the via the I2SE.
I found this discussion quite interesting, but would love to hear other comments. To be quite honest, the sound coming out of my 9000ES->DSD->SF SFD-MKIII is astounding.
Nonetheless, like all audio-obsessed types, I wonder..
I assume this applies to the Perpetual Technologies DACs, etc.. anything which connects the upsampler to the DAC with a jitter-free connection (firewire, I2SE, and I assume I2S).
Just curious,
Adam
