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

Transports not important? Well, something has to spin and read the disc, but any good CD player, ie ML39/390S have significant jitter control built into the player just as their 36 to 360S series of DACs does. As of now, I still prefer the flexibility of a transport and DAC system, ie the 360S DAC is totally software up-gradeable in the field. Cheers. Craig
I'd have to disagree from my experience here. I have a DCS Delius. It's sensitive to transports. Even differnt DVD transports. From the DVD side, I've used a Muse 9 and a Marantz DV-7000. The Muse is much more smooth, the Marantz sharper, more forward, and maybe a touch more detail. The Muse has a BNC out, the Maratz, el cheapo RCA. I've heard the DCS Verdi Transport, and it absolutely smokes the others. It's CD based...
