Does the Transport make a significant difference?


Had been running a squeezebox with my Audio Note 2.1 Dac. Tried my basic Oppo dvd player as a transport and yikes what an improvement - even over my $3,000 invested Modwright Sony player (a little rough round the edges but dynamic and live-ly sounding). So wondering if the mantra of having a great source is the best place to start ... ie matching the Dac to a quality transport say CEC TL 51 or open the vaults and spring for a quality Audio Note, Esoteric, or even dcs transport will be worth the investment. How does this compare with say upgrading your amp or speakers or even cables? I know I should listen for myself but any good experience out there to draw on before I start getting crazy about checking out the used adverts?

Shadorne - I was under impression that we discuss sonic differences of different transports with the same DAC and not comparing DAC with stand alone CDP. At least that was the purpose of the thread and my reply to Douglas statement below:

"In my article I point out that a jitter eliminating DAC (the Benchmark) can help raise the performance of the poor transport, but it will not make it the sonic equivalent of the finer transport. There are still fundamental sonic differences. The distinction between them becomes even more profound in higher end rigs, even if the same jitter nullifying DAC is used. "
My bad doug you review for dagogo. I get you to mixed up and yes i do enjoy your review also.

That was the way I understood it too. It doesn't matter anyway as I am quite happy if we all understand each other in the end - and I think ultimately we do. My english/spelling is not great and I rarely double check my quickly written posts. I think in equations/math more easily which is why I am quite comfortable with listening to digital and more interested in the technical rather than aesthetic side of this hobby ;-)
