Depending on the jitter reduction circuitry in the DAC, the differences from one tramsport to another may be quite marginal, but noticeable.
Reducing or eliminating jitter is key to attaining great digital audio or video reproduction, both transport and DAC play roles in this action.
The Big Sony SCD 777s were made like tanks and provided solid transport sources as they were very well damped and designed. They are also quite mature now. I tried out two DACs who reportedly are great at jitter reduction, a Lavry DA 10, and BC DAC3.
In both cases the sound improved regardless which DAC was being used. I also had a new Oppo 980 player and attached it to each one in turn thereafter, so as to see for myself a little bit about this topic.
Yes again... the sound was improved upon regardless the one box CD player in use as transport.
BUT... the SCD xa777 used as transport only, was the better and more accurate sounding device of the two drive units being assessed.
How much better? Noticeably, but not by a lot. I've trouble with quantifying that difference numerically. Maybe 20%, perhaps less. Probably less. 15% seems to fit. it took being familiar with both units and with both DACs over a little bit of time for me to distinguish the diffs.
The Sony SCD xa777 cost me $1100 used. The Oppo 980 ran me $175 new... effectively a diff of $2800 or so using MSRP as new pricing for each CDP. Or about a grand going with preowned pricing. A grand for 15% may appeal to some and be within their designs for acquiring
but for myself it usually is not an investment id make readily.
Without such a first hand comparison either unit as transport would surely suffice.
you'll have to decide where best to drop the budget... DAC or Trans. My money is on the DAC in that race. however I've proven if only to myself, a better transport (if a two box solution is desired) will be beneficial. Albeit the benefit becomes that of marginal to modest to, ??? as the transport/DAC combo performance and expenditures increase.
Whatever the case though, unless some major bucks are invested and some extensive comparisons are made, I'd not be expecting any of those night & day astonishing diffs from one trans to another. Noticeable though? yeah. Noticeable gains should be easy enough a task to acquire.
that one point alone is likely contributing to so many people exchanging two box solutions for Hard Drive based sources instead of single disc players.
It always is the same thing
how much money and time are you willing to waste well in ascertaining and implementing a thing into ones rig?
Arguably of course, but quite often, in high end audio, Ive found ignorance is bliss
. and a lot cheaper too.
Good luck
