Transport - does it matter to the sound at all?


I wanted to start this thread, to gain some insight into peoples experiences on this subject.
My view: From the outset of CD and digital media, we were force fed the view that 'its digital so always sounds the same whatever' ideology. Remember the jam on the cd, and it doesn't skip. Since these naive beginning we quickly found out it did matter, and the quality of components, interconnects (its wire isn't it so doesn't affect the sound?) and design DID affect the sound. So I firmly believe that a transport does affect the signal quality and final sound output in a big way. There are transformers, capacitors, boards, wires, all the components that have such a bearing on quality output on all the other components in a system. And the motor, the bearings, the transport mechanism, jitter correction, noise, damping, vibration from itself and speaker interaction ALL will affect the sound.

My question, what are the views on this balance between cost on a DAC and the transport. Are many of us getting it wrong bolting on Sony DVD players to high quality DACs? And are many of the 'quality transports" out there just re-boxed philips units. It does appear very few manufactures build their own transports aka Meridain, Linn and Naim to mention a few.

It would be great to see a high quality transport kit out there, which would allow a full transport and kit DIY project, with mods and part upgrades available at an affordable price.

I haven't the money at present to upgrade my DAC, which is an upgraded Audio Note DAC 1.1 and Zero transport, but I am very happy it at the moment as it was a huge jump over oversampling units I had owned previously.

Without reading through all of the preceding responses, let me just state (as I have before) that no, contrary to Seandtaylor99, my experience is that a reclocking device will not necessarily render insignificant the differences between transports. Why this is, I cannot tell you with certainty. I can only report that although I find my Monarchy DIP 24/96 to be an effective device for improving the final sound (and anti-jitter box test measurements linked on the Monarchy site seem to indicate that it's one of the more effective such devices at doing its job), it doesn't somehow obliterate or equalize the audible differences between transports, which remain as plain as ever. In fact, it's entirely possible (and seems logical to me) that it actually exposes those differences a bit more clearly, by granting basically the same degree of improvement -- and hence increased resolution -- to each of the sources paired with it (or, if you prefer, to the DAC paired with each of those sources). But whatever the case, I've found that using this otherwise fine unit in no way enables me to consider transport selection as noncritical -- a nice wish, but regrettably, no go en mi casa.
Right, I never said the DIP eliminated jitter, I'm sure it can only reduce it. Its low price shouldn't be held against it, and appears very well made inside (though could be better shielded -- what it radiates makes it necessary to keep it a safe distance away from my phonostage). It's widely regarded as effective with independent test measurements to back it up. It does have iso trannies on the inputs and outputs. The "24/96" version I own uses the CS8427 chip for the PLL, not a SRC, and reclocks. Steve says that a completely effective unit doesn't exist, except maybe his own which isn't for sale yet, so I can't feel too badly about taking advantage of the cost-effective DIP. And if that's true, then it should also be true that there's no box out there which can render the differences between transports unimportant, which was my main point, the question of whether jitter alone is really the whole story aside.
