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.

Zaikes ... I also use a Monarchy DIP. I wasn't critcizing your choice. It's a great product for the price.

Jsadurni, "brute force and ignorance" is a term for using over-specified products to achieve an end. I was not accusing you of being ignorant.

"my main point, the question of whether jitter alone is really the whole story aside."

Zaikesman puts it correctly, our ears are telling us jitter is not the whole story, maybe we have to unwrap the whole "DNA" chain before we know for certain, its good to have people like Alex and Steve looking into this.

Seandtaylor: cheers man :)

Still waiting for Alex's response: If it's not jitter what is it????

DSP??

I dont know about ESP, but my jitterous transport is scary!!!

Maybe Saendtaylor99 is on to it with the input signal:
this is from the Attraction DAC: "The high integration of unique features was achieved by the development of a special digital receiver-chip (Altmann R16)."

"The digital input signals are recovered with extremely low jitter as they are generated by custom made voltage-controlled crystal-oscillators (VCXOs) and employ the UPCI (Ultra Precision Clock Injection) technology."

"A switchable JISCO-function (Jitter Scrambling Decorrelator) further increases sound quality as jitter-components from the DVD-A or CD player are decorrelated before being ultra-precision-filtered."

very interesting reading...

I havent heard the DAC but it has rave reviews, and its really nothing fancy, a nonos DAC and an opamp...yes battery power supply.

Steve do you know which other dacs use this technology?

Best,
