I've never heard any improvements with PC's but do own some nice ones in the system.  For me it has always been IC's and SC's that impact the sound.

If you happen to have a combination of transport and an external DAC the digital cable (BNC or RCA) has also the most impact on sound. 

I don't presently have separates, but have been looking into it.  How is it that a short digital interconnect can have a drastic effect upon the sound?  I can see if it was an IC that was technically deficient in some parameter, but this is just a digital signal, and not analog audio.  My understanding has been that as long as the cable is of solid 75 ohm impedance with wide bandwidth, the digital waveforms are quite happy to pass through unaltered. 

Jitter has usually been the main issue between transport and processor.  Are some cables better at jitter rejection?  If not, then what is the technical reason some short digital ICs are supposed to be better, assuming they all are of 75 ohms and have a wide bandwidth?

if you are using a cdp as a transport, does it matter if the pc is just ok or does it also benefit from better pc's?
i ask this as i have a battery powered dac and am using a sub $100 (for digital) power cord on my transport. think signal cable magic digital pc only made by element cables.

Housteau,

Do you know or have experienced any of true 75Ohm short digital cable that have wide bandwith? Let me know. Thanks.

I honestly do not know, not having measured any myself.  Are you saying that the variability within these two parameters is then the key to these differences?
