Pc to DAC Configuration

Hello all,
Presently, my DAC is located next to my IMac Pc.From there I'm running 30'
inter connect cable to the preamp which is residing on the main audio rack.
My question is: Would it be sonically beneficial to move the DAC back to main rig , so I can use my high end audio cable and thus eliminate r f distortion
that's associated with such long runs?
My proposed configuration would be: IMac>12' USB>Bel Canto 24/96 USB Link>12'S/PDIF>DAC.
Will this configuration be better than my current set up?
Thanks all of you for your response.
Regards,
Rod

The USB interface on the BelCanto is Adaptive, not Async, so it is sensitive to jitter. I had a similar interface (CEntrance) in my older products. Need to use a good quality 1-1.5m cable.

If you used a newer async USB converter, then you could go with a cheap 16-foot USB cable and shorten your analog interconnect. This would be an improvement in jitter and minimize analog degradation and it would support 176.4 as well as 192.

It is possible to build your own USB cable and get 10m length to work. I have not tried it myself, but customers have. See:
