Zbub, thanks for the question and your interest. I’ve personally done the upgrade to my C1 several months ago and love the improvements. The overall presentation has become more open, richer, more extended at both ends of the spectrum. I’m biased of course! Read the review of Marshall Nack from Positive feedback.

Zbub, I never thought the original D1/C1/CH-Link combination bright so its hard for me to answer your question. The HD platform improved the performance of our digital front-end to be sure and that includes the high frequency presentation. I hear it as more open now. I don’t consider D1/C1/HD-Link the least bit bright. If you write me a note at my email listed below, and let me know where you live, you might be able to visit one of our dealers and hear the D1/C1/HD-Link combination.

The HD upgrade consists of an upgraded digital output card for the D1 transport, a digital input card for the C1 DAC, and a new HD-Link Cable. In the C1, we have implemented an improved upsampling algorithm and digital filter which that together are partly responsible for the improvements. These upgrades can be done by a dealer at your house in a matter of an hour for the C1/D1 and new HD-Link cable.
So the new C1 digital input card can give improvement also to C1 usb input users too?
Hi Everyone. The HD upgrade to the C1 improves all digital inputs. The improved upsampling algorithm and digital filter are used on all digital inputs; from the D1 via HD-Link, on USB, on ethernet, on AES/EBU, etc.
