Why is the USB connection at the front. Would the rear not be more practical? Otherwise a very nice product.

Very interested in amp with USB on rear. I will send you an email.

Is optical SP-DIF possible instead of Coax?


Thanks.

David.

Hi,

I'm studying the SigmaStudio graph you post earlier but it's not clear.

Can you post a high resolution picture of the graph.

Thank you
