Thanks Sam. Bill - give it a rest.

USB to Ayre and to Scarlatti when using upsampler, otherwise optical out from Mac Mini.

You preferred optical out to the Berkeley over USB to the other two?

Yes, very much so.

Recent coverage of USB DACs might have left the impression that the new approaches to doing USB well are automatically superior to older means of connection. I do urge using your ears, and your system, to come to a conclusion on that topic yourself. It certainly isn't my experience.
