Yup, 10K is probably it. I run the Weiss 501 4 channel. Would agree that a very good digital cable is essential. I run the 75 ohm Jorma after using the Nordost 1. It really is that good.
Understand the Weiss 204 to be a stripped down version of the Weiss 501 2 channel which probably gets you there too.
My combination gives the "sounds of performance" such as breathing, fingering on acoustic guitar strings, distinct sounds of piano foot pedal work and of course Oscar and others humming while playing. Best of luck on your quest.
