What is the best BNC Digital Cable under $4,000?

Ban that person!

I had been using Blackcat Silverstar II for 4 months.

It has nice details. focus and decent soundstage but with slight hard edges.

Sablon Panetta BNC  has all the good things of Silverstar II with refined treble.

I've heard the Black Cat TRON users say that it has a deeper soundstage than the SilverStar 75 or Digit 75.  Has anyone here used the Synergistic Research Digital BNC cables before?

i use my own brand

the secret sauce?
you get bit perfect 1s and 0s
and a few random select 2s to warm it up
a rare 3 to keep it exciting

If you want deeper soundstage, you had better upgrade to Dave.

The difference made by digital cable is subtle not huge.

But Dave will impress you.

I replaced Zenwave D4 with Sablon Panetta BNC half hour ago.

Thus I am using two Sablon Panetta BNC upfront.

Then it sound more refined with clear and deeper soundstage.

I think it is a waste of money spending on expensive digital cables costing 1K or more on each.

You had better spend the money on upgrade of DAC or source like decent music server or CD Transport.
