I did buy a solid silver AQ digital cable...used...for something like 60 bucks. I know that's extreme but hey...I can afford it.
What is the current retail cost of your reference system?
It would be interesting to share this as I am not sure some of us understand how decisions are made within the framework of cost and resolution. Please avoid used prices as that muddys the water significantly. Also cabling costs would be revealing as well if willing to share.
