My main system (CDs, ripped files and streaming) about $15K, including $2K for cables. A second system (streaming only) about $4500 including $500 for cables.
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.
