Retail for the main system $50.5K, and for the office & patio systems combined $4.1k. However, I would never pay retail, this hobby way too expensive, far too fast, especially for those touched with OCD. Most of my components were purchased from dealers, pre-owned as trade-in's, some from audiogon and USaudiomart, and some new. As described by @ghdprentice in other threads, I purchased components of similar quality after alot of research, trial and exchange. This way I was able to achieve a system with relatively good synergy. Only item lacking at the moment are my speakers which are due for an upgrade.
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.
