What is the current retail cost of your reference system?

None of your business lol

losers.

mine is somewhere around 6K (new prices) for the one in my living room.

Replacement cost would likely be in the range of $20K-$25K, depending on how you price replacement for items no longer made. Speakers comprise about half of that.  My electronics have lots of DIY upgrades, but would still be near $5K to replace. Most of my wires are either DIY, or basic decent lesser name stuff.  I try not to pay for marketing.  

RRP for current nearest equivalents would be Amp Cayin CS55a, 2 months old, paid AUD$1950, current price AUD$2500. Lindemann Limetree Bridge 1 year old, $1000/ $1500. Denafrips Ares 2, 1 year old,  $1100/ $1400. Audio Physic Sitara 25, 2 years old, cost $3000 (down from $5500) nearest equivalent today a staggering $15000. Rule no. 1, never pay full price. 

Total cost for main system (I do not listen to vinyl) is about $15,000 and cables are another $2,500.
