The retail price of my system (Conditioner + Streamer + DAC + Integrated Amplifier + Speakers) would be about $8,500. Current cabling is an additional $850.
I think the only value in knowing how much others have invested in their systems is to better understand their perspective when it comes things they recommend. A budget component is very different for me compared to someone that has $18,000 or $180,000 in their systems. Sometimes I think well meaning advice is given on this forum that simply miss the mark for the person asking because they are thinking about totally different price points.
