As I understand it, this "moderately priced" system comes in around $15,000 without cables and just one music source.
In this day and age? What defines a moderately priced system?? As a country, we have been trying to define middle-class. $250,000?
So add in moderately priced cabling and a moderately priced turntable. Can we say safely say $20,000?
When I add up the retail of my system, it's up around $15,000 for everything, though I often bought used, or at a discount. But my system includes a turntable, two cartridges, and an outboard phono stage, not to mention a very good CD player. My speakers are very, shall I say, moderately priced, having retailed in the 1990s around $1500. But in certain contexts, those are lower priced speakers (and while they're extraordinary for the money, they're the relative weak link in my system, though they were heartily approved of by two different audiophile reviewers).
But what would probably come out to a $20,000 may or not seem moderately priced, depending on the eyes of the beholder.
