Geez, this thread has been around forever, and my post from 2002 of $23,000 is just about half of what it is today, $45,133 more or less.
Many of the same components from then are still in place, but some have been modified at a cost, substantially upgraded, or replaced altogether. Also, inflation has made all the still-available stuff a LOT more expensive, especially cables -- which is about all I own that IS still in production today! (plus my headphones and some accessories; speakers and tuner just recently discontinued)
Go to my virtual system page (about the only thing I keep up to date here, for my own records) and see how that $44,133 is divvied up.
This is *retail* price: the MSRP of the components today or when last available. Thanks to audiogon and keeping some older (and therefore less-expensive) units, my *actual* price paid over the years is substantially less.
