11/4/13 update: sale suspended
$475 shipped FIRM to USA residents only (no exceptions). (Price is flat, no additional for any fees.) 1st owner since June of this year (bought new from PriceJapan), and condition is 9/10 on the Audiogon scale. All original materials are included - box and all accessories (manual, 1/4" adapter, etc). Less than 20 hours of usage on the headphones (note: have been using these headphones recently and expect to continue to use them until selling, so the hours reported may continue to increase).
Not interested in trades.
I will also include any 1 of the CDs on this page at no extra cost, if desired (note that the average price of these CDs is $30, for any that might still be in production): http://www.crystalsynth.net/cds_audio.html
Note: for those price-checking the AD2KX on PriceJapan (as it fluctuates daily based on the currency exchange rate), the final total cost of exporting to the USA doesn't show up until their "Price Quote Completed" screen, which adds shipping and other fees. Also, the other recent pair that was listed for a really low price was being sold by the 3rd owner. I'm the 1st owner of this unit.
