I buy new stuff and never get rid of the old stuff.
PerfectWave DAC, black, very good condition, $980. (If you buy the upgrade board, it’s a great way to get DSD performance at about 2/3 the price for a new, retail DSD). Shipping included to lower 48.
Also available: Cary Audio DMS-600 network player, black, excellent condition, $3,890.
