PS Audio Digital Link III DAC w/Cullen Circuits Mods (Stage 4). This modded version was bought in May of 2010 from Rick Cullen of Cullen Ciruits. I have barely used this and its not currently seeing much use. I caught the Astronomy bug and going that direction. Has low hours. Awesome DAC (reviews all over the net). Basically brand new with box and all papers. These retail for $799.00 for the unmodded basic version. This is a great deal for the highest modded version available. Smoke-free home. CONUS only. If using PayPal please add 3%. Cash or money orders OK as well. Would be willing to meet up by splitting driving distance. Flat rate of $25.00 shipping (I prefer UPS). Will be shipped in original shipping box from Cullen Circuits. Please email me with any questions. Thanks a lot!
