Experience with Audio Alchemy DDS pro transport
Since my PS Audio transport has quit breathing I have to buy another transport. I'm thinking of buying the Audio Alchemy DDS pro + DDS PSU pro power supply. It'll be combined with an Northstar Design Model 192 DAC with either the AES/EBU connection or the I2S connection. Does anybody have any experience with this transport?
