john.unlimited Posted August 7, 2009 Share Posted August 7, 2009 I am looking to improve the sound stage and transparency of my system, I think the DAC in the next weakest link. The DAC in question is a 707 Super Pro USB. It was major improvement over the stock output of the mini but I feel i am still missing some "air" and "transparency" from the system. All files are Apple Lossless. System as follows: Mac Mini and 707 Super Pro USB DAC at my source B&W 685s Bi-amped Yaqin MC-10 Tube amp with Mullard EL-34s for the midbass (Low Pass passive line level XO) Yaqin MC-10 Tube amp with Tung Sol El-34 for the tweeters (High Pass passive line level XO) All backed up by a B&W ASW750 sub (1000 watt XO at 45hz) Are there any opinions/suggestions on if DAC upgrade will have a noticeable change in overall sound. Im looking at the Proton, Cabrige, CA or a Scott Nixon. Please help. Link to comment
Mr.C Posted August 7, 2009 Share Posted August 7, 2009 When I had B&W 601s3 with a NAD 525 CD player, the upgrade from that to a Simaudio Moon cd-1 was noticeable FWIW. Might be a similar upgrade to the proton. Link to comment
