Been heading down the seemingly endless road of tweaking…! I thought I’d share some of the things that seem to have made a difference, some of which are a bit counterintuitive, in rough order:
-
Plugging the amplifier into the wall socket instead of through my isotek power board. I’m not sure it was coping with the power draw, particularly with loud and complex passages. Perhaps a serious power conditioner would be better. McIntosh 6700 amplifier;
-
Connecting my dac through USB instead of ethernet. Perfect wave DAC with Bridge 2. The direct connection seems better than going through a router etc;
-
Linear power supply to my NUC - Teddy Pardo;
-
USB cables, Audioquest Carbon from NUC to DAC;
-
XLR from DAC to amplifier.
1 and 2 made a very big difference - unfortunately, they were also the last to occur to me… The others are more open to question. Too embarrassed to list the failures, although most are not complete fails so much as wrong forks in the road.
Be interested in everyone’s thoughts.
Cheers
