For people using USB powered DAC's, I talked to Dave Elledge and had him make me a DISCREET USB cable for my setup. This cable eliminates the 5V power line from the cable for use with powed USB devices like the M2Tech Evo. Helps to lower the noise floor of the MS-1 setup.
I also had Dave make me a DISCREET USB cable powered from my BatteryBUSS. Used this with a DAC that is USB powered and the noise floor droped a lot!
Have asked Dave to make me another DISCREET USB cable for the MS-1 that shipped to the ACA gathering in NJ. He will ship it to shadowlight once it is built for the listening session. This works very well with the MS-1, CI Audio Transient MKII USB DAC and the CI Audio external power supply. I tried it here with my setup.
