When using my Wavelength Brick (USB) I am getting a very slight static type of noise at certain times when using the GUI.  This is not an issue in playback of music.  But, for example, when using unattended, right after I press play, while the tracks are being highlighted, there is a slightly audible noise - kind of a hum or ZZZZ sound.  Also when the quality panel slides in or out.  This doesn't happen when I use the Benchmark  DAC1 coax or a Musicstreamer USB.  I can't figure out if the problem is with the Brick or if it is the only one that is able to play back the noise.  This is something I can live with, but I do wish it were not there. Anyone else getting this?

And Peter, I REALLY like the new GUI!.. I can sit in my chair and control everything wih a mouse, including the volume.  I still am using a preamp most of the time though, to have a balance control.  I recently bought a Krell integrated amp to see if my tube amps really were the source of any imbalances, but I get the same just off center signals thorugh it with some recordings, so I am going to need a balance control in any system I finally settle on (as if I will ever finally settle on anything Happy) .  After much experimentation I decided I was more upset by an imbalance in the sound stage than in ultimate resolution.

Hi Glynn,

I think with some experimenting you will find that the Priorities / Core Appointment / Q1 setting will influence this. But maybe don't try to get it out of the way because you will change your SQ (settings) with it ...
In the end it is just your system which can't cope, incurred for by (USB) driver behaviour, no matter the one USB device exhibits it and the other USB device does not. "We" are just using the system at the very limits for the good cause, and you are over it with Attended or when the GUI is still there anyway. You could switch off "Start Engine3 during Conversion" though.

Thanks for the nice words !

I just lifted ground (degrounded?) the power bar that both the computer and DAC were plugged into and that noise is now gone. Will do some more switching to try to figure out what I need to do to ground components and keep this noise out.  It's a good thing I had nothing else to do this evening,
