Hello all, I've been playing with the m9xx since yesterday, my thoughts are that
The grace 9mxx sounds really sweet and its quality shows in an out. I agree
With a few here. I use both usb cables for greater performance. I'm leaving the unit
On all the time until it fully breaks in! I like filter 3 the best. It sounds a bit more
Warmer and natural to me. The power brick elevates it to another level. I use cardas
Caps on the unused rca plugs to lower the floor noise, I think it helps, but my Shure 846/ moon silver dragons and Westone ES5/ Alo audio sxc-24! Among others show
That there is a bit of noise and buzz riding or living in the unit. Maybe it will disappear
With time. I have experienced this before with portables. Better cables might give
Better results altogether, we shall see.
