I have my D2 speaker cables and my D2 phono cable connected to the powerbox. For both cables, the powerbox noticeably lowers noise floor. Music feels & sounds louder but isn’t!

When A/B comparing the speaker cables, the bottom end is tighter and deeper with the powerbox in the signal path. My Stenheim speakers tends to come to live at higher volumes - the powerbox lowers the threshold of that level. 

Hope this helps...

I see that you have Ansuz D2 cables awsome, i plan to purchase D2 full loom and CH L1+X1 + Gryphon Mephisto stereo.

Cheers.

New Ansuz D2 speaker cables and phono cable - both electrically grounded through the Ansuz D2 powerbox. Not sure how it does it, but especially my analog rig has been sucked dry for noise. Someone just turned up the music without touching the volume knob. I never thought my Crystal Cable's were bright, but they are nowhere as deep and full and the Ansuz D2. Remarkable difference!

@oldager ,

You have a phenomenal room and system. And chairs!!

You have some very nice gear.

I have thought of CH Precision for my future build but found that the price to performance ratio is not so good compared to a brand like Aries Cerat.

Nonetheless CH is still my favorite solid state brand.

Even though a second CH A1.5 for a biamped setup or maybe a CH X1 power supply driving the L1/P1 is worth considering.
