Title: Beware of the monitor power plug position Post by: CoenP on March 21, 2017, 12:28:27 am Hi,
After a small interior-painter-audio-system-wintersleep I've got it in position again. And guess what? It sounded like total sh*t. Anemic, foggy, sharp and lethally uninteresting. I ran all the connections and system details, but they seemed identical to the situation before the paint job. I took foto's and all to be sure. Then I realized I had moved the monitor next to the PC since the KVM cable had some bad mouse and keyboard contacts. Of course this went along with a new power outlet. Naturally I took a power search screwdriver (the one with the orange neon light in it that glows on the hot pin) and voila an inconsistency: the light glowed opposite to the marking on the plug. Flipping the plug did nothing short of spectacular good things for the sound. The life is back as are the individual instruments and their dynamics. This is some 'detail' to pay attention to and totally free to boot! Now I would be lying if I said that the sound is the best I ever heard, that would take definitely a different and more capable amplifier and maybe some of Peter's new tweaks that are in the production pipeline. regards, Coen Title: Re: Beware of the monitor power plug position Post by: manisandher on March 21, 2017, 06:50:06 am Have you tried using an RDC connection and taking the video card out of the audio PC? Assuming you can get a LAN cable to the audio PC, of course.

With my old PC removing the SC was devastating to SQ, probably because in the background the on-chip GPU took over. As I understand the XXHE PC does not have a processor with an on board GPU (Xeon). I will try this, hopefully the monitor will have less or no influence when connected to another PC... regards, Coen Title: Re: Beware of the monitor power plug position Post by: PeterSt on March 21, 2017, 09:45:19 am FYI :
My Audio PC is just headless (no monitor and video card removed). The related Music Server PC has a monitor connected but I disconnect the monitor from the mains (there's a switch in the power line of it). This leaves my tablet for control. Any monitor is of the utmost negative influence and can always be easily measured on the DAC output. Always (91KHz or so). Peter |
