@npdang Just reading about your experience With the HD Plex supply. If I can give you some advice it would be to ditch the cables you received from HP Plex and and replace them with better ones. I now have silver core cables feeding my J Cat cards and it is a huge difference,give it a try you will be pleasantly surprised.
JCAT Femto USB Card
I would like bring awareness to something that has drastically changed my computer audio experience: the JCAT Femto USB card.
The USB was very easy to install specially since Win 10 Pro recognizes the card without installing a driver - true plug-n-play. I was initially unimpressed with the sound and decided to burn in the card by continuously feeding signal through it for a week. OK, now I'm impressed. The imaging is so surefooted/solid and are emerging from a black background that I'm now experiencing my system in a way I have not experienced before. Even bass and midbass produces a solid image. The soundstage has become well layered and has grown a bit in height possibly due to increased midrange clarity. I thought my computer setup was excellent which is why I did not anticipate such a great improvement. My system is very revealing and all components have been modified with upgrades such as capacitors, resistors, diodes, fuse swaps, etc. This upgrade is a large step toward realism and allows my system to show off it's capabilities. The JCAT USB Femto card is highly recommended.
I ordered from the highend-audiopc website and had a positive purchasing experience.
It's good to see new products in the small PC audio market. Hopefully, in time, we'll see better competition and prices.
