After spending weeks trying to figure out why I was getting random noise, coming out of my digital equipment, I found the cause. I noticed that it kept coming through, with nearly every op-amp. I figured out my DIP8 socket (on the ES9038 DAC) was faulty. It feels like it has lost all pin tension. The larger op-amps, especially those with lifted DIP8 adapters, tended to fall out of the socket. The review should be out in September. This is mainly due to the number of op-amps involved in the testing process. Which is also why, these sockets are very important.
I also acquired an UpTone Audio IsoRegen, as this is a must for HiFi on a Home-HPC. This totally isolates the USB 2.0 line from the power supply in the computer itself. This is something I had been wanting to get for a while. Got lucky and found one for less than half the normal cost. It looks to be barely used, with the stock power supply, all in great condition.
HL Custom PCB #1: 5V Charger + V1.0 vs. V2.2 Performance Showdown
Update 8/6/20: Grades for the 5V Charger were posted today. I got a 190/200 (95%) on the final project, giving me an A (overall) in Jr Design. If I hadn’t forgotten to show the PCB partially inserted in the enclosure, I would have made a 100! Update 7/30/20: Revision 2.2 arrived in the nick of […]
