I just recently upgraded my old HP 15 AMD A6 driven laptop with a new Dell Inspiron 3000 series with an intel core i5. I was not looking for an upgrade in sound quality of my office system, but a faster computer. I just could not resist the $350 price tag. Don't tell my wife ! I started loading up the programs I wanted on the new one. This is my setup in the office now, Dell laptop>Peachtree Dac*itX DAC>Primaluna ProLogue One integrated tube amp>Core 2 DIY speakers. I was very happy with the sound with my HP Laptop and it was set up the same way as the Dell is. I use Windows 10 on both computers and JRiver version 19 for playback on both. I made sure to use the same Peachtree USB driver for each computer (double checked to make sure they were the same). Audio output was set to Peachtree WASAPI on both computers in JRiver. I would expect the two computers to sound basically the same. However, the SQ on the Dell is so much better that its not even funny. Any thoughts on why this is ? The HP uses a AMD High Definition or a Realteak High Definition audio driver. The Dell uses a Realteak Driver for audio, but I was under the impression that these drivers were by passed when you went USB digital out to an external DAC. Is this a correct assumption ? Any thoughts would be appreciated. Thanks in advance, Matt

It's unusual. It could be that the power on the old HP was very bad and it was leaking in to the USB output somehow causing jitter. Or simply that the USB ports themselves were not good? I don't know. It shouldn't really have an effect.
