Several years ago I had great luck with an HP Envy. It served me well for nearly 5 years which is really good for a PC. However when I upgraded to a more recent model, it was a dud, all sorts of problems with running low on memory (despite doubling the RAM and processing power of the older machine), static and other issues through my USB DAC. I thought it was just a fluke, so I foolishly got another Envy in Aug 2016, this one with an Intel Core i7-6700, 12GB RAM, 2TB HD, etc. It sucks even worse. I think part of the issue is that as my music collection grows to over 6TB, between my MediaMonkey and Logitech Media Server reindexing nearly every day, it's left gasping for memory and I need to reboot it multiple times a day or it starts degrading the signal sent through USB to my DAC in the form of static. Also now my LMS is making horrible noise in between songs. I'm going to try out Roon for my multi-room music management, and read that it's recommended to have a fast SSD drive, so I probably need to upgrade either way. I DO NOT want to build my own. I tried that once and it was the worst three months of my life. I hate that stuff, hate troubleshooting. I just want something that works. I don't want a Mac either. Normally I don't pay more than $800 since the lifespan is so short on these, but will go higher this time if needed. Requirements, minimum 4 USB3, decent CD drive to rip audio (horizontal, not vertical), 250-500GB SSD, Quad Core i7, 16GB RAM. I wonder if there are any that have two sets of USBs on different buses? It's been mentioned that can create problems when it's accessing an 8TB external drive for the music files, then outputting audio via USB on same bus.
