I have pretty much a stock Dell XPS with a gpu swap. I got it barely used off Facebook marketplace and I cant seem to find how old it really is but it’s quite a good computer and most likely quite new as well. Can’t say how big of an effect this stuff can have on the sound since I’m pretty new to the hobby and haven’t tested a whole lot of things, but it’s probably worth testing how well it sounds with your pc before investing in a quality amp. But then again if you know you’ll need one in the future, might as well get it now, depends on your situation I guess!

I’ve never tried my pair with an amp/dac but my laptop/pc seem to drive them fine. I have heard that you’ll get the best out of them with an amp though, but shouldn’t be a big worry.
