Probably not what you’re looking for, but I’ve been really happy with my JBL 306Ps for the last three years. They sound great and can get way louder than I’ll ever really need. Sometimes I wish I went for the 308s for more low end but like 90% of the time I’m satisfied.

Hope you can get your issue resolved. Audio issues are so incredibly annoying.

It can complicate things, but there are small cases out there with larger/more powerful components in mind. There are good designs and bad, same with any size, just have to keep your component choices in mind. I’m a big fan of ITX builds with high end hardware. At some point it becomes sort of a puzzle, balancing your components for size, heat output, and air movement. Not worth the hassle for some but I find it fun.

As others have said, AM5 will give you DDR5 and PCIe 5 options for some future proofing, but the 5800X3D is still an excellent CPU and would save you some money in the short run. If you go AM4 I wouldn’t bother with anything but the 5800X3D unless you’re on a really tight budget, which doesn’t seem to be the case.

And yes, rebar is a thing now. Improvements vary but it’s there and works.
