Hello guys! It's been a few / couple years since I built my last budget system for my office here at work. The small little Dayton amp has started giving me fits in terms of scratchy/noise/static when I turn the volume up/down so, I was entertaining the idea of just building me another budget system, just because... well it was fun the last time I did it, and I'll move this one somewhere that it doesn't get used quite as often etc. CURRENT SYSTEM Dayton Audio Bookshelf B652-AIR (Pair) Dayton DTA-1 Amp Dayton Audio Sub-1000 Powered Sub Looking to keep the newer/upgraded version of a system in the $500 range. Let me know what you guys think, my hat is in my hand here as well, I'm by no means an audiophile, just someone who listens to music nearly the entire 9 hours I am here at work and enjoy decent sounding equipment. If a sub upgrade isn't possible at that price point, it gets loud enough to annoy the people downstairs so... I guess I could keep it or work around it, but if another $100 gets me a bigger/better sub, looks talk it out. Thank you guys so much!
