Heyo! Just picked up a uturn orbit WITHOUT a built in preamp. I had a digital amp and bookshelf speakers already and though that would be enough. I was wrong. Sound is super quiet. I have been interested in these speakers (Audio Engine A5+) but not sure if I need additional hardware on top of those built in speakers to make the music happen. I've been reading that you need preamp and amp and then speakers but it seems like there's all sorts of "well not if you have this". Any guidance is greatly appreciated!
