(FIXED!) Line in input (3.5 mm/minijack) has constant quiet static noise. Not a big deal, but it is a slight nuisance, especially for quieter music that has moments of silence. I also hear a slight tick in my speakers when changing inputs. I left this comment to help anyone who may experience this.
**Update** I fixed it by plugging my Echo Dot into a different usb power plug. My Anker 4 USB plug was causing static. Fixed now! Just using an old cellphone USB plug. I still hear a slight tick when changing inputs.
This little amp really does sound good, paired with my Q Aqoustics 3020 bookshelf speakers. Didn't realize you can adjust bass and treble, to include about 7 equalizer presets. I don't really like any of the presets and have boosted the bass by about 5 clicks and the treble by 2. All can be done with the remote or by pressing buttons on the amp itself.
Nice binding post speaker terminals, they allow you to plug your banana plugs all the way in. It gives you a satisfying piece of mind.
The remote could be better, a lot better, but that's my only problem. No spark experienced when plugging it in, if you plug the power cable into the amp first and then into the powerstrip/wall. Which I would suppose is the way you are supposed to do it.
