This is replacing Aiyima T4 amplifier that I totally enjoyed. It was A hybrid amp with a tube front end. As I was dusting my shelf the power socket bit the dust. Anyway I bought this one to replace. I personally think the BT20A runs clearer and better sounding. The Aiyima was no slouch and sounded great to.
I am using this amp for my tv. I plug the chord from headphone jack to amp. Speakers are JBL's Northridge E-20 speakers. It runs them just fine. Would like to mention that switching to rca inputs to Bluetooth is great. It does it by its self. Just look for it's legend on my device and it connects automatically. Love it. Do not have to move a switch. Great buy.

Product looks premium and its worth it. It gave a new life to my old speakers. Sound is also great and easy to install. Thank you Fosi Audio.

I was impressed by the performance of this tiny amplifier. I connect this to my Polk Audio RTi4 bookshelf speaker and it is almost noiseless when using bluetooth, though I haven't tried using my turntable as it is currently connected to my high-end amplifier. But will try in one of these days and update my review by then.
For now I am very satisfied with how this small beast perform.

quick shipping. easy setup. sounds great. super happy with this. only complaint is I want to use it for blue tooth sound (music) and to listen to movies through my TV and I have to plug in / unplug the banana connectors to switch between outputs - no switch to toggle between them. So kind of a pain, but I can still make it work.
