Due to some issues with my main AMP (right channel is not working), i just used the FX-AUDIO D502BT as a backup amp for my living room (TV, PC and BT connected).
And what should i say, it is surprisngly good. Not the punch of the Advance amp, but not way behind that.
Perfect and easy to setup for me with the Sub out as well.
Normally i just bypass sound settings or EQ, but in case with the FX-AUDIO D502BT is just set to EQ preset no. 4, this works best for my ears and listening style.
5 stars from my side for price efficient small amp.
