Arrived very quickly. This amp is very powerful but definitely not Hi-Fi, it lacks clarity on the high frequencies (treble). i tried with Bower & Wilkins 602s and JVC satellite speakers but didn't get any satisfactory reproduction of high frequencies. Initially I would have given a higher rating taking into account the price - but for example, I have a 20€ TG118 Bluetooth speaker which has better treble, and that price includes the housing, speakers, Li-Ion battery, charging circuit, TF card reader, etc. If power is more important than high fidelity - go for it. Personally I'll use this to drive a sub-woofer and continue searching for an amp with better clarity on the high frequencies.
Very good
