Customer Reviews
The sound is very good, bud i have problems by using my phono input with my streaming preamp. (Wiim Ultra) i hear a hiss (different sound with missing ground). With my old power amp „Rotel RB-06“ no problems. I switch all the cables. I can not remove the problem with the A70. My guess is the Aiyima 10A/48V power supply unit is scattering a noise in to the phono signal.
Both RCA and XLR inputs and plenty of power. According to tests I seen it delivers 90W in 8ohm*2 with good PSU. Used a MeanWell 90W AC/DC adapter because of their very high quality and Safety approvals.
Good amp, paired it with a wiim pro plus

Wow, for the price it's beyond expertations. It's literally now background noise it's totaly quiet when not playing any music, even when the volume is set to maximum. It delivers good amount of power, I have not been driving it so hard, but it's obvius that I've got enough headroom when driving my GamuT phi 3 bookshelf speakers to normal and a bit louder than normal listening levels.
I've got the 10A power supply for the amp.
