Excellent Quality!

I have this set up to run my front tower speakers connected to my AV receiver. Makes them sound much clearer than my high end Denon. Very good low's, mid's and high's!!! Plenty of power. Highly recommend!

Great sound, but beware of the 10A PSU

The standard unit out of the box exhibits zero noise in the background, especially with the XLR input. When I plug in the upgraded 10A PSU, there is a whooshing sound that appears, and it is very noticeable. I traced it down to a large amount of ground current in the AC ground line, due to either a fault within the unit, or bad design. If you disconnect the ground pin, the noise goes away ! I am not sure it is the safe thing to do, and am thinking of ways to preserve the ground for faults, while filtering out the noise, but I have no time for that now.

Good sound but….

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.

Compact and very good sound!

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
