Review: I'm currently using two of the Aiyima A70 mono amps that work great when paired with Dynasty ProAduio PX2 pre-amp. I wasn't able to run amps at full bore due to sound was too loud. No joke. Previously, I was using a Douk tube preamp which until it went out within 3 weeks of use. I thought sounded good until I decided to paired with the PX2 preamp, and they work really together. The Aiyima is clear and articulate as any full size amp I've had used before. I'm talking about NAD, Adcom, Hafler or Yamaha.And I had them cranked to just over 1/2 where the sound was too loud with no distortion or breakup. No Bluetooth with this amp. I was surprised at the headroom given, and the attack time was spot on. I'm not joking. But how long with these last, no idea. I got these new on sale, one for $118 and the other was $85. I highly recommend, will fill a room 18'x15' with no issues and volume to spare. So far a strong 4.5 amp!
