Customer Reviews
These amps fit my situation perfectly. I use two to drive Lii song f15, and the sub puts to two more A70 monos to drive the Lii song w-21. And the same setup for another system with Lii song fast 8 and w15. I would be happy to send pics. For all those who couldn’t figure out why you added a frequency knob to the front, this is exactly why. Thank you Aiyima
Please Note, I have a very high-end system. I just want to know what is all the hype with these amps, So I purchased Fosi V3 and used it for 3 months and surprised with it’s performance, so I decided to try Aiyima A70 as well. I found Aiyima has very good base control and more powerful compared to V3. The A70 has better sound stage and treble. The table on V3 is too pronounced And over time it fatiguing.
As awaited.
Out of the box a very neutral clean sound.
Used with 16mm Films, mono magnetic and optical tracks. My preference is with the LM4562NA op amp which gives a more mellow sound than the standard op amp. A much improved weighty sound with this small powerful amp. Very high volume possible.
Running two 8 ohm speakers in parallel 4ohm mono load.
Very good construction. They work all day long and are thermally stable. After warm-up time / 30-50 hours / the sound is dynamic and rich in details. A dedicated DAC in a balanced version would be useful. Thank you and best regards.
