I purchased your AIO200 product through Amazon.com. The delivery was fast and professional.
However, initial tests reveal serious flaws in this product. First of all, after connecting two different types of speakers, it turned out that the sound level was very low. A comparison with the WIIM AMP PRO and the S.M.S.L. AS400 amplifier revealed a very low output power level.... It simply sounds quiet even when set to maximum power.... and supposedly it has as much as 100W at 8Ω. Another problem is the maximum bass boost (5dB), which caused very noticeable distortion when listening to the album SAVAGE ETERNITY (SPOTIFY) very noticeable distortion occurs; you can hear it even when the HIFIMAN HE400SE headphones are plugged in.
Sometimes you can hear crackling and pops through the speakers (METALLICA – “To Live Is To Die”)………..
If this is how it’s supposed to sound, it’s a waste of money.....
