I just recieved my AIYIMA 07 Pro.Just checked it with below stuff.

Power Supply - 32V/5A
Input Mode-Bluetooth
Signal Source - Android Phone Bluetooth (You Tube & Spotify)
Speakers - Philips bookshelf speakers (BTD7170). Size 5.25" woofers & Dome Tweeters.

Pros-
*Very good BASS performance against AIYIMA A03 (TPA3116D2 based amp). I just put it to one O'clock position.Good BASS.
*Very Good Construction.
*Very Good Volume
*Very Smooth Controllers

Cons-
*The treble boost is somewhat low. (The Treble Knob I keep turning fully ON but still the trebles are very low)
*Right side channel is bit louder than channel left.

I like to change its OPAMPs & see how it performs..Has anyone tried chinese A grade OPAMPS like LM4562, OPA2604 (Not the original Texas/ Burr Brown Ones)...!!

Thanks

Doesn’t sound normal, normally you will get 6db+ gain on tone controls.
Channel imbalance also isn’t normal.
I have 2 x A07 Pro and none of them has any issues.
