I also don’t like AMP11 and consider it the worst amplifier IMHO, but AMP14 is my favorite amplifier. To me it doesn't look like AMP11, it's a cross between the detailed AMP12 and the tube and massive AMP13. IMHO

I rolled back the firmware using 660 tools to 2.03, and installed 2.04 over the air through the settings

I've been sitting on firmware 2.04 all day and have no desire to update further. The sound has become more accurate, biting, percussive and detailed (probably superior to 2.06 and even more so 2.07). I love it.

I rebooted several times and reset the device. As a result, I rolled back to 2.03 via 660 Tool and, surprisingly, AMP14 worked! BUT! it works at high gain at a volume of 54/63 (Ibasso IT05), so I will update to 2.04 (from this update AMP14 support is announced). And then let's see the result.

Hi all! Has anyone tried rolling back the firmware to 2.03 and checking the functionality of AMP14? (from memory, the sound for me personally on this firmware was the best, but AMP14 came out much later) Today I updated the firmware from 2.06 to 2.07 and it is terrible, the sound is not my thing...
