I immediately noticed this behavior after buying SU-8.@pos , have you noticed this as well?
I bought the Topping D50 DX7s, and in addition to these I bought the latest model SU-8.
But when I knew this behavior it was a shock. The same report is also posted on Amazon.jp.
The reason is to erase the pop noise that occurs when switching to songs with different bit rates and I imagine.
