It is a pathetic solution that the manufacturer deletes the type designation of the cheap part. It doesn't even take responsibility for the decision to use a low-quality component in its product.
SMSL-Mandy is also gone, maybe she never existed. (S)He's on vacation, that's why she doesn't respond to my inquiry.

Thanks for the advice on op amps!
Have you changed opas in the D300 yourself? Have you done any tuning?

I tried the AD8397 in place of the subtractor circuit, it had an amazing sound, but it was terribly hot. In the I/V stage, the OPA1656s make great music!

But in the subtractive position, I hear their sound as "thin, disembodied". Of course, this statement applies to my current sound system
