New toy just reached my doors. Fosi Audio BT20A Pro is based on TPA3255 and promises unrivaled sound quality. We'll see about that - it's burning in right now, stay tuned for full review.

Changing opamps is easy, stock ones are NE5532, I've already changed them to 2xOPA627 (I've stockpiled some double sets in DIP8 a few years ago).
Just do rememeber that BT20A Pro needs 2 channel opamps, not single channel ones.

Build quality seems to be top notch, can't wait to give it a proper listening session.
