The A20h is constructed in the same way as the A10h, it only has twice the output stage of the A10h.Yep, sorry. There could be something with it. I've not seen anything from Sabaj/SMSL about it, nor have I seen any A10h disaster posts online, that's all I've got. I myself have the A20h and I've zero issues with it, but don't own the A10h..
For balanced operation, you could also use two A10hs (one for the right and one for the left), then you would have practically (almost) the same as the A20h, only with better channel separation
