All those of you on this thread who may be curious about NOS sound have a last chance to pick up an HM-603S for cheap here in China:

Just one example - there are several other Taobao sellers. The 603S is basically a 601 with the amplifier section of the 603 (no USB DAC capability, but enough power to drive full-size cans).
It seems that they are offloading their last stocks of TDA1543s.
I do feel that it sounds slightly better than the HM-601LE (enjoying mine through Dunu DNKs as I write this).
I will miss cheap and easy access to all this Chinese gear when I go back to Europe in a couple of weeks!
