That's the thread I was think of. Sorry about the confusion.
About the Melos and the HPA-1/2. I like the lush mids and the deep bass the Melos seems to be able to get out of the HP1000. HPA-1/2 doesn't offer that.
I like the idea of using amps that were perpose-built for certain headphones and don't really feel I miss out on anything by not upgrading them.
In any case ( the real reason ), I have my hands in too many pies- my two channels system; my home cinema...$50,000+ later ,there are still a few things I want to sort out before spending money on headphone amps.
