still waiting for my bottlehead crack to amp up with the 650.
very very disappointed on the hd650 right now, with my auinst rig. I am upgrading from SRH840, and i still feel that teh SRH840 slightly outperform HD650. although it is still less than 50hrs burn in.
hope the sound will improve when it is fully burnt in and the new amp arrive!!
will the dac also improve the sound detail when i listen??
