RE: Tube swapping in Alpha DAC
I don't know about Mullards, but JJ Tesla 12AX7s have made a nice improvement in the sound - not quite as fast as the stock Chinese, but richer and deeper. At $10 per tube from Ned at triodeel.com, its well worth the $20 investment. 
RE: Tube swapping in Alpha DAC
I tried GE 5751s in my Alpha and hated them. The clarity and speed of the Chinese 12AX7s were gone, replaced with a more golden sound, but also much less resolution.
