Thanks.. I think I want to try the opa627's. I can get a pair of the AU' surface mounts for $20 shipped + brown dog adapters for a couple dollars extra. (anybody wanna sell me one for $5 shipped?
I don't want to pay $12 for a pack of 5 >_>)
It's a tad expensive, but there seems to good-sized base of people who agree that it sounds better than all the other alternatives.
