george, while these are both good suggestions
"You have two options to get the best with what you have
.
1:Send your Hattor back and get them to install the optional OPA2134 output buffer in into it, this will allow it then to drive the very low input impedance of the AA or the EP if you still have it.
2: Send the AA back and get a poweramp that has got higher input impedance 33kohm or higher"
I live in Florida so sending the Hattor back is not gonna happen (no telling how long before he turned it around), plus, having seen the insides, I don't think it is upgradeable.
I bought the AA used, so no sending it back either
Fortunately, the combination sounds damned good, certainly good enough to wait it out to get either the AA DCA/PRE (which must be a match) or the Tortuga, assuming it is compatible.
