Thanks guys for all the suggestions. This is the high end audio section and high end audio is expensive. Seems like the best value AMP/DAC for the LCD-X at this time is the Mjolnir and Gungnir. In addition to what I paid for the LCD-X I now will have to pay another $1600. Any suggestions on how to hide this expense from my wife? She will kill me if she finds out how much I spent.
Sounds like she's due for a trip to a designer store or a jewelry store :)
I'll throw in the Bryston BHA-1 or the Naim DAC-V1 (as an all-in-one) as alternate amps. They both drive the LCD-X very well. When I'm using the Bryston, I'm usually using the PeachTree DAC-iTX.
