Steven,
I must admit that amr support both here in the states and in the UK has been very helpful. The US distributer even offered to send me a preamp on loan untill the DAC was repaired and Owen offered me the iDac2 as well. I purchased an iDAC2 and purifier prior to my upgrade (to use as a stand in in my main system) and was quite pleased. I have them in a second system currently.
