I run the Conductor with a pair of Senns hd800 i open my player after i open my Conductor. I check in my player preferences if its set to ASIO ,BURSON USB ASYNCHRONIOUS MODE in my case i put some classical on ,and it will warm up eventually thats it i dont have any problem and it sounds great. Pricewize i paid $1500.00 shipping included here in Canada
So no driver problems related to the usb ? what OS are you running?
i use mainly OSX 10.7 and 10.8.
