For anyone interested I asked Ray how to properly burn in The Intruder and here was his answer:
By connecting the phones to the amp & let it run day & night to get 100+ hours. No worry if it gets warm. Connect it to the charger.
When charger light is Green the battery is fully charged. No ,matter where the gain switch is.
The best you do is connect it to the computer this way both the DAC & the amp will burn at the same time.
I also asked him about the battery charger as to how to know when it was full and his answer was included there also.
I am following his advice now...so far so good. I have it connected up on Windows 7 using Foobar 2000.
