I am planning to purchase the Fostex HP-P1 (which will be my first portable DAC/amp) after watching your video review. The question is, how does the M-80 perform with the HP-P1? The M-80 seems like a very interesting product, but do you think it matches well with the HP-P1?
Also, it's a bit off-topic, but are there any advantages of using the iPod touch or the iPhone over the iPod classic in a portable rig?
HP-P1 + M-80 is an amazing combo IMO. more results soon, the XM6 is my favorite thus far, however with M-80.
