Headphoneus Supremus
I'm planning to get some Mr. Speakers Alpha Dogs, and several people were saying that to drive them to their best possible sound would really take something with at least 1000mW output into 32ohms. And yes, I will want to be able to take them places and use them on-the-go. Not for walking around though, of course, I know they're too big and heavy for that.
Are those people "wrong," would I be fine driving planar headphones like the Alpha Dogs from something that does 800mW output into 32ohms?
Yes they are wrong. You will be able to drive the Alpha Dogs just fine from FiiO's 880mW@32 Ohm. For example with the LCD-2 (similar specs, less efficient) I never really have the dial over 1/2 volume on the e12 in low gain. I doubt you'd ever use all the power available on the Cayin C5 or the e12.
