Should be ok from a power standpoint. But driving the LCD-2 and especially the LCD-3s to their full potential really means more than just power. There's also different types of amps, Class A, AB, D and the way they deliver power is different. There's also the ability to supply enough current (which orthos love) when needed.
Its about the entire chain. Source --> DAC --> Amp --> Headphones. We'll leave cables out of this discussion
. But for the "Summit-fi" level of headphones (like the LCD-2/3 or HD-800s) to really sound their best and let you hear what they can really do, one really has to ensure that the entire chain optimized. 


















thanks to all the replys
Seriously though, you might wait till later next week when all the early adopter, cough cough Raven, get them in and maybe you could check out what this combo actually sounds like.
