Granted, the FX Audio will not run a pair of speakers - but it is light years above the Dayton as a headphone amp. Currently playing Mark Knopfler's excellent "Privateering" from HD Tracks through the Akai cans Nick steered us to.
I have played this album many times through my Sennheiser/DTA combo before and this cheap Akai/FX Audio are on par with my cheap Sennheiser. Keep in mind my Senn's are an entry level model, I forget which. I swapped gear around a few times to be sure, but I do prefer the Aka/FX combo.
Anyways, I have spent far more on way shittier SQ.
