"Do you buy an amp that has a flat response or one that has some kind of sound altering circuit adding coloration to your music? The HA543 addresses and completely solves this paradox. It is as flat as flat can be unaltering the original program material keeping it as true as possible. No coloration, no gimmicks, just absolute pure reproduction of the original material, and it sounds absolutely amazing with a good pair of headphones. Then, when using the HA543’s Enhance switch, coloration circuits are added changing the overall sound characteristics. The end result is an amp that makes the vocals sound more dominant, cymbals much more open and sharpens up the lower frequencies to give the bass very tight detail. There’s a lot more going on than just a simple EQ. It makes the HA543 two headphone amps in one. Want it purist flat? It's got that. Want a headphone amp that has some sound enhancing coloration? No problem." - Bellari
