the axim distorts with every player ive tried at full volume....note in the preamp i have it a bit lower than normal...with this setting i can have the main volume one step below full and get good clarity..
the main thing i noticed with withmp3 is i could get a better bass out of it before it distorted...
the headphones i use are actually cheap panasonic headphones..for what ever reason, they have an awesome sound compared to more expensive sonys etc i tried with it...
