I never really see any mention of my onboard audio, soudmax integrated digital hd audio, but it definitely doesn't sound that great unless I use srs iwow audio sandbox, software that manipulates the sound. Maybe it doesn't keep the music true to the source, but from a relatively less critical listening perspective it sounds 2x more musical to my ears. Not quite at the level of the itouch 4th, but it covers a lot of ground. But gabjuasfijwee if you do move up to the udac-2 let me know how it compares to your portable media player's SQ
And Ham Sandwich I understand that the bx5a are barely entry level studio monitors so they wouldn't compare to the m-audio's cx series or similarly priced products, but if we're just listening to already released music, not mixing or producing, my understanding was tracks would more likely sound 'musical' from a listener's perspective by using less expensive studio speakers?
