IMHO a top of the line set of Monitors is just about as good as it will be to the real sound of the instrument. I used to have a set of HR824 Mackies, and they were superb and THX certified.
Sold them when I sold the PA2XPRO...
Thats the answer, near field monitors, but only when placed on the right spot.. with you in the centerspot.. the rest of the room gets an acceptable sound quallity at best... they are not meant to play in the open... but sameas with headsets, to be used when recording..
