having owned the Andras, their only real deficiency (to me) was the midrange, which lacked a bit of speed and transparency (the bass and treble left little to be desired).
other than that, finding something significantly better is going to be a real chore, especially considering their musicality, especially on strings and piano. i eventually replaced them with von schweikerts, which do possess a state-of-the-art midrange driver. but even the VS's, again, IMHO, bear a close resemblance to the eggleston sound, just quicker and more open. however, i'm a bit surprised you didn't enjoy listening to the andra's alot more. of course i confess to spending a small fortune on transparent wire, which took the speakers to a whole new level, with deep bass and a big 3-D stage.
