I've added Walsh-type 360-degree super tweeters to my VMPS RM2's (came with 2 spiral ribbons per speaker).
But the best thing by far was to add the Lyngdorf DPA-1 digital preamp with RoomPerfect room correction. It basically transformed my listening room quite close to "perfect". And it gave me several great subtle voicing options at the push of a button that allow any recording to sound its best. I'm like a kid in a candy shop with this thing!
It took the place of a very good tube preamp and the Wyred 4 Sound DAC-2, plus it has the digital room correction and a crossover and outputs for separate woofers if you need it.
