Information on Acoustat 2plus2 speaker upgrades.

I have Acoustat 2plus2 speakers and have really enjoyed them. Ive has Sound Lab M1 and A3s, Martin Logan CLSs, Quest, Magnepan TYmpanis and alot of other planar and electrostatic speakers. Presently I have the 2plus2s and Yankee planars. My listening room is 20x30x12 and I have a wonderful wife and son who doesnt mind my speaker systems. I want to know if anybody does upgrade work on the 2plus2s. Also does anybody know how to make them look better than they do. Such as bases or wood rails,etc. Im using Threshold SA-2 monoblocks, the FET-9 preamp. I have a Roksan Radius 5 table and a Esoteric transport with a Meridian DAC.
