I had the 99.26s on home demo a couple of years ago when I was auditioning kit for my system. I suspect they're better for HT than for stereo duties, at least to my ears. At the time I short listed the Vienna Acoustics Haydn Grand SE and Linn Majik 109 over the XTZs, and eventually wound up with the Linns. I thought they were more refined and detailed than the XTZs, which were a bit bright and harsh.
I eventually moved on to Martin Logan Vantages which are in a different league altogether!
