McIntosh XRT30, 29 & 28

Has anyone examined and listened to the current top-of-the-line McIntosh speaker system, the XRT30, and/or to the similar XRT29 and XRT28? (1) The XRT30 consists of two very tall (76") columns, each containing vertical arrays of 30 4-inch cone midrange drivers and 25 1-inch soft-dome tweeters; the bass drivers are in two separate enclosures, each containing two 12" woofers. (2) The XRT29 is simply the same columns as the XRT 30 system (containing the midrange drivers and tweeters), but with no woofers. (3) The XRT28 is a somewhat smaller system on the same general principle as the XRT30 but with a somewhat more modest driver complement: two 76" columns, each containing 20 4-inch cone midrange drivers and 16 1-inch soft-dome tweeters, but with the base of the column containing two 10" woofers (no separate woofer enclosures). I am very interested in these speakers and would like to hear impressions from anyone who owns or has listened to them. Thanks.
