I heard a Transfiguration Temper I remounted on a SME Model 20 in a couple systems when I worked at a repair shop. Loved it, but didn't get more than a few minutes audition. I have a standing offer on the whole system it's in and hope to get it someday (and the Dunlavy SC-VIs it eventually sings through).
The Lyra is, in a word....clean. It's clean, dynamic, extended, and leaves no stone unturned. I would be happy to link you to a dropbox folder containing 4 24/88.2 wav files I made with my Kleos on a SP-10mk2/SME 312/SPL Phonos feeding a Lynx Hilo, if you'd like to take a listen! The first time I heard a Lyra, a Delos, the cheapest model, I was immediately sure I had to own one....it was just that good. My Kleos was retipped with a 2.5/75 Ogura by Joseph Long, the stock diamond is a 3/75, which is a Lyra exclusive. Perhaps you may also consider sending your Transfigurations to Mr. Long.
