I just ordered a pair of these new Raidhos and I'm so excited to receive them. The woofer has been upgraded over the original X-1s which have garnered all sorts of praise from the audiophile press. I heard my first pair of Raidhos about three years ago at a retail store in San Francisco. They were the C-1.1s, and as soon as the music started, I knew I was hearing something special. The midrange and trebles were so sweet and detailed and the soundstage was immense. Recently, a friend of mine bought a pair of D-1s and I got to hear them on my system, and I knew from that point I had to get a pair with that fabulous ribbon tweeter. For those who may be interested, the XT-1s retail for $7,600 in Piano Gloss Black and its matching stands sell for around $800 depending on finish.
