I decided to keep my XT-1s since the cost of the XT-2s was prohibitive ($18,000).
Let me just say again, the Raidho tweeter is exemplary, the best I've heard. There is a delicacy in the mids and trebles that draws one in emotionally. Never strident, even with questionable recordings, the tonal quality leans just slightly to the darker side of neutral. The soundstage is immense, both in the lateral and vertical planes—the speakers just spookily disappear into the soundstage.
The bass is respectable given the 4" woofer. Although rated at 80Hz as the bottom limit of extension, it sounds like it goes down another 15Hz. This makes the presentation of EDM quite enjoyable. Since the XT-1 is front ported, placement can be near walls without compromising the soundstage too much. After some experimentation, I have mine situated 20" from the rear wall. I can't comment on the differences between the ceramic woofer of the X-1s and the ceramic/titanium woofer of the XT-1s, but the purported difference is bass impact due to better controlled driver resonance.
Having owned multiple $20,000+ loudspeakers over the years, fit and finish is an important quality to me. I've never seen a better cabinet finish than the forest green Wilson Watt/Puppy 7s I owned. The XT-1s are available in gloss black and white, my pair being the former. On a scale where the Wilsons are a 10, I'd give the Raidhos a 9. There is no orange peel effect on the finish, just a deep, black reflection. Unfortunately, I can't say the same for the matching wood stands. Their gloss finish appears to be a notable step down, and the base for the stands have fine, swirling scratches on its surface. Additionally, there are no spikes, instead, inexpensive plastic discs that act as feet; I chose not to use them. The threading for the feet on the underside of the base is non-standard since it has a tiny circumference, so finding spikes that will fit will be a challenge.
I suppose the design follows the Raidho philosophy of using non-rigid stands for its speakers. At some point, I might try a different option since I've always adhered to the idea of using mass loaded stands.
A few last points ... the speaker terminals are flush with the backside of the cabinet, so banana plugs are a must. As is typical of new speakers, the hex nuts that attach the aluminum woofer and tweeter plates were loose when I unboxed the speakers. Careful tightening will improve the sound, and after a couple of weeks when the speakers settle into its environment, a re-tightening will be needed. Finally, as to be expected for this price point, the speakers are built as matched pairs with the serial numbers reflecting this.
All in all, I am extremely happy with my purchase. Music listening is a captivating, emotional experience with the Raidhos in my home.
