I achieve excellent results with my XVX in this location. The last pic is my dealer's showroom. As you can see there is tremendous variation in the location of the XVX. However, I strongly suspect that JiminGa is correct concerning his statements regarding the best, if possible XVX location. Ideally, IMO, the XVX is designed for a SS amp exactly like the Gryphon and all that marvelous ancillary Gear. However, it's a testimony to the versatility of the speaker that it can sound really good in MF's room, my room, or my dealer's room. It's a very musical loudspeaker that wants to please its owner. That's the kind of speaker I want. However, I must say that I haven't heard the XVX at my dealers and I would wonder if a better location, moving them out in the room considerably wouldn't be better. As I have said, I absolutely love my sound. It's really amazing what my 3500's can do but they are no match for the Gryphons. However, my Thor and MC2.1KW located on an X-material plinth/ horizontal lie is something to behold. Note the 2K watts in the second to last pic. My bass is truly incredible both in quality and quantity. A Thor has 6 dB higher sensitivity and significantly more output than a Subsonic because of its 15" woofers. It was never designed for stereo but meant to replace the XS. I have it located exactly as Dave Wilson intended it to be, and my bass blend is perfect. My bass is bone crushing.
My estimate is that I have about 900K in my system and at least 150K in power. I'm obsessed with proper power. As a consequence I use nothing but Wel Signature and Dragon balanced IC's and speaker cables that cost a small fortune. And Dragon power cords and Niagara 5000 and 7000 conditioners with 4 dedicated 20 amp lines. Also a Transguard Tg60 between me and the light pole that has a superb filter. if your power is not right, forget it. I love the AQ solid silver. It improves my clarity and resolution an order of magnitude. I basically agree with JiminGA but the XVX can be made to sound superb in rooms of many different sizes and configurations, just not as good as the installation shown here. I wouldn't trade what I have for any other gear in my room but my room is the limiting factor. What you see here is the absolute ultimate. It's amazing that both Vitus and Gryphon are Danish. I can't see much difference in their gear both of which are Class A and of incredible build quality. They are the best, nothing else comes close, IMO. But of the two, are their distinguishable qualities? Does anyone know?. I'm sure your set up sounds good. You would need to experience a large room with plenty of space off the front wall and above the speakers to truly understand what these are capable of. Neither you or your dealer really know what is possible with these given the respective set ups and electronics. It won't change the basic sound of the the XVX but the scale and the realism will grow exponentially. As to subs you certainly can use one Thor as you do. Magico has done similar. However, if you are starting with a blank slate get 2 subsonics in stereo and spend a couple of months getting them right millimeter by millimeter. I'm not criticizing anything you've done. My room is not optimized either. I'm stuck with what Ive got unless I move. My friend actually built this room to optimize the XVX specifically. It took 2 years. I don't know about your wife but that's a no go with mine. You also don't have the width for 2 subsonics so your set up makes sense. My post was really about what is possible with a blank slate and what an enormous difference this makes for XVX or any other speaker really.
