Why are there no Reviews of the Pass Labs XP-22. Is there anyone with strong feelings?


I have dug into this as much as I can and see no real Reviews of the Pass Labs XP-22. The comments seem to be fairly vague and incrementally from the XP-20 it seems as if there is not big jump to the 22. 
Is there anyone with strong feelings about the pre?

Had the HPA-1 for almost a year then moved up the chain to the XP12 for 7 or 8 months then upgraded to the XP22 and couldn't be happier. Running the XP17 phono at the moment but would love to get the XP27 if funds permit. Amp is a X250.8 so the synergy is perfect between components. After living with the XP22 now for about 4 months there is no looking back or going back. Did the tube thing for 20 years, was even the North American distributor for Eastern Electric, now retired and Pass for me was the way to go. Tube tone without the hassle of tubes.
Morningstaraudio - I am in exactly the same place as you.  After 20+ years of tubes, this is the first time I have not had any tubes in my system and I don't miss a thing.  I did recently upgrade from 250.8 to 260.8 monos.  They are still breaking in, but a nice improvement over the already great 250.8.
Tricon_Dave, there are a few pieces I want at the moment so the 260.8 will have to wait but thanks for putting them on my radar.
 My digital components are top notch but I'm lusting over the Marantz SA10 for some reason. To many wish list dreams.
I was just wondering if anybody out there has tried the new Pass Labs XP 12 or XP 22 with class D amplification? Something like the Merrill Veritas/Thors or the Bel Canto 600M mono amps? Just curious as hell if this is something that could lead to synergy of any kind for us guys that don't already have a Pass Labs amp and are considering one of their newer pre amps in the near future.
