Pass X150.5 or Odyssey Stratos monos?


After months of research and mental anguish ;) I've narrowed down my search for new amplification to the two in the title. There are obvious differences like the fact that one is a stereo amp while the other are monoblocks. Anyway, if you had to, which option would you go with and why? Thanks!

 Monoblock owner can't take the truth, that the stereo is a better amp.
I own the latest version of the Kismet Stereo amp and all I can say from 'my personal' experience is that it is fabulous.  I have owned lots of of quality gear from quality manufactures over the years and my Kismet stereo amp is my favorite amplifier that I have had in my listening room. 

I have a friend who owns Pass Lab gear and it is great, love it.  It has some advantages such as astectics and resale.  I have not done a direct comparison in my listening room so I can't comment on which sounds best. I would suggest not to underestimate the Kismet. 

Just got a Pass Labs X-150.5 for under 2500 dollars.  I have Pass Labs X-250.5 driving Audio Physic Virgos.  The amp is fed by a heavily modded Air Tight Tube preamp fed by a Asi Teknology mid-level mod to a Cambridge 841 CD player.  The sound of this system is sublime - impactful, visceral, dimensional with a tremendous soundstage.  For my reference system I opted for the x-150.5 because 150 wpc should be more than enough for my Revel F208s and does not weigh 100 pounds like the x-250.5.
