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!
I don't see where any of the above responses mention sound quality.  Resale value, after sale support and some theoretical technical issue are relevant, but they should only be considered after sound quality.  I have not tried either amp with you particular setup so I really don't have an opinion.  I just wouldn't be so quick to dismiss the Odyssey.

I would not have dismissed so quickly, if it were just a stereo version and not bridged into mono, stereo amps.
But still would have given the Pass the nod.

Odyssey Kismet monos!

 Read reviews, Kismet monos!

 Standard a
Stratos, are great amps, but when you go to Kismet level, you will hear a huge difference.

pass amazing.... of course they are!

 Do read kismet reviews, and call and talk to Klaus!
he is honest, and will tell you truth.

no matter amp (s) you choose, you will be happy!
I actually owned a pair of Odyssey Audio Kahrtargo monoblocks and found they were horrible in my system. 
It could have had something to do with the output/ input impedance mismatch between my preamp and amps. Make sure ratio is at least 20 to 1 
I own Pass Labs now and will never look back
