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 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.

I bought 2 Stereo Stratos used this year.  They sound really really good, and being an audio tech, I "mono' ized" the 2 Stereo amps nothing else modified, just converted to mono by Klaus instructions.  All i can say is that you (Georgehifi) are wrong about the monos being crap.  The sound from the monos is up to another level! The sound is richer (tube-like), the soundstage is really better too.  
And if that wasn't the case, I could re-convert them into stereos right? 
So, please @georgehifi stop BS about Odyssey if you even didn't listen or test those amps.

@odysseyaudio Thanks Klaus for all your implication in your products! They really give us the highest price/performance for our hard earned money!!

I presently own Lorelei, Tempest pre, Stratos monos.  Very happy!!😊👌
