Pass X150.5 or Odyssey Stratos monos?

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.

It was because of this, your Revels looked like a 2ohm load to the bridged Kahrtargo monos and probably were going unstable.

The Kismets range in price from 5500 in the top tier cases.
to lower in different cases.
its not the cases, it’s the guts and top tier parts, capacitors etc!

 Don’t want the best cases, get the top amps in smaller cases.

 Call Klaus and chat and hear him!
he will put you in the correct direction.

Pass allows a 2 week trial with a 5% restock fee and freight both ways.
Maybe out $600 if they are returned.
Do not know what Klaus offers.
My advise is to try the Odyssey first.

Thanks everybody. Please note that the Pass I reference is a dot FIVE not eight. I can’t afford an 8. The .5 can be bought used for roughly the same price as the Stratos Stereo Extreme or Stratos monos basic. I’m aware of the fact that Klaus does custom builds and there are multiple tiers/options. The Kismets are out of my price range so they are not a consideration.
