Pass X150.5 or Odyssey Stratos monos?

You need to educate more, https://ibb.co/x5CGWHQ

Better still find "just one amp designer" that doesn't bridge amplifiers to sell. To back bridging to have the same quality measured specs as the same amp non-bridged, into todays high end quite hard to drive speakers. 

Gotta wonder: how does the Odyssey Stratus Mono SOUND on a test bench?         It's been my experience: dummy load resistors have a very limited frequency response.      

Do you think that’s all it is, driving a dummy load resistor? you have a lot to learn.

And a non bridged amp will drive a 2-4ohm load better than the same amp bridged if you’d like to know.

Don’t you guys think a designer like Nelson Pass would have just bridged amps like his stereo X250 to make his mono X600????? or his XA30 stero to make his XA100 monos???

The kismet mono amps will drive 2 ohm speakers all day.....

same with the McCormack dna-750 amps.
they are no good, and their specs are tripe because they are bridged.

First ever I heard the McCormack dna750 amps called no good.
wow, maybe it’s you that needs to learn a bit.

call Steve McCormack, tell him the dna 750 amps which are bridged dna 500 amps are no good.
really, he loves to speak audio.

Or call roger sanders about his Magtech monos, which are bridged magtech stereo amps...

the Sanders amps are stable below 1 ohm, with the specs to back up!
   Old school maybe needs to go to school a wee bit to learn about modern electronics

"Do you think that’s all it is, driving a dummy load resistor? you have a lot to learn."         No, but I do believe how any particular amp SOUNDS, is vastly more important than how it measures.      But then, that's just my personal opinion.
