Why not put the Cab block at the end?

IIRC the only slight differences I heard were in the high frequencies with modulation effects (chorus, etc.); there was a bit more clarity/detail in the highs with the CAB block at the end. In practice, either CAB position works the same.

I always run the cab block at the end of the chain because I split my signal between my real cabs and Front of House. Best of both worlds.

That was another reason I decided to put the CAB block at the end; makes things easy when I connect 4x12's to the rig.

Given that most post effects are linear or "wide sense stationary" the order of effects after the amp doesn't matter. Reverb -> Cab is theoretically equivalent to Cab -> Reverb because linear systems are commutative (i.e. a * b = b * a).

I wonder if using the time/modulation FX all in parallel would show some small differences.....? That's how I've always run them...

Would having, say a reverb, delay, and a chorus, all in parallel, process and mix back together slightly differently (in particular, the highs) depending on:

-if a cab block was aggressively filtering out high frequencies first, limiting the frequencies the blocks can process, then mixed back together

vs

-having a full range of frequencies to process, then with the cab block filtering after they're all mixed back together?
