Bi - Amping

lordrootman OP

Halo A21+ on the mids and highs, because it’s "high bias Class A/AB operation" John Curl design, which will be better for the mids and highs.
And probably the Anthem ( Sixteen bipolar output devices per channel ) on the bass for the current in can deliver into 2ohms

And the Rotel Michi having 100ohm output impedance will have no trouble driving any combinations of amps you have

To me if you have the amps, it’s well worth doing as it will cost next to nothing to do and you’ll gain from it.

Cheers George.

Ensure that the gain on the different amplifiers are the same.

They won't be, and that's what the $49 Schiit Sys passive is for.

Sounds like a valid experiment. 
I might try this instead for level adj.:

Then you can hear from your listening position if it is worth pursuing.
Try it with cheap cables first.
Let us know how it works out.
