Bi amping with two different pairs of monoblocks

@yogiboy Check again this will not work

@hk_fan OP has an OPPO the Pass is $17k

^^^^^THIS^^^^^

Unless the power amps are identical volume control will be a problem.

You will get a much bigger bang for your buck by upgrading your OPPO to a modern streamer/hard disk player and use your OPPO to rip DSD files.

Don't even think about bi-wiring, it's nonsense.

The whole proposition is ridiculous. Does anyone really expect two $5k speaker cables to sound better than one $10k one?

The amp powering the tweeter needs to deliver a miniscule load, it's not worth it.

I researched this subject extensively and unless you have exhausted every other option to squeeze out the last drop of resolution, forget it.

 Every case is different.  I don’t agree that it’s a ridiculous proposition.  It depends on several variables. 

I said it was a ridiculous proposition in the context that the OP would be better served buying a decent front end and some high quality speaker jumpers, they really make a difference.
