I would have thought bi amping using different brands (unless gain matched) would cause all sorts of potential issues.

I have heard great sounds from mixed brand pre/power combinations but have never come accross a mix of power amps driving the same speakers.

Whilst I have convinced myself I have heard improvements with bi wiring I accept the reality may be very different.

As always "let your own ears be the judge".

2 557's would be my tuppence worth.
