Tmcroy somehow I've become a bass freak realy believing that subharmonic bass freequencies drow the main line of a sound signature and imaging. I also have the same monos as you do and probably will be planning to acquire 200W/ch-ish SS amp that is probably specifically great for bass(I believe it could be McCormack DNA1). The speakers that I have are Totem Forest(a great value for the bass freaks). I will also look towards building an active crossover with Marchand parts since I also believe that there is no point using different amps in passive bi-amping.
It is OK to use amps of a same kind without active external crossover.
If you can wait and stretch you budget(not realy big) or even browse to find used models of Rogue 88(power amp) and Rogue Tempest(integrated) that are designed for biamping together, you'll never regret. I might mistake on model numbers which means there are Rogue amps ntegrated and power amp having the same output power and double outputs for bi-amplification i.e. do the research.
And finally, I've enjoyed reading such controversal responces although choose to stay with my position that is completely in sink with Tmcroy.
