You gotta take this on a case by case basis, considering both the amps and the load. Not just the minimum impedance but the reactance. For example, I've got bridged Plinius amps with 4 ohm Genesis ribbons but the ribbons are purely resistive so there is no problem. With the Spectrons and Revels, I would think monoblocks would be the better choice. The Spectrons were designed for this and benefit by going into differential operation.
Monoblocks vs Bi-amping
I am considering buying 2 Spectron Musician 3s to drive my Revel Ultima Salon2s. Which is do you recommend 1) monoblock configuration or 2) both amps set up in stereo, one driving mid-ranges/tweteters of both speakers & the other driving the woofers? I would think bi-amping would be superior since the each amp would see a more stable impedance profile.
