What do you guys think, a single A21 or two A23's being used in mono bridged mode to power a pair of Bowers & Wilkins 804 D2s?

From Stereophile:

The plot of the 804 Diamond's impedance magnitude and phase against frequency is shown in fig.1. The speaker is a moderately difficult load for the partnering amplifier to drive. Not only does its impedance reach a minimum value of 3 ohms at 108Hz, there is a combination of 4.5 ohms and a 53° capacitive phase angle at 72Hz, and the

Parasound recommends 8 ohm loads for bridging. The A21 or bi-amped A23 are the choices. Bridged is not an option for these speakers.

Need a little advice

I have 2 Parasound A23's. I would like to use them to power my Monitor Audio Silver 8's. However, as these speakers are rated at 4 ohms, Parasound says I can't use the A23 's in mono.

I'm wondering the best way to get max power to my Speakers. Does the fact I'm also running an SVS PB12-Plus with the Silver 8's change the mono option now ?

Can I just run RCA's from the Recevier, LH into one A23 and the RH into the other ?

Appreciate any and all advice

Try bi-amping a single speaker. I use stacking banana connectors to make the switch easy. I recommend running 1 speaker only and, if possible, single blind test. At the very least, bi-amping will keep the upper-end clean if you run out of power on the low end.
