I had the same questions when it came to my pair of Jeff Rowland Model 1's (bi-amp or bridge). I posed the question to Jeff R., and in this situation, he recommended that bridging them would be much better. His reasoning being that the amps were designed from the ground up as mono (hence the 'bridged' switch on the back of the amps). I am currently running them in bridged mode (& bi-wired) to drive my Snell Type A/IIIi's. I did (per Jeff R.'s recommendations) have to bump up the internal fuses as the amps are seeing a 2 ohm load (Snell's are 4 ohm speakers). I guess it all depends on the amps. -John R.
