Bridge or not to bridge

You can't bridge any of the Acurus amps. Their design philosophy was way too minimalist to allow that sort of option.

as a rule, bridging significantly degardes damping factor.
Listening tests are in order to determine possible effects in your own rig.

I've questioned bridging myself. I have 2 Krell KAV-250a power amps bridged output 1000 watts per channel driving a pair of Martin Logan Monoliths bi-wired. Should I bi-amp the speakers feeding 250 watts to each of the 2 woofers and the 2 panels? I'd go from 2000 watts to 1000 watts total, but would I gain detail and control? What do you think? Henry

Personally, i would recommend against bridging and just shoot for a bigger amp if you really need that much muscle. Most of the reasons have been previously stated.

As to Trollmuse, if you can't do it with 1000 wpc, you're not going to do it with 2000 wpc. I would always take quality over quantity and you should have a very fair measure of both running it at 1000 wpc. Sean

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.
