Several responses. 1. Bryston has been around many years and their amps are known for their rugged build quality, reliability and ability to deliver high current to current hungry speakers. Back in the day, some folks felt they did not sound as good in the highs and upper mids as some "others" that were much more expensive. They sounded great to me with good dynamics. 2. Regarding bridging: a bridged amp will see a 2 ohm load driving a "4 ohm"speaker. Remember a speaker is a reactive load and the real world impedance is all over the place when playing
music. Most bridged amps are rated at 8 ohms so this makes for potential problems. You miight ask: Is the amp in question 2 ohm stable? 3. I would not consider any speaker that takes 250 + watts+....and tons of current to play as loud as I want. Why would you consider a Maggie for ear injuring volumn levels? Playing loud is not it's forte! (Ha!) You can drive any number of horn loaded designs to 112 db or more with a good 100 watt amp. This is better than driving a power hungry speaker to its limits and the limits of the power amp. Hope you have a big space. 4. I had Maggie's for years and had no problem driving them with high current amps that delivered "100 watts" at 8 ohms and double that into a "nominal 4 ohm" speakers. One amp, an ARC D-52, played both Dalquests (pretty power hungry!) and Maggies to uncomfortably loud levels. 5. I have dynamic speakers in my main room now because of placement issues as well as available power. Good luck! ENJOY THE MUSIC!
