Welcome to the saloon. The 7100, like all the multichannel Outlaw amps is built by ATI for Outlaw and as such shares the same high quality construction as the others. I have the 7125 and the 7500 amps and both are powerful and quiet. The Adcom is rated at 125 watts all channels driven and is comparable to the 7125 in power. Although the 7500 is rated at 200 WPC, that only results in a 2 db increase in SPL but provides a lot of headroom for transients. Remember these are continuous power ratings vice peak power ratings... so the actual available headroom is quite substantial. Although Bryston makes a great amp I would not hesitate to buy the 7500 or 7700 instead because the cost is less than 30% of the Bryston and the performance is very comparable. I think the 7100 will be a great addition to the system especially since you now have 12 channels of amp. You can use two pairs of the Adcoms amps to bi-amp your mains if possible and still have plenty of power for the rest of the system. You may not need another amp.
