Bryston sst2 series or Parasound Halo series?

You are a very lucky lady!! Thanks so much for the insight. I use the Monster HTS 3600 MK11 power conditioner. Not too bad, but it's funny that a buddy of mine suggested upgrading my power conditioner just yesterday. Furman was on the top of his list. I have the BDA-1 DAC by Bryston and I love it for sound and build quality. I also use the Arcam av9 as the preamp.The music is played by a Sonos music server and the BDA-1 is a great match. My system doubles for music and movies. So not as pure as your 2 channel system. But what can I say, like so many others, I want the best of both worlds. I'm only about 6 years into this hobby but having a heck of a lot of fun.

Better listen to a Halo A21 before deciding Its truly an outstanding amp!Do some research on it!Just to through this in the mix of power conditioning for amps that wont thin the sound at all, I installed a PS audio Soloist Premier inwall conditioner just for my A21 and its never sounded pinched strained congested or anything negative. It only brought out the best in fact dynamics where louder. Just for an ideaa of its abilities PS audio recommends placing one before all of its conditioners, even the Power plant premier. I use a Quintet on a seperate line for my frontend and tv.

pretty close. I have had the 7 sst and the JC-1's and it's a toss up. Haven't had the SSt2 in my system, to tell if there's a huge difference. But I loved both amps with my Maggies.

Byrston's have a really special match with Maggie. I love the sound of them with a tube preamp in the mix.

"Are you interested in the multichannel amps or mixing 2 channel and 3 channel?"
I am open to suggestions. I have even thought of using a 5 channel using 2 on the fronts hi and low each and the 5th would drive the center. I'm not familiar with ATI but they seem pretty versatile. I thought about using Halo A-21 in mono mode but I'm told they need an 8ohm load when in mono. My Revels run at 6.5.
