100w tube vs ss for Mag 3.6s

If your dealer will let you try the Cary out at home do it. That will tell the tale. I don't know the two amps directly but have always liked Maggies with tube amps. I also am confident that the ARC is a good sounding amp based on the findings of a friend whom I trust in such matters. There is always the possibility of bi amping using poweder subs. There are many advantages to this sort of set up and allows you to mate a smaller amp than you could otherwise. I hope you are close enough to the dealer to be able to try it before you buy it.

I will say no to Cary audio tube amp. However, try to post this question or do a search at http://www.audioasylum.com/forums/mug/bbs.html

This is THE site for Mag fans.

I use 120wpc OTLs in a room abut half your size and it's JUST enough, high 90's. I also have sub-woofers but I run the 3.6s full-range. If 100wpc tube power isn't enough for you, I wonder if 200wpc solid state is going to go that much louder cleanly. Try it all before you buy, and that's my 2 cents worth.
