I own both the 2ce sig and 3A sig. A lot of people want to focus on the room on deciding between these two. I would focus on your electronics. The 3A sig will reward the best electronics you can use. Top end stuff on the 2ce sigs will sound nice but really won't reach their full potential. I know this from my own experience. I was using a preamp/amp combo that cost almost three times what the 2ce sigs cost and was very pleased until I went to the 3A sigs and found out what I was missing. The 2ce sig are now in another system with a very nice integrated (but not in the same league as my preamp/amp combo) and they sound about the same as they did with the better electronics. I prefer the 2ce sigs with that integrated over the 3A sigs - the 3A sigs are just too revealing and demanding for that level of electronics. I don't know what the rest of your system is but I would take an objective look at your electronics before purchasing the 3A sigs.
