I also had 2.2s and had listened to 3.6s quite a few times. There are some good deals on used 3.6s...some as low as $1,700 a pair and that is a steal for such a good speaker. They need a lot of power...preferably solid state power. The speakers are very demanding. Someone mentioned the 2.3s, but since you can get 3.6s cheaper used, no need to look at the 2.3s. Another speaker you might want to listen to is the Dunlavy SC III, they are going for somewhere around $3,000 a pair new, retail is $4,000. Much more easy to drive and not so finicky about equipment further up in the chain. I'm using these speakers with ARC electronics and I love them, haven't missed my 2.2s at all.
