I've had the m22s for awhile now. I was initially blown away by them. After a couple of months I began to have second thoughts. But, I hung in there and I can now say that I cannot envision myself parting with them. If you are used to an inefficient, laid back speaker it may take awhile to acclamate to them. But, it is indeed worth it. One thing I've always said about these is that I can't believe how all that sound can be coming from those 2 little wedge shaped boxes.
