I came real close to buying a pair of SF Cremora auditor M's. What stopped me was hearing the Dynaudio C1's (which I bought for the same money). I have since upgraded to the C1 signatures. The SF sounded great BUT a little more laid back than I prefer.
That being said if you haven't heard the dyn's I would suggest listening to them.
