I own a pair of M30.2 40th anniversary. I have listened to some other speakers since I got them 4 years ago. Afraid to lose that outstanding midrange and soundstage that is so superb with vocals. This speaker is so easy to listen to with its neutral and accurate timber.
i recently did an AB comparison with the M30.2 XD and a pair of Fleetwood Deville. Nice but it not float my boat.
However the Devore 0/96 I listened to right after were fantastic. Wow! This was something else. Would not have the bass of the 40.3 but in terms of soundstage, texture and organic sound , the DeVore would be something to consider IMHO. A lot more expensive than my M30.2 obviously, but in the price range of the 40.3
