For what it’s worth, I had a similar reaction the first time I listened to my M60s. My previous speakers were a pair of jbl’s bookshelves that I’d had for 15 years and got very used to their sound. The M60s sounded ‘different’, particularly I was having trouble getting used to the mid-high frequencies region the M60 produced. It was no coincidence, the jbls are famous for muddy mids and overly bright highs, on the other hand, the M60 are famous for their detail mids. For me it was just a matter of training my ears to what good balanced speakers should sound. Not sure how long it took, but it was worth it.
I fell in love with the M60 low freq. response and ‘stage’ immediately though.
