Grunt, if you like the clarity of your M22's, the M60's might be a little setback for you. I would recommend taking the leap to the M80's. Just in case you were thinking of an upgrade...I did a review a while back :-).
My post was a bit confusing, I was just talking about upgrading in general not me specifically. I already have 3 M80s up front and recently bought 2 M22s to try as rears but decided on an additional pair of QS8s. I liked the M22s so much I didn’t return them and plan to eventually put them in another room when I get a house. For now they are on top of the M80s to use when I don’t want to use headphones but also don’t want to bass extension of the M80s annoying my apartment neighbors. Thanks for the thought though.
Cheers,
Dean
