Ok then......I seem to see a pattern emerging here:
The MS2s are great phones along the upgrade ladder that just can't compete after a major upgrade. That's Cool; That's understandable.
They are also a bit cooler and analytical than some would like. And that's cool too since lots of audio studies over the years have suggested, in speakers anyway, that a warmer sound is prefered by a small majority of the total population of listeners.
So, there is nothing WRONG with MS2, they're just not everybodys cup-o-tea!
But yeah; they are heavy! My 11/16" 12 point sockets have told me that!!
For rock(and I've bought Nothing BUT Rock since getting my MS-1s in March!!)my MS-1s shine! I'm sure that for rock the MS2s would be a great choice. Unfortunately over half my collection is classical and/or "acoustical/other" stuff that I tend to find a bit less enjoyable with the MS-1s cooler presentation. Still good! But not quite.
So, perhaps going with my other option in the "Battle of the Twos" IS the better way to go in my particular situation.
I'll get the warmer sound that well over half my collection prefers, I'll get the lighter weight that my ears prefer, and I'll even find myself somewhat immune to the most horrible effects of the Upgraditus Bug!
Yup; sounds like a plan.
So: Thanks for the inputs guys; as always: most helpfull indeed!!
