I've never heard the M60's but my room is 22x28 and I sit about 10-12 ft away and the M22's with a great sub and the vp150, and qs8's are plenty fine and he'd be happy. The M22's don't have much bass without a sub.
Currently I'm debating on a set of M60's or M80's so I can get the room towards the back to 85+db.
If you have a large room like myself you'd be in the same situation, otherwise if your in a small room the M22's with sub will sound just fine, unless your looking for it to be loud.
Here's the thread from when I was looking to buy.
