Gene usually knows what he's talking about, so I'll leave it to someone who's actually seen the guts of an M60 to refute his statement.
One thing is, in the photo of the three speakers tested, the M60 has black dust caps, and holes for the speaker grill. Those are features of the v2. The v3 has white dust caps, and magnetic speaker grill (no holes).
Other than that little statement about the break up at high volume, the M60s reviewed very well. No speaker is perfect.
Here's a link to the review:
