One R10 is #856, the other is #245.
I think I like the 245 more, its midrange seems even better than the other, something I didn't think was possible. It also seems to be a bit airier and soundstage is a bit larger. Bass impact is definitely less, a few quick A/B while playing Massive Attack's "Angel" made the difference very obvious.
Yes, the two cases are different. The locks are different, and the included instruction books are also different.
I'm using the RSA Raptor to drive the R10s, not the AT-HA5000. Believe me, I'm trying, I'm really trying...
Uh oh, Team Stax, I think Team Dynamic is going to very tough to beat.
