I may be the only one here that owns the Inbal/TMSO M2 (and also the M3, and the Czech PO M5). It's been a while since I listened to it, so I cannot provide any details. It didn't make the same impact on me as the M8 from these troops (as I've mentioned before, their M8 is far and away my favorite M8), but it was quite enjoyable. My HT/Music listening room has been under constant remodeling this summer, so I've had few opportunities to listen to music.
Of the three newest Inbal releases from Exton, I found the M5 to make the best first impression -- and I've only had a chance to listen to each of the M2, M3, and M5 once.
Sorry I cannot be of much help here.
