The T-series speakers are very good sounding. I have a pair of NS-70T's (3 way) and really like them a lot. They compare favorably to my other Yamaha speakers. The bass goes a bit deeper than my NS-670's but the cabinet (70T) is bigger and it is probably tuned a bit differently. The 70T seems like a "consumer" version of the NS-200m, they are very similar.
