Hi,

The T2 clearly still sounds very good especially in the right hands.

Yamaha has a distinct sound that is distinguishable in each model which attributes them sounding similar in some cases but the differences are most noticeable when the new sounds that are exclusive to the particular model are used.

For example, I've had a T4 for around 6 weeks now and I was hard pushed to tell the differences between the same sounds or styles that were on both keyboards but clear as day where they differed. It's probably the same with the T5 in some respects and will continue in this cycle.
