The T5 has lost most of the previous Yamaha CD like (Smooth) sound, and replaced it with a more live band feel, and this may be the reason you think it sounds bright and harsh. (Live bands don’t have round edges)
Hope this helps

Well put bill if you have played the T5 live and not just listened You tube demos, I played one of about 30 mins and I would buy one, I will certainly guarantee one thing, they will probably sell more T5 than T4 that's the way it is, Yamaha are doing something right and you can't deny that, and they will sell more T5 than all the other manufactures put together. They make what people want, simple.
