Hi Ian!
Well, the 3x will have to sound MUCH better than my PA800 to justify the extra cash, and the attached speaker is a MUST ... so if it isn't stellar - I am not a candidate. My setups are too streamlined to ever rely on a PA system or amp for my personal monitor - I need it in my face at all times, and at a good volume level and quality. The new TC processor interests me more than the kb upgrades ... we'll have to wait to see. I know you'll love that T4 - it's reeks Yamaha, as do you. ( in a GOOD way! )
Now, forget about these posts and go play that thang!!!!!!!
