Seems like the BK9 just cam out and now it's mute in conversation lately,......for that matter so is everything else compared to T5.....I have asked my self what can the T5 possibly do that I can't do on my S950 or any of the other great arrangers on the market already, like BK9, Pa3x, Pa900, Audya, etc, ?.....if it's not "miles ahead" of the T4 I'm not interested....but if it's Lighter, Smaller, then previous, and has some Professional Features that are really impressive I could see myself looking more into it, otherwise same old ..
