I now have a handful more BKPs, as my signature notes, and I still agree with your sentiment. All BKPs do it more than most of the commonly used alternatives, but the RY still sticks out. I recon it is the combination of the clear and present high end, combined with the super fast and punchy low end, finished off with the output, which gets you there, but only goes as far as it needs to get metal. That open restraint in compression and output together with the rest gives it thas feel you talk about.
It punishes you when you screw up, but when you hit the notes right...oh my, it is something else. No other BKP has that like the RY does. The next closest things are the P90s. So maybe look at them for the next round Wayne_S, good chance youŽd love them the way you say you play.
