The short story is that Bob brought in some 2134's to do a side by side mod test with before we ever shipped the first modified speaker, to compare with the 1642. For 2 days now we've tested and confirmed with our ears (not spec sheets): in this speaker and mod application, the 2134 actually delivers a more full and natural response. Therefore, without having actually shipped a unit yet (we launched this mod in the middle of a backorder with Yamaha, and none of the mail in units have even arrived to start on) our Burr Brown will be the OPA2134 for every speaker mod done here.

voidar: if you get the chance to try both, I'd love to hear your take on it. The presentation of music playback is better served, and is the best fit for this. I'm very excited about this actually, it makes better even more...better (either of these opamps will blow away the ones Yamaha uses stock).
