After some conversations over the summer, Opimax and I agreed to get together and listen to each other's respective systems, get a chance to hear other vintage gear. I'd been wanting to hear a set of 250TIs ..., he wanted to hear a pair of the pro monitors, but as luck would have it, he invited Emma and I to drop by today. He's got quite a system, with multiple speakers, a B-460 and Velodyne to carry the bottom end, and a gorgeous pair of 250tis that have been redone with revised drivers and CC networks. He's even had the supertweeters aquaplased. And what a sound! Very very nice.
With complex music, I think the 250TIs have a bit more resolving power - how you say it, better definition for each of the instruments in the music than our 4341s have. But he's more of a hard rock and blues guy, while Emma and I are all over the map.
That said - I think I prefer listening to jazz with horns on the 4341s - Miles, Ornette, Chet Baker - all of that, and at somewhat lower listening levels
But between the plasma and the power recliners, those glorious speakers and amps - what a fine place to enjoy music!
