What speakers would be an upgrade from my klipsch la scallas and my Klipsch Chorus

I sold my vintage lascalas for vintage altec model 19s .Couldn’t be happier. The altecs go very low and are more dynamic and just as sensitive. Love these altecs. a nice pair is within your budget. 

Very familiar with the model 19s. The lack of coherence ( between the woofer and horn ) is something I cannot live with. As far as the B&Ws, never have I heard a pair that can reproduce the trumpet playing of Miles as accurately as my Lascalas ( as well as some other " good " horns ). To each his own, right. To the OP : I am aware that you are new to the Gon, and we welcome you, but I feel you are very confused, and not sure of what you want, so you should start listening to other things before you make a switch of any kind. We are all here to help you, given the fact, however, that each of us have our own priorities of what sounds best to each of us. Enjoy ! MrD.

Thanks mr D I just bought a pair of definitive Technology bp9080x there on the way as I wright this. I think to get the mist out of these klipsch speakers you have to run a tube amp and I’m not ready for that yet.

Good luck with your new speakers....  just know that you don't need to be afraid of tubes, especially if you have efficient speakers.   There are many good tube amps that are reliable and affordable.   Quicksilver and Rogue come to mind first , but there are plenty of others.   

Great tube amps aren't "euphonic" or muddy or anything other than musically accurate, more linear, and hipper...unless you have one of those new Pass amps, which in itself is pretty hip even with zero tubes. Otherwise I get that many don't feel like chasing after the lure of "better," older, more rare, less rare but great and you don't know it, expensive or not, finger burning, well regarded, pure crap, U.S.A. sourced, Chinese, Russian, beautifully glowing, exploding, gold pin, rusty pin, SS (although replacing a tube with a SS device seems like heresy), or otherwise always burning out eventually, tubes. I get it.
