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

I recently traded La Scalla IIs for some B&W 804 D3s. Fantastic upgrade!  If I were you, I go with some Klipsch Forte IIIs. Then start saving for a Pass XA25. I think this is a match made in heaven.

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.
