Fusion - I have Lores in a 12 x 13' room and they do not overload. I also have a pair of Tekton Katz Meow (8" main driver)and they play great in here, too. I don't think you'll have any problems with the M-Lores being too big. FWIW - I've had Maggies, Logans, and KHorns in here. They were all too big, although I didn't realize it until I started playing smaller speakers.
I don't know about the M-Lore, but the Lore has a crossover. I thought it was just a cap before the tweeter until yesterday when I looked inside. A couple of coils, a few resistors and a few caps looks like a crossover to me. I don't know the crossover points.
I've had a 2A3 SET amp that I built in my rig for the past couple of years or so and loved it. The other day I got a Manley Stingray for just under your budget and like it a lot with the Lores. It's got the detail of the SET but with balls. I like it a lot better (for now, anyway). The Stingray uses Parallel Push Pull EL84s. I can recommend the Manley, but there are many choices for $1500.
