recommend entry-level high-efficiency loudspeakers

I really like the Omegas, especially the Grande 6. If you can do some assembling, Madisound's BK-16 kit is pretty good, their recomended kit w/ super tweeter is about $600., I ordered just the cabinets(precut, just assemble and finish) and a pr of FE166Es for under $400. I also have Cain & Cain Abbeys $1500. new., same driver. Common Sense Audio has an assortment of single driver, high eff models using Fostex, Lowther, and their own new Audio Nirvana drivers, havn't heard them, but they look nicely built, available assembled or kit. All the above spkrs models use Fostex 6" drivers (166 or 167), some people prefer the 8"(206,207), i like the balance of the 6. One thing to remember about the Fostex drivers is the looooong break in time, after 100 hrs they are listenable, but really need 1000+ hrs to smooth out!, i think a lot of people are turned off by the Fostexs because they really havn't heard them at their full potential. The imaging and coherency of single driver systems is addicting and it's hard to go back once you hear them properly set up and run in, no they are not perfect. I use mine with a sub and they still have that slight midrange peakyness, but i'm convinced i can tune that out with minor tweeks/adjustments. IMO they do so much right, i can't think of anything else in your price range that compares with SETs or Tripath chip amps. Here's another idea, buy a Sonic Impact T amp for $30. and spend a lot more on the speakers to start out with, then try some of the great SET amps out there as your budget permits. Just one mans opinion. Good luck, have fun and enjoy. Alan
