$1500 will get you a used pair of Vandersteen 3As. Bass extension, and plenty of it, down to below 30HZ. A balanced, detailed, nuanced presentation that is emotionally involving and never fatiguing. And they are so open sounding, never boxy. Not as "exciting" as some speakers, but that's because Richard Vanderateen makes his speakers to reproduce the music, not add to it. Not the most beautiful speaker, but you're paying for components, not a beautiful enclosure. I have gotten so I like the way mine look. Plus they have a grand, large soundstage and great imaging. Another advantage is that they sound good on most any kind of music. I play punk, hard rock, classical, ambient, pop, jazz, just about everything and they good on all of it. And they are pretty good on home theatre also. No subwoofer needed.
I've listened to/auditioned a lot of speakers, including Pro Ac, B&W, Martin Logan, Genesis, Alon, Thiel, Merlin, Magnepan, Quad, Wilson, and many more, and am convinced that, for the money, Vandersteen is clearly the best speaker you can buy. Period. Until I hear something better anyway. BTW, I'm afraid the Pioneer will have to go.
Good Luck, Martin.
