Most of the opinions you'll get will be from those having listened to the Dahlquists almost 30 years ago, and playing with the equipment and cabling of that decade(obviously). Very doubtful that they can actually compare what they heard then with what's being heard now. The ideal would be to find a pair that has been mirror imaged, had the x-over upgraded and piezo(YUCH) tweeter replaced with a ribbon to audition(I used to mod them when I owned my shop in Winter Park, Fl). You might try finding some contacts, local to you, here: (http://tech.groups.yahoo.com/group/Dahlquist/message/338?l=1) Done right, the DQ-10 actually sounds a lot like music, and that's what it's all about. YES- They require some power to achieve realistic SPLs, and an actively bi-amped sub helps too.
