i've owned the 1290 (good but very sensitive to pairing), the 710 (great tweeter) and the 780 (vg but not as good as the 710). the real gem was the L470, which i found for tenbucks at a yard sale--amazing clarity and surprisingly deep, tight bass for a little box.
Who uses ADS Speakers
I worked at ADS in The late 70s and Find they are one of the best home speakers ever.
I always loved their accuracy.
