I answered your other identical post without seeing this one, but why do you think the ADS speakers are "not modern"? I don't know about your L1090"s, never having owned that particular model, but I do have a pair of L1290/2's and L1590/2's, some of the best ADS' ever produced, and you will have to go a long way and spend a lot more money to equal their equivalent. "Newer" doesn't always equal "Better", IMHO.
