I had a pair of ADS L1090s for nearly 10 years and tried several amplifiers with them. If you want larger ADS's to sing, you really need a high current SS amp, preferably with high power as well. An '80s Technics receiver? Naah. Jolida tube amp? For the mids and highs, maybe, but it'll short-change you at least a half octave in bass extension, let alone control. For an integrated, I'd look into the Anthem 225, something with power *and* current.
I had been using a Vector Research receiver with mine--it's fairly high current, for a receiver--60 wpc into 8 ohms, 90 into 4 ohms. Then I hooked up a VSP Labs Trans MOS Gold Edition power amp--50 lbs., 200 wpc, stable into 0 ohms, and the speakers came alive. Suddenly there was bass. The midrange and treble took on a liquid, more organic sound.
You may want to consider separates; I would look into Parasound, either the Classic Series or Halo, whichever fits your budget and equipment rack.
