The Duos will reveal any shortcomings upstream. If you have a zippy SS amp or pre, it will be laid bare.
Be sure that the speakers are properly set up (leveled, speaker wire from amp to mid horn, jumpers from mid to tweeter and sub, distance between speakers 83% of distance to your ear measured from top of tweeter cylinder, toed in so that rear outside frame knob just appears to touch inside of front outer frame piece when viewed from listening position), that you're sitting at least 12' away, proper sub polarity (higher level at xover frequency using a test tone - reverse the sub leads to test). I also find that using a low seat (or slouching so that my ear is just below tweeter axis) can tame highs on bright and/or grainy recordings.
The speakers are NOT bright when properly dialed in.
