Mrtennis wrote that the Duets enhance resolution by placing a bit more emphasis on the treble. This is what I heard from the Quintet too - and it drove me crazy. I thought it over-emphasized treble - making it somewhat etched sounding - while also de-emphasizing the midrange. I think some might consider it an improvement as it gives the impression of greater resolution. It did not last more than a few minutes in my main system because I thought it screwed the treble up too badly. I connected it to my home theater system to see if it would be more to my liking there and attempted to watch TV. Boy was that a painful experience. Voices sounded very grating. I got halfway through watching a football game before ripping it out.
I think it would be better to go with something that does less harm. Like maybe a Cryoparts or B-P-T power strip.
