Edgy, bright highs on Avantgarde Duos


Hello:

I'm finding the top range of the Duos to be very bright and fatiguing. I presume this can be tempered with a good matching amp and proper speaker cables. Has anyone found this to be the case and what components tamed it down.

Thank you for such informative advice. At this point, Art Audio Carissa, ASL Flora and Synergistic Research cabling. Set up seems more exacting with these speakers than with conventional designs.
Yeah, it's a system, not a set of speakers!
go tube gear throughout (as the subs are already using SS amps to drive the woofers).
Chris, why not try your Audio Aero monos on the Avantgarde? Do you happen to know how many hours of break in there are on the Duos?
