Aperion super tweeters and cables are burning in...impressively made with superb controls for crossover points and level/db for speaker matching. WBT binding posts as well👌🏻 On first listen, I am hearing just that slightest bit of extra sparkle on top that some of my previous speakers delivered, but with the organic fullness and tone that the Cornwall’s imbue. Potentially an important tweak to enhance certain recordings in a given environment. My Den is slightly subdued in supporting a completely open top end, so the super tweeters can compensate for what may be perceived as missing air in the upper registers. I’ll give them a solid week or two before final judgment is rendered.
