Who hear the Hyperion at the CEs this year ?

I heard it.

Dlwask, you brought up a good point. The electronics could be the cause. Who knows?

Fatparrot, it's Hyperion Audio HPS-938.
Honest1, I also felt the same. From the buzz on AgoN, I was expecting to wowed! However, there appeared to be an uneveness (imbalance) in the frequency response. The trebble seemed accentuated (a little bit honky & horn-y :-)). There was also a bit of suck-out in the midrange.
To be fair, the HPS-938 were fast and dynamic. Perhaps, the demo pair was not broken-in. I would like to listen to them again, but a broken-in pair.
