LFF,
I have to agree with your assessment...as I got the same impression from the show.
Haven't heard STAX in a long time, they were amazing.
The Schiit stuff impressed me, as did the HE400. Scaling up in the Hifiman line didn't seem worth while after the HE400.
I enjoyed the Headroom setup though, maybe I caught them at a quiet moment in the hall.
And I was definitely not impressed with the overall music selection. Seems like many people try to impress you with their obscure music choices. It's obscure for a reason people.
