It seems like a different enough flavor from the Elites, and something I'd be curious to try since i've never heard a ribbon or ES headphone. The local Stax dealer doesn't allow auditions.
I always preferred Elites over Susvara and LCD-5, but I've only heard them on Dave + Oor, not Rossini + HM1, so who knows. I plan on re-auditioning all of them, but nowhere to audition ZMF,DCA, T+A stuff sadly.
Since I actually need a closed back, Stealth would be the front runner if the HM1 could actually liven it enough for me. Reviews are just too polarizing to be able to get an accurate impression of what it would sound like, but it's not promising. It seems dead(end) inside, which is not my cup of tea. I lean towards more dynamic sounding headphones.
Open to any suggestions
