I would assume the next TOTL hifiman will have a bit better sensitivity than the HE-6, requiring 50W plus speaker amplification is a bit of an inconvenience to say the least, in my mind it comes across as a bit of a design flaw (just a personal thought.). So I guess I am sticking with my HE-500's as I prefer a transformer coupled tube amplifification.
Those who own the HE-6 who like SS should look at the VSSA on DIYA, it is a step up from the first watt amps and designed in the vein of a 70's amplifier with a modern lateral mosfet.
I am curious if Hifiman has dropped any hints of a replacement/upgrade to the HE-6 any time soon ?
I would love it if they launched a viable competitor to STAX,
