It's a tube preamp for the audio section, which almost sounds reasonable until you remember that it's a fucking bluray player. Anyone with a home hifi setup who actually wants a tube preamp will have an Outboard tube preamp connected to a real poweramp.
They won't be using the 7.1 surround sound built into a bluray player.
Cursed "audiophile" bullshit
@ajroach42 and they could have used nixies instead of an LCD, missed opportunity to sell audioheads more tubes
