If I used the GEC A2293 I would need four or eight tubes in my amp and I already have the GEC 6AS7G tubes so I didn’t feel the need to try them.That's a good tip, thanks. The A2293 data sheet states "low impedance" so I wonder if their use in Feliks Elise or Euforia would be a win for running lower impedance headphones, a potential Achilles heel of Elise / Euphoria due to their generally high output impedance. @mordy , any thoughts?
Except for my Sennheiser HD201 headphones (24 ohm) i don’t have any low impedance headphones so can’t be of much help.
I do have the Cetron 6336B 5A tubes that are supposed to be good for low impedance headphones but the Elise/Euforia can’t use them unless you use external power.
