I’m confused. I went to a pretty big and renowned store. I was told that EF600 is not enough for HE6se or Susvara. Way not enough. But that’s what I’m using at home! It’s working fine with the knob at 9 o’clock for decent volume. I didn’t believe this info at all. Am I mistaken or was he just saying nonsense to sell more expensive gears? What’s your thoughts?
If someone talks in watts, they don’t know what they’re about. The measure that matters is watts into 50 ohms load. This will be completely different (around 1/10th) of what an amp cam output into an 8 ohm load, which is typical for a speaker.
Hifiman list 2W into 50ohms on the HE6se.
But that’s not the full story. The amplifier wattage spec is just where distortion gets high, not the maximum output. Many amps can sound amazingly good operating above that spec. I have used amps rated at 1W into 50ohms that have sounded amazingly good on HE6se.
Ah in that case EF600 should be enough with 5.12W per channel @32ohm balanced. Also the advertised 2W requirement maybe too loud for normal listening so perhaps just 1W would suffice. Everyone listens at different volume after all.
