Headphone Amp Power Recommended?

[LeShog]

So I am quite confused as I own a pair of Audeze LCD-2C with 70 ohms and 101 db/mw sensitivity. According to the headphone power calculator on headphonesty.com at grossly 80 mw they already reach a dangerously loud 120 db. Then why on Audeze's site it is written that they need a source with at least 100 mw power to properly function? They even recommend something that can give a scary 250 mw or more. Is there something more about power other than volume?

Here's tech specs of Audeze LCD-2C from manufacturer's site https://www.audeze.com/products/lcd-2-classic

Thank you

There is not.

Audiophiles just like their overkill Amps and are convinced they sound better (confirmation bias).

Are they loud enough for 'ya (without pushing the amplifier into audible distortion)?

When they give you sensitivity in mW rather than Volts or mV, picking an amplifier can be a little tricky because amplifiers are voltage sources and (mostly) "voltage limited". You get more wattage with lower impedance.

Thank you all I suspected that, but wasn’t 100% sure until now
