How much power is optimal for Hifiman HE-400i? I keep hearing that 2W per channel is needed, but Amir brags on HE-400i bass in his review of the JDS Labs Atom amp, which has 1W per channel. I am wondering if the Schiit Heresy might sound better with HE400i because of the 2.4W of power per channel. If 2W is not needed, where did this idea come from and why is it so popular?
Also, is it recommended to use high gain with planars? I keep hearing not to use high gain unless you absolutely have to due to increased noise/distortion, but is low gain actually taking full advantage of the 1W of power???
