I like to run dynamics (hd650 and hd800) as well as efficient planars (ETHER Flow and Aeon Flow). I'm wondering which configuration would serve best, 4 or 8 ohm. I don't, at this time, plan to use speakers as this is a dedicated headphone amp.
Are there any real differences between the two choices aside from more gain? Would 8 ohms offer a quieter background, provided that it provided adequate gain?
kindly...
Matt
