Yes and no:If it gets loud enough, you should be good. From what I can gather it seems like the balanced output van deliver quite a bit more power regardless of input voltage (though I only took a cursory glace at the data...), so if you can find a reasonably priced cable to go with the balanced output it might be worth considering. It's something I'm considering for a mobile DAC+AMP and my rather insensitive Aeon 2 Noires, but desktop and a 660S should be much less tricky.

TOPPING A50s Headphone Amplifier
Although a dead ringer for its predecessor, the TOPPING A50s is a headphone amp with specs that outshine the A50 in nearly every way. Don’t Look Down With a THD+N of 0.00007% and SNR of 143dB, the TOPPING A50s’ noise floor is so far down you might get dizzy. Compare this to the original A50...

If that's what you meant than it's a yes.
Anyway it's more than enough juice to those low impedance and good sensitivity headphones like these three I do possess. I don't even use the gain +6db (except for maybe the K712 Pro).
Don't know about the HD 660s but I think I'm still covered (like you said).
