Will I hear much of a difference between the HD598 and the HD600/650 if I only listen at low (to moderate) volumes?
 
Is it worth spending the extra $$$ for the HD600/650?

Do you own a decent (powerful) enough headphone amplifier to even drive the 300-Ohm HD600/HD650 headphones?

I have a Fiio Q1. I know that it's not the ideal tool for the job, but others in the forums have confirmed that the Q1 can indeed do a decent job of driving the HD600/650. (Remember, I listen at relatively low/moderate volumes).

I listen primarily via my iPhone.

Easier for the FiiO Q1 to drive.
