It's fairly powerful though, I cannot go past 25/31 comfortably and I am used to amping and using pretty high volume levels. Most of all my IEM's feel very well supported.
I'm not sure if this is for everyone but the site layout has gone very strange here at the moment.
What would the ipod be rated at then per channel. I think that would satisfy the above question in that event.
