Is dac variable output worse than fixed?

Got new headphones that need more power than my current setup. Was told to get a higher end schiit. The only issue is the l/r output from my dac is variable, and someone suggested that would be bad. The dac cost like 250 so i dont want to trash it if it's not going to actually negatively affect the audio. Could someone illuminate me on whether or not that will be the case if i run an ipod through a certified dac to a schiit via the l/r?

Thanks.

I'm not up on this stuff but from what I can see the Ido is a headphone amp 2v out with built in dac, if it's output is to low for the 38ohm 89db he500's, the get a $99 Schiit Magni 2 much more powerfull it's output impedance is .2ohm, Gain: 1.5 (3db) or 6 (15.6db), selectable via rear switch. And will give 1.2watts into the He500's 32ohm load. Leave the Ido up full.

Thanks so much! Glad to hear that variable output won't be a death sentence. Will do.

Last question. Since you recommended it, what would I set the back settings to on the magni 2 for the he500? There are 2 switches and im assuming the I and O are off and on, but do I choose high or lo?

Which ever one gives you the most usable range of volume with, min to max.
