Do you guys think an Icon iDo Amp would be enough to power the HE400s? It's probably the only way I'd be able to take advantage of an outboard DAC... Seems like a nice little unit, but I'm not sure how much power it puts out into 32 Ohms. Any engineers in the house? If it puts out 12 mW@300-Ohm what would it put out at 32 Ohm? The rest of the specs are at the link.
I think it's easy to drive HE-400 so this should be fine. But if u can wait few days till I get Magni and Modi which is same price as this unit I can let u know how does that work.
