Hey all,
Quick update. Been using the headphones for a week now, and I gotta say they're a huge improvement over my old Sennheiser HD580s. Even to an untrained ear, the difference was really audible--much more dynamic range, wider, more defined soundstage, and somehow simultaneously warmer and crisper.
I also impulsively picked up a FiiO E09/E17 Combo--which I'm returning. Apparently, most of these DAC/AMP units, whether separates or combo, power the line out at the same time as the headphone jack--with no mute button or switch. I have powered subs (Rokit 6) with independent volume on read, meaning it's not for regular volume control. As it turns out, there is no way to listen to headphones without the speakers being on. I'm surprised this situation doesn't come up mor often...?
I've discovered that NuForce has automatic switches on their headphone jacks that disable the line out when the headphones are plugged in. I also found that Audinst makes a unit with a what appears to be a switch to control the signal out.
Would love some feedback on my situation: any particular solutions to this problem I haven't considered? Any units in particular I should consider that would be good solutions for using my new X1s with my iMac--bearing in mind my speaker situation? As far as NuForce goes, where in the line should I look to settle. I could spend as little as $200-250 or as much as $1000 in their line of products--and other than varying inputs, I'm not clear on how to evaluate the added benefits amp/dac-wise. Also, they have this new UDA-100 coming out that looks like a good option, given that realistically USB will be fine for my purposes as a Desktop amp, but still not really sure how it differs from the lower models.
Thoughts comments suggestions?
