So can anyone can affirm whether these are the same opamps as the E09K? 
 
I'm not sure why anyone wouldn't just buy this from monoprice. A little snooping around will find a coupon code that will reduce the price so you can buy strait from Monoprice and exclude the middle man. 
 
W/ coupon code 4MP12 it makes it about $90 or so shipped.

Same headphone amps(TPA 6120A2) and opamps (OPA2134), but the monoprice desktop amp... a FIIO E09k it is not.

Monoprice Desktop Amp
Opamp layout is similar but other than that... it's a diff beast.

I have zero need for the Monoprice DAC/Amplifier, but part of me wants to buy one to test it out.

I almost succumbed to gadgetitis last night, but was eventually able to talk myself down. I'd like to see some measurements on it though, since we know it's not just an E09K with a built in DAC in monoprice trimmings. If I used speakers at my desk, I might have gone ahead and took the plunge.

Does anyone have an idea of what the output impedance of it is? A reviewer on reddit would suggest that it drove his HE 400 fairly well, but Ill be driving a pair of philips x1's, which have an impedance of 30 ohms.  The price is attractive, but the only thing wrong with my mobo audio is the impedance mismatch; so it wouldnt make much sense to purchase this if the impedance was still mismatched by a considerable margin.
