what's the word on the schiit magi? What would match up better with the AKG k712 the FIo e12 or the schit? Open to any input, but I don't want to spend too much more than $130 on the amp if I don't need to. Also this will pretty much be stationary. Thanks
I haven't tried the Schiit, but I do use my E12 with my K712 (more often than I did my Q701, actually). I have read a lot of reviews and impressions on both however, and this is how I'd sum it up.
They both are very good amps, and drive the AKG K712 pro well. They both have a fair bit of power, and output impedance so low on them, so those two things mean really sensitive headphones or those needing more power are both covered and the amps could be used with almost any headphone.
The E12 is smooth and drives the K712 very well with great refinement and no distortion. It has a couple fun switches to turn on a bass boost and/or a crossfeed to blend the L/R channels a bit for more relaxed listening (and less brain reaction, sometimes songs pan hard left or right and it can be jarring, this lessens that). Also, yeah you will be using it mostly stationary, but the E12 is portable so you have the option to use it in different rooms (bedroom, TV in the living room, take it to work) easily without having a hassle to unhook and set it up.
The Schiit Magni is an attractive silver desktop amp. Good price. Since it's a wall-plug-in desktop amp, you don't have to worry about charging your battery (though you can only set it up where you have a nearby free power outlet, and you have to be careful of noise from the grid mains). Sound-wise, reviews mention a clear revealing sound, which may balance the K712's slightly more warm signature. It's also simply an amp... sometimes it's attractive to have a simple device that does one thing. There's only one control - an analogue volume knob, and people like turning a nice volume knob on a desktop amp (the E12 also has a volume knob, but it also serves as a power switch and it's pretty stiff to turn unless you turn it just-so).
Which would I choose? I don't really know. I honestly AM someone who likes the simplicity of a desktop amp, but I feel that if I had a Magni I'd also want a portable amp because they're just very convenient. As it happens, I DO have a desktop amp, and I use my E12 whenever I need it's convenience. I'd probably be ok pairing down to an E11 plus my tube amp, but the E12 is basically no compromise in sound quality.
