Can anyone offer a short explainer on USB vs. optical input on Linux? I'm a newbie when it comes to this stuff and am looking to drive the Fostex headphones and possibly external speakers if it makes sense. The MD photographer paired this with those headphones, which I'm assuming seems like a not-quite-subtle signal that someone there thinks these pair well, so maybe this is a decent place to ask.
I've read about folks having driver-issues with USB on windows that were solved by using optical input. What I'm unsure of is if that happens on Linux/if it even works, and if optical out is reasonable on Linux, if, everything else is equal, I should prefer one or the other. If it matters, this machine runs Debian and the motherboard (Asus X99E-WS) has onboard SPDIF out.

You probably don't want this for your X00s since this amp has a less than optimal output impedance.

yeah, i dont think a tube amp would pair well with them either.

treyking, is that because of the typical sound signature of a tube amp, or because of the output impedance? I'm not sure if this one is OTL, but that would make a difference. Just curious about your opinion and as to why you feel a tube amp don't pair well with the Fostex'.

i have yet to buy a tube amp, but have been wanting one. problem is that i would be pairing it at work with my fostex th-x00 or denon d2000's, and i have repeatedly read that tube amps dont play well with 'darker' colored cans. impedance is definitely a concern considering the fostex are at 25 ohm, but from a signature standpoint i understand that the lower end could become muddled or a little too heavy. perhaps someone else out there could correct/support this statement? again, i dont own a tube amp, but i read a lot before buying because i am borderline OCD :)

Thanks. I'm looking at the same parameters as you. I've got the Fostex th-x00, and I've been considering going for a DIY tube amp, but am curious about whether it's worth it. I'll welcome any more thoughts on the subject by anyone with practical experience with the Fostex.

i just picked up the grace m9xx (i really need to block this site...) and it has been said it was the perfect fit for those cans (the grace dac/amp could be seen in pics on Will's (from massdrop) desk beside the th-x00's when he was working with fostex on their sound signature, so i believe they were used in the tuning). however, with dual opamps, usb input to bypass internal DAC's, 1/4" AND 1/8" inputs, tube warmth, and DAC/AMP capabilities, i really dont know how you could go wrong with this one. seriously, $80?? i may buy one for my grado's or just to have.

I have tried a couple tube amps on the Fostex TH-X00 and they never impress. Bass ends up slow and muffled. Even with a basic FiiO K1 the sound is vastly improved vs my Sonic Adventure Reality tube amp (which pairs great with my Sennheiser HD600s).
For me the TH-X00 really shine when paired with precise, flat, low impedance solid-state amps.

Bummer! But I'm not spending $500 on that grace dac/amp. I have the E10K but the 3.5mm adapter is horrible. Any recommendations for a good 1/4-inch dac/amp for the TH-X00?

The Massdrop O2/ODAC would probably be the best, cheapest option, whenever it drops again https://www.massdrop.com/buy/massdrop-o2-odac It's perfect for the TH-X00 and I think only $200. Up the price and $312 for a JDS Labs version of that setup or $350 for the JDS Labs The Element. All cheaper than the GraceDesign and worthy competitors (or better depending on the reviewer).
For what it's worth, JDS Labs is having a B-stock sale https://www.jdslabs.com/store#b-stock right now for even more savings.
Until then you can do what I do (and love as my office setup). The E10k + Grado 1/8 to 1/4 adapter cable which solves for the 1/8 jack issue http://amzn.to/29eTuht I rarely if ever unplug the Grado cable and just use it's 1/4 plug. Works perfectly.

best of luck.

@Nemeios @Maxeytheman no, that is not the Monoprice 12678. It is the Monoprice 10620 http://amzn.to/29nFBAS.
The 12678 isn't nearly large enough for most full-sized headphones especially when you consider the protective padding. 12678 = 8 x 7 x 4 inches 10620 = 10 x 9 x 7 inches
It's snug as it is (which is what you want): http://imgur.com/gallery/LQrwq/
It's awesome though! And the cheapest way to put together a seriously protective case similar to Audeze or MrSpeakers.

@justex07 Thanks. Don't want to hijack the thread but Monoprice is selling these for $20 on their site. Picked one up. Thanks for the information!
