About this deal

Ignore the Exasound E32 in yellow for a second. The red is FX-Audio DAC-X6 which has highest level of crosstalk in red. I have a DAC X7 (the model just after the X6) at home and measured it. There's a +30° phase shift between 1 kHz and 10 kHz. Is there something wrong with the thd+n x level graph? Shouldn't the curve rise with decreasing levels due to increased % noise? It is one thing pulling parts but the logistics involved in sorting salvaged parts from a myriad assortment of PCBs for reliable bulk supply of specific items for production are surely too costly and such parts would be out of dimensional spec. and not clean enough for automated placement. Could you test the output with the gain jumpers ( https://www.reddit.com/r/headphones/comments/5rk667/fxaudio_dac_x6_gain_jumpers/) set to "high"?

There also a Dilvpoetry one like the original. There are some difference. Dilvpoetry also made this revamped version.

Now I realise that this must be, for sure, transformer hum, as both these amps have theirs onboard (two, in the case of the H10). But, the X6's is external. The X6 comes with an OPA2134 opamp. I liked it so very much, that I felt silly switching in the LME49860 that arrived today by China Mail. I think I paid 2.30USD for it. (Keeping it real here, no snake oil extravaganza at these prices.) I felt silly, because the sonic balance of the OPA2134 (in combination with my modded T50RP) was so on point, that I couldn't really fathom how it good get any better.

What happened was this: the tonal balanced didn't really change at all, or it happened so imperceptibly that I can't tell the difference. But! The amount of detail doubled. Or tripled. Suddenly there is so much happening everywhere. So much air. So much detail. And it is a very smooth thing, too. There is no harshness to anything. You just find layers upon layers of texture in the instruments. The bass might be a smidgen more controlled than with the OPA2134, but it is very close. Layering is good and the sound-stage is respectably wide, but the upfront presentation doesn’t convey much depth. That’s perfectly fine in my book as no device near this price can’t really do much stage depth either. With the exception of the Fostex T50 MK3, the other headphones sounded good and loud enough. But with neutral bass oomph compared to the E10k. Yeah; this is a mains powered amp (rather than usb, or battery), that's one of the factors why I chose it. This is surely the (most) correct category.

Comparing the X6 with my 'proper rig', what i did notice is that the X6 is inferior in just about every way. But this is to be expected; I've got a little bit of pride, about my set up. Particularly the source. The first of them is a move to a Sabre ESS9018 DAC chip. The next one is the added Bluetooth connectivity that the original X6 didn’t possess. All the usual digital inputs are present too. To cut things short, here’s the full list of features:
