Measured performance of the FX-Audio DAC-X6 is rather disappointing. It loses to similarly priced Fiio E10K and by a larger margin to Topping D30. Do you guys have the same issues? Is it only me that the RCA outs increases the active speakers' volume a lot? 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.

If they're bypassing the volume control, then I'd guess that they're bypassing the X6 dac/amp combi's amp section, altogether. The output is straight from the DAC part.This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded. 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.

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.

You can find that thread here. 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.I've got another 'proper' rig, for my 'serious' listening. This dac-amp combo is just for computer media usage; mainly films, series, youtube etc. I would normally just plug straight into the laptop, for this. But the laptop's sound has a problem (thankfully only in the analogue domain). I have to use USB audio, now.

My headphones, the Beyerdynamic DT 770 Pros have a V shaped sound curve, with slightly recessed mids and higher treble and bass, meaning that they are quite bright headphones.
