ohm rating is not a good gauge for how much power a headphone needs. K701s and the like are only 62ohm or so, and they are VERY hard to power. Likewise planars like the HE-6 are like 40ohm. They can't be driven by anything but the best amps.
I can only speculate, but looking at the BTR3, that thing is woefully small. I have no doubt it can't drive a beefier headphone properly at all. The X1 may not be hard to drive, but perhaps a weaker amp signifies a smaller soundstage and weaker bass. Signs of being underdriven.
As for the Mobius not having Apt-X, I know the reason, and I'll just say they're forward thinking and they have specific reasons why they aren't going that route. Apt-X may make sense now, but in the future for high end audio, it may not be so.
When something says up to 600ohm, it just means "They'll get sound". It does not mean, it will be ideal for something harder to drive. You have to look at how much power an amp pushes at the ohm rating. And that's not even all. There is sensitivity as well, which may be low or high regardless of ohms. I'll say the E5 is not an ideal amp for 600ohm. No way it has ample power there. When you think of 600ohm, they are naturally reserved for studio/desktop amplifiers. Not some portable thing you can hold with your hand.
If I get the Audeze Mobius, can you recommend a transmitter for LDAC?
