Source is mostly Tidal HiFi where I listen to many different things - Pink Floyd, Metallica, Daft Punk, classical, jazz. I tried running the Jot through my Asus Xonar external sound card, but I can't actually tell the difference between that and the Jot's built-in DAC. Spending another 2-300...

Those are good suggestions; I'll try to experiment a bit before the return deadline. How long does it actually take to properly warm up? I sleep in the same room and the white LED is quite bright so it'd be nice to turn it off at night.

I received my Jot a couple of days ago to replace my old Fiio 09. I've been pairing it with my (also new) Sennheiser HD650s. Unfortunately, I'm really not liking the sound at all. The resolution, detail and soundstage are all much better than my Fiio, but I can't stand the highs. They literally...

Hello,   I've got a sort of mechanical problem with my DT-770 Pros - this is not directly related to how they sound. What happens is the metal bar-thingy which is used to adjust the size of the headphones scrapes against the curved metal-thingy (where the headphones rest on my head) and makes...

After a ton of reading and a trip to the music store I'm all but set on the DT-770, so I'm almost certainly going to buy those. Thanks for your feedback though!

Thank you for responding! I posted a question in that thread and got a good answer, so it's all sorted out.

Excellent! Thank you very much. I just picked up the sound card, gonna plug it in and play around with it. Too bad I still only have my crappy Fatal1ty headset.

Exactly, but I want to output Dolby from the Xonar into the E09K, and from there into my headphones. That's why I was thinking of plugging a 3.5mm jack into the Xonar headphone-out on the front. That cable would then connect to the back of the E09K, presumably by having RCA on the other end...

Okay, well I plead ignorance. Just want to be sure I'm not shelling out for something that's effectively useless for my purposes, but it seems like everything's in order. Would be strange if the E09K couldn't connect to a PC sound card, so it most likely can, and without any signal being lost.

Aha, I think your's differs from the E09K in that respect. Do you know whether anything happens to the signal in a 3.5mm jack -> RCA cable?

So your amp has a 3.5mm input on the back? 

How does your amp connect to the U7? The E09K has aux in, which I assume is the one I should use? I want to preserve the surround stuff the Xonar does, which means I have to use the Xonar's headphone out to connect the amp, but what do I then plug into the amp? To my knowledge the E09K does not...

I'm buying an Asus Xonar U7, and a pair of 250 Ohm headphones (DT770 or DT990, haven't made up my mind yet). The Xonar doesn't quite have the power to drive the headphones though, but I found a guy selling a used E09K. The question is, can I use the E09K as an amp and the sound card as the DAC...

Haha, glad to know there's an easy fix.  Sorry for going a little off-topic now, but there's something rather urgent I need an answer to: I found a guy selling a Fiio E09K QOGIR pretty cheap, so I would get that and pair it with the 250 Ohm DT-770, but I can't find anything about connecting the...

I found a guy who's selling a Fiio Qogir E09K that I'd like to pair with the U7 to drive some DT 770 or 990 250 Ohms, but I'd really like some fast feedback from someone who's using a desktop amp with their U7; is it a good idea? And can you turn the built-in amp off in the sound card? I imagine...
