The dx90 doesn't go well with super bright or sibilant prone headphones but I feel that the sabre treble was significantly toned down via upgraded batteries (just a good samsung s3 battery will do) and the 2.1.0 international custom firmware by lurker.

Do I get to touch the door knob to check for heat?

Indiscriminately touching strangers' knobs isn't going to help you this time, I'm afraid.

Any DAP will sound bad with super bright and sibilant headohones. That's not the DAP's fault.
Is it even possible that the battery can alter sound? I don't see  how that could happen.

Edit: The dudes in the head-fi sound science forum agree that the jitter measurement is fine and the jitter should be completely inaudible.
I also don't see or hear anything that resembles glare. The 3rd order harmonic is 100 dB below the signal. Dunno how that could matter.

Unfortunately, we are not as smart as the dudes in the HF sound science forum in regards to understanding jitter. Here, we are still way way behind - trying to see if there's any correlation of subjective observations to measurements. Hopefully this will change in time with more jitter measurements of different gear being performed the same way with better measurement instrumentation.

Right now we are just playing with some of these measurements more out of curiosity than delivering the truth.
