So, curious, I have 2 450s and one has the noise with TF10s while the other doesn't. There's something strange here.

Model numbers?

I did notice a sonic difference between two 450s at the last meet but found out it was temperature related once the more strident one got warmed up.

They're at home and I'm in an airplane with the 720 and my HD800s in my bag.

So, LH got the first few batches of the ESS mobile chip line and ESS is notorious for being opaque with the product. There might be some weird production variant.

I've had two 450 units and they were not the same with regards to noise. One was silent with UERM while the other I can hear the the noise.

My early unit was silent and the recent unit is the noisy one.

Same. Early unit silent. New, retail package unit sounds like aliens are beaming encrypted messages into my brain.

As for noise, I didn't notice anything with the UERMs  on the 450 but they aren't 535s.  I can check later with my ES5s.

Thks I haven't any Windows on the hand to test it against my Ubuntu.  Volume management seems to be awful:  Software volume settings is not kept by ALSA or PULSE AUDIO , Hardware settings are always back to full power , sometimes the sound disappears  (but not the Noise) ...  A very dangerous little piece of crap .

Sadly when  I tried ( very carefully with my hand on my IEM in order to pull out them out of my ears quickly) it seems to sound good.

Jeez... how this thing can be legally sold ? it's a noisy lethal weapon .

I think my eardrums were damaged at least three times with my GO yesterday. For apparently no reason, the indicator lights went berserk; it showed the music as DSD 3x (when I was playing 16/44.1) and then the volume went way down and then screamed all the way up. Man, that is indeed a lethal weapon. Each time, I was playing it through my MBA with Amarra v3.0.2. Now I'm beginning to doubt whether the Amarra may be buggy to cause this.

Despite this happening a few times with my GO 450, which pissed me off to hell and back enough to sell them off,  and once with my current 720,  I have my fingers crossed that a new firmware that is planned to repurpose the two physical volume buttons as 1)On/Off 3D enhancer; 2) On/Off digital filter respectively.  That's all fine and dandy if and when that happens. 

Still puzzled with the two outputs and wish that the lowest output was hiss free, at least with my UERM.  I guess that's where the GO 100 comes in, no?  Anyone have in en route or plan to get one?

An update, I have the GO100, no noise. Thing goes berserk when I plug out the line out to plug in my IEM but not volume/DC bursting. Sometimes the device becomes unrecognized when you plug it in and out. Keep the drivers on hand for that to remove and reinstall if that happens.

Sound wise this is pretty amazing for the price I got it for($119). Minumum phase is pretty full bodied. Sounds harsh on warmup as the clocks are not fully set in. FRM filter clips badly out of the box(distortion reaches -40 or -30dbFS) but settles in though still looks bad compared to the TRM filter, looks like a firmware fixable issue.

Out of the box jitter looks bad, there is no difference between 16bit and 24bit data as its all swarmed with noise, the clocks or something needs warmup. Sounds harsh too before full warmup.



After it warms up the harshness disappears together with the jitter.
