As for the upsampling features, I felt that it is not as clean as bit perfect. I prefer the upsampling is turned off. I don’t have the correct equipment to measure it. But from what I understand is it like video resolution, when you play 480p video on 1080p display, it will upscale to 1080p with the help of your GPU (upsampling). If use older or cheaper GPU, it will look washed out. If you use latest and more powerful GPU, the upscale will looks nice. For E1 upsampling it supposed to make the sound better, but it’s doesn’t seem to do job well or am I missing something here?

First of all, good review.

Second, I've never felt that there's a need for upsampling. All it does is simply pad 0s from a 44khz/16bit file into whatever it is being upsampled to, which in my experience has created clipping. It's the same thing when you set a sample rate in Windows.
So no, it doesn't make your music sound better.

Also, on a side note... your analogy on old GPU upscaling worse vs new GPU upscalling better isn't a good example I think.

Looking forward to your views on the STU.

I personally found it a little too cold and analytical. Instruments may at times sound a little metalic too.

1st thing I've notice that it not well balance and it not as clean as E1. Overall STU similar to STX, well I need sometime to play with it  smile.gif

u mean artificial? that's the characteristics of LME49720NA (stock STU), the sound same like STX (LME49720NA I/V)..but when replace with OPA2132PA it sound good actually.

Yup.
The STU is basically an external STX, couldn't differentiate them.

Was running it on stock op-amps, haven't had time to mess around yet.
