That's really good news as I was wondering if there would be a new product release soon but obviously Asus reps never know anything or they try to make us believe so as I've asked their chat and email support 2 weeks ago and they knew nothing (-_-). It doesn't surprise me with the STU that will be the lower-end model, the Essence One middle range and the Essence III their new high-end. I just hope it's not about 1000$ just because of some new fancy features that most of us will prolly not use. Anyhow it's good to know as I just bought an E1 and I have 30 days to return it so I will definitely send it back knowing that a better unit is on the way soon!
I've got a few questions however so far from my current use of the E1:
1- I get some very very small buzzing sound through my speakers when moving my mouse but it only happens if...
* My gaming mouse is set to 1000Hz. At 500Hz it's 2-3x less perceptible and not at all at 125Hz.
* If I move my mouse at 1000Hz on a darker background. If I open my browser and that it's all white, I get no buzzing at all.
* It only happens when using the E1 through USB.
* PS: I'm on the latest driver (220.127.116.11), Audio Chip Firmware (0111) but only the E1 Firmware (1.23) as I cannot update the MCU's firmware as when I open the program and click "connect" while in maintenance mode, it just won't connect... lame PoS!
2- What is the difference in sound quality if you're connected through SPDIF rather than USB? I think I read the E1 only upsample in USB but I'm not sure. I remember there was a limitation from spdif that usb didn't have but I can't remember what exactly. I use an (Auzentech X-Meridian 2G) with upgraded Opamps, what happens if I use the optical out from this card rather than usb?
