You should save your money and not buy the intona, iusb 3.0 etc. even the PPA3. I think the biggest difference I was getting was from the clean Paul Hynes SR3 and the Teddy Pardo. And the intona doesn't work miracles on my machine, but with others it's quite impressive. I found a small increase of sq in my system with the intona, that actually impresses me since i've found it difficult to find other upgrades that actually make a difference...not just a sidegrade.
I've never mentioned how much better the PPA3 is over the PPA2, Another guy in this thread has done that comparisons. Cthua or something, I forgot. I've read countless places that the PPA3 is better than PPA2, yet a few saying they are pretty close. Either way, they allow for the USB5v to be supplied from a separate Linear psu. that is key.
It's not the clocks that are creating the noise in the 8khz packets. All of the clocks, even the low performance ones are still low enough below the noise floor to not be issues. Also, alex Crespi mentions that the clocks, crystek, are far from the reason the regen performs. I can re-quote that email from him if you'd like.
I too made the mistake of thinking that usb clocks made a difference like masterclocks for spdif..

Hi Tim:
Your Teradak will work fine with the REGEN.
The REGEN will be of benefit to both the Gustard and the Amanero. It is all about providing better signal integrity (a real thing, not a marketing word) to the USB input so the DAC's USB input PHY chip (complex little beast) does not have to work as hard to decode the data, thereby generating less packet- and ground-plane noise. You might find some enlightenment about the issues and the REGEN in this review that was just published on AudioStream.com: http://www.audiostream.com/content/uptone-audio-usb-regen
As for clocks: You are confusing the DAC master clock (or the Gustard's output clock which becomes master for S/PDIF interfaces) with the USB PHY and hub-chip clock as used in all USB inputs and in the REGEN and Schiit Wyrd. VERY different things. We do use a nice low-jitter Crystek clock in the REGEN, but is far from being an important aspect to its performance--or the reason the REGEN outperform the Schiit Wyrd. The power network around our hub chip, the impedance matching with the 4-layer board, and the whole focus on SI is what makes the REGEN stand out--especially when placed right at the input jack of the DAC or USB>S/PDIF converter as recommended.
I am sure you will enjoy it.
Best,

So...intona is creating 60uV of noise from 20hz-22khz. not bad? better than most anyone's usb on average. but what's best is that the ground plane noise is absolutely eliminated. therefor the packet noise issues are too. Regen did a good job at attenuated some of it. but other issues arose too. Anyhow... like I said, it's not a miracle worker, i've never made any such comment as you say. For my machine at least.
Also, CMEMs clock is on the dirty side of the intona, the CLEAN side is re-clocking the signal via the usb chip with it's pll internal clock. Even if it was "ultra high noise", which it's not. It's just not ultra low noise. simply low noise is a fair way to describe them.
On a last note. this is just downright silly to have you comment on gear you've never actually tested yourself. The end test is listening for improvements, not just changes.
I've not experienced dramatic changes with the Graphene Extreme cables, but every so slight improvements that imho...thats awesome! but certainly not some magical pairing. I will try the breeze and graphene extreme as you say it's a good match. I expect to hear subtle change at most.
