What is the latest greatest USB add on device?

I have been out of the USB arena for a while. Last I remembered there was an Uptone Regen, iFi, Intonia, Mutec, and the Disrupter.
I still own the Disrupter and I just tried it again and it did seem to improve the USB signal.
Is there any new USB devices that I should consider? It would be used between a Bryston BDP-2 USB player and a PS Audio Direst Stream Dac.

Well I received the (2) Uptone LPS 1.2 power units for my ISO Regen and SOtM usb.

So, now I hear that upgrading the DC power cables to star quad will also improve sound quality. 
Grannyring or any others, what do you think?

jaybe,

Uptone actually recommended the Ghents. So, I went an ordered 2 of them. $85 a piece including shipping is not all that bad.

Well the starquad DC does not come close to the more difficult to build Poe DC cable.  However they are much better than stock. 
@jaybe   @grannyring   Is the POE a diy build? Can you share more information on the construction? Thanks.
