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.

jaybe,

So did you get the external clock option?
I didn't but I did get the "Special Edition" which is supposed to have upgraded caps, wiring and EMI shielding.

So, I now have the ISO Regen connected to the output of the SOtM txUSB ultra SE with the supplied standard wall wart power supplies. (The Regen LPS 1.2's won't arrive till after the holidays). 

This combo sounds a little better than when I just used the USB Disrupter but frankly I was expected a lot more. 
Does the power supply with these devices really make that much difference?
