What is the latest greatest USB add on device?

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?

I find for USB cable add on i prefer iFi Audio iSilencer iDefender and iPurifier
 I also use a Pangea 1.5 meter Premier SE USB cable in my Mac Book Pro.

Thanks cincyjim5,

iFi and Pangea makes some very good performing cables and at affordable prices.

Merry Christmas!

I don’t understand all the hate on the USB Disruptor. I’ve read the computeraudiophile.com forum thread and personally I think the people on that thread that trash the Disruptor come off as complete ass***es. For $100 the USB Disruptor cleaned up the USB output from my computer to a NAD M51 DAC.

NOTE: I’m not an audio or computer noob. I am an enterprise IT architect and consider myself a fairly well informed geek when it comes to audio. The computeraudiophile.com thread where they gloat about banning the guy who sells the USB Disruptor reeks of lameness. If you’re gonna beat on someone for selling fools gold, how about the Totem Beaks?

Merry Christmas and great New Year, OZZY.
