Power cord upgrade

That depends on the Tornado model,  if you used the HC I can see that just too big for the application , I spoke with AQ engineers the geometries are different for the far less demanding Source products like Dac Streamers ,DDC Reclockers ,preamps , this is why they developed the Source Tornado. The Engineers offered this information without me asking them .they took the time to explain ,myself a technical person appreciated this. Perrotta Consultants has a Special pricing on these . 

DH Labs Red Wave or Furutech NCF.

The only thing you'll achieve by buying a new expensive power cord is having something that might look pretty compared to a standard cable. But besides that, you won't hear a single difference. You might actually be introducing noise. That's snake oil for ya. If you're not happy with the sound of something, check your room acoustics, make sure you have a capable amp, and/or replace your speakers. That's it.  Everything else is a waste of your money.

@squared80 You do have a valid point on the room acoustics but not on power cables. Guessing you have a lo to mid-fi system and should head on back to ASR. 

I originally had Nordost Red Dawn on my streamer then upgraded to the Tornado source cable. I just upgraded from that to a Snake River Audio cables. I bought 2 different ones. One is the Signature which is a hybrid of 24K gold and silver. The other is the Cottonmouth which is 24k gold. In my setup, the cottonmouth sounded better on the streamer and the hybrid on my phono. Couldn’t be happier with the results. Highly recommend giving them a look. (SRA runs some pretty good deals now and then).
