Tornado and Thunder Power Cables

I see the EE above suggesting room acoustics and correction software.

This I totally agree with and encourage. A properly treated room will do more than any tweak or component swap, however room correction to me is a band-aid.

This band-aid is of limited value if any. Sure it can radically alter the sound but is it better? The reason for room treatment is all about reducing overly long decay to a certain level within a certain time frame which is dictated by the volume of the room. For that absorption is needed. Room correction software can not anticipate and reduce the decay and fill in the nulls resulting from cancellation. Consider that if you drive more power into a null it will just cancel with the same power.

Last bit of advice, promise 😁   Any room  treatment you consider adding and which I thoroughly recommend should prefereably be done first as you may be for example trying to tame a bright sytem by using 'warmer' cables etc. which will take you in the wrong direction. Room first will also allow you to better hear and choose the best for the job.

vanson1, you're wrong. 

I have Hurricanes throughout my system and can't say enough good things about them.  

Do you have a Niagara Power Conditioner?  If yes, AQ is superb.  If not, you may find that treble extension could be a challenge.  Particularly with Thunder.  This gets less pronounced if you rise a bit in terms of quality.  for example, Hurricanes, though those are much pricier.  

I would look at Clarus Crimson or Puritan Ultimate if you do not have a Niagara Power conditioner.  

To OP if your heart is telling you those tornado power cord will improved your system performance, audition them first, Music direct has 60 days trial, might as well try the hurricane too.
