A Better Bluesound AC Cable?

I replace all of my stock power cables and improved the sound on every components

I use the following...

- But with the C7 connector

The improvements were very noticeable and even better with the Helix interconnect.

Another tweak that worked wonders were placing brass cone feet (3 of them) under the Nore 2 and Power Node 2 units.

I have the Node 2, the PowerNode2 and the Pulse Mini speaker - all with the helix power cables and ALL sound  amazing

If you are NOT into DIY then checkout KE Innovations Power cables - they are very good and more reasonably priced than Nordost

IMO, lowering the noise floor will improve any component. In fact, I could see where you may get more "improvement" with power upgrades then stepping up super high priced interconnects (assuming you have well made interconnects). I'm not certain if $5000 power cables will reduce noise any more than a $200 well made cable, however, most component makers source their OEM cables from the same cheap, mass produced suppliers overseas. Chances are your $4000 amp has the the same power cable that a $99 Best Buy receiver has. 

I put an AQ power cable (forgot which model) in the Node. 
Heard absolutely nothing different.
