Benzman - RE:
Probably may not make any difference in SQ but it could. :)
I’ve had lots of experience making power chords for everything from a $300 mini system to systems exceeding $70k.
My Mini system is in the garage and the new cables made a noticeable difference, even in the garage!
I also have one for my Bluesound TV soundbar speaker and the attached sub, and again - it made a noticeable difference.
Of course everything dependes on the quality of the cables
This one from Audio Envy should make a very nice improvement
You should hear a significant improvement in dynamics because they use OCC copper and their own cable geometry/insulations which will lower the noise floor and improve clairty and details
Unfortunately, not all power cables are equal, but Audio Envy are perhaps one of the best values for money on the market right now
Are they the best? - no, but they will sound better than most other well known brands on the market
Hope that helps - Steve.
