Power Cable Suggestions Needed

You can’t just buy a cable based on random recommendations from a forum. You have to hear how any given cable will interact with any given component, and the only way you can do that is by listening. Find a good dealer or dealers who stock a range of power cables in your price range and home demo them.

You may end up paying a few bucks more than if you mail order, but in the end you have something that works in your system, and peace of mind knowing that you made the right choice.

Ever consider building your own?

FWIW I built my own with Furutech components. I had a lot of fun doing it. I was able to get just the right lengths for everything. They look great I might add.

I don't know your system, but if you are looking to clean up the bass, I would first look at repositioning your speakers, or putting some spikes or another type of feet to support them.  What speakers are you using and how are they positioned/supported?
