My big concern is not to purchase something that will choke off/ bottleneck the overall sound quality.
Well - Furutech is one of the few companies that has a line of unfiltered distribution bars
Pricey - but extremely good
Take a look at http://www.furutech.com/products/power-distributors-filters/
I made my own for much less, but I would not recommend this unless you are a serious hobbyist or in the electrical field.
