Few things -
1. Be careful buying Furutech and Oyaide on ebay. Lots of fakes out there especially when it comes to Furutech.
2. The foundation of good bass is speakers, components and room acoustics. Replacing cheap power cables with other cheap power cables won’t give you what you want. Get your components and room acoustics done first then worry about cables.
3. Ignore @jasonbourne71 when it comes to cables.
Also, if you’re looking for people to make recommendations, it’s a good idea to list your components.
