Iam glad I bought this Cables.i have phono Cables ordered.I use Teo audio cables, Tellurium q Cables diamond Speaker Cables, Nordost heimdall 2 Speaker Cables, Palladian kimber pc as well. Cerious Cables, Hi fidlelity Cables. The audio envy cables on my system , I felt it brings the best of out my expensive cables.
