If by phono cable, you mean interconnects....
I've been satisfied with Herron Audio cable. It's not that expensive but performs very well with his equipment. Haven't heard it with other equipment.
My experience is that if you're looking for warmth, remove all the cable from your system that uses silver and go with all-copper cable. My opinion is that silver adds an artificial treble peak and dries out the sound. YMMV.
