Mogami is what I use with or without my Atma-Sphere amp. Their RCA cable are very good too. For XLR you do want the Studio Gold Neglex Quad.
I have used Grover Huffman cables as well and they are also very good. Cost more than Mogami, but use ribbon conductors instead of stranded. They come with a generous trial period so you have nothing to lose but time and postage in giving them an audition.
