I used a Mogami XLR as an interconnect between preamp and amp for a short period. While it worked, it sounded more than a little thin and metallic to me. As soon as I replaced it with a Harmonic Technology Truthlink Silver, it was obvious that it was MUCH better than the Mogami. As always, your mileage may vary, but for my money, I think it's smarter to purchase used cables elsewhere. I like Zu for about the same price as the Mogami, or for a little more Harmonic, Tara Labs or Acoustic Zen.
Good luck.
