I use AZ Silver Ref MkII from source to pre and Matrix Ref MkII from pre to amp. This achieves a nice balance of resolution and warmth. However, using 2 Silver Ref cables, I personally would not recommend. But if you want warm, yet detailed, consider AZ Matrix Ref MkII. Hybrid copper/silver interconnect. If you find that to be splashy, which I doubt, try some Audioquest cables, like Jaguar or Panther. Little darker sounding, but if you like that, these'll do. Good luck.
