XLR to RCA adaptor

Hi, My new power amp has only RCA input and I use Tara Labs The 2 XLR for my previous power amp. I don't want to get another pair of interconnect. Are there any adaptor available in the market for such purpose? Thanks, Joseph

Both Rowland and BAT make (or at least sell) these. I am using a set of BAT's on my pre-amp to phono pre-amp. Seems OK. Alex
Purist Audio Designs, makers of the Purist cable make this adaptor, and it is excellent quality. Call the factory for dealer location.
