I have the MF amp for my Spica's and a Carver for ACI Sub one's. I currently use a simple y adaptor out of my preamp. The MF amp has a set of jacks on the back called right and left loop out. Upscale Audio's website says they are for biamping, but my owners manual does not even mention them. Do I just run rca interconnects from the MF amp loop out jacks to the carver and eliminate the y adaptor? I don't want to risk any damage.
