OK source to Pre amp/integrated are Tara labs spectrum 2a's with Tara lab RCS jumpers from pre to main in the integrated. but for the pre out to the power ampi have a supra EEF-1 Ok the second amp is powering the bass while the integreated is doing the upper ranges on the 703's But i was wondering about the cables.. would you go tara labs to replace the Supra? i have no issues with the sound as such but i wonder if anyone had a comparative test of the two brands?
