For almost two years, I have used an ARCAM AV9 controller, an ARCAM DV79 disc player and an (Audio Research) ARC 150M.5 amp for both film and music. My main speakers are Wilson Sohpia 2's with ProAc speakers filling out the remaining spots. Recently, I incorporated an ARC LS26 preamp and an ARC CD5 into the system for two channel music.
My question centers around the continuned use of the AV9 within this system. The AV9 does not have balanced connections so I use unbalanced RCA terminated interconnects to link it with the LS26; however, I use balanced interconnects or XLR's from the LS 26 for connecting to the CD5 and to the 150M. An AV dealer suggested trading out the AV9 for a controller that provides balanced connections for a more coherent system. He suggested a B&K Reference 70, but I am not familiar with it and, because it is quite new, cannot find much in the way of reviews.
Because I subscribe to TAS and read TAS reviews, I know that the editors and I assume some readers are familiar with the ARCAM AV9 and the ARC 150M.5 and some products from B&K. Does it make sense to switch to a new controller, and, if so what are some appropriate alternatives---the B&K, etc? Thanks for some thoughtful suggestions.
