I currently have a great stereo set up for two channel listening using tube technology etc. Is there a switching device which can utilize an additional surround sound IR for HDTV only, bypassing my tube amp when in HDTV mode , that will also power my main speakers to a 5 speaker channel application. I do have an AR Sp16 preamp that can probably handle the proposed configuration. I do not want to give up the stereo capabilities of my VS110 amp as the sound for stereo listening cannot be duplicated with an IR, I have tried to attempt this with poor results, believe me.
