If it doesn't jeopardize the sound quality or create problems for the equipment, I would like to toggle the signal between two preamps going into a stereo power amp.
One preamp is for dedicated 2-channel, the other preamp is the front left/right pre-out from my surround receiver.
Currently, I manually switch the audio cables. Is there a quality switch box out there that doesn't add too much impedance, noise, etc. to the signal? I would like to simplify this process if possible. Thanks in advance for your suggestions.
