Unfortunately, the only way to get where you want to go is either a full blown Home Theater Processor or a AV Receiver. I don’t know of any 2-channel preamps that will do a "zone 2". The HT Processor or AV Receiver will replace your existing 2-channel preamp and will act as a source selector and volume control for both Zone 1 and Zone 2 speakers. You will need to supply an amplifier for Zone 2 if you choose an HT Processor (an integrated is not needed). Some AV Receivers can use other speaker outputs for Zone 2 (such as the "height speakers"). If you are still interested in this path, give us the following details and we can help guide towards a solution:
- What is your current model preamp/amplifier?
- What is your budget for this HT Processor / AV Receiver? This also decides the audio quality you will get out of this device.
- Do you have any specific video source requirements such as HDMI, 3D or 4K? Tidal, Netflix, streaming, DLNA?
You’ll have to replace your current preamp. The HT Processor route is the better way to go for sound quality and to keep your current amplifier. However, your budget may force you to do an AV Receiver if you want all the bells and whistles (4K, Netflix, tidal, streaming, etc.).
