I have a Sonos system comprised of 4 listening areas. I recently added a turntable, and shortly will be connecting a hard drive or NAS with all of my digitized CD’s for ease of play and organization. Here is my current home set-up.
Area One area has a Sonos Port connected to a vintage Sansui AU-D9 integrated amplifier/TV/my own speakers.
Area Two has a Sonos Port connected to a Pro-ject turntable-turntable preamp and a Marantz 7025 Power Amp or NAD C268 Power Amp.
Area Three has a Sonos Amp connected to TV/my own 4 speakers, and,
Area Four has 2 Sonos One speakers.
I’ve been considering a Preamplifier to use with the Power Amps in Area two. Would I need a dedicated Preamplifier in this set-up, or would my Sonos Port App function as the Preamplifier? In what situations (if any) would a dedicated Preamplifier be a good choice to add to my system?
