So, I have a house that is wired for 5 zones of speakers, 1 pair of speakers per zone--and I need help with selecting the hardware.
The way I see it, there are four different operations for the hardware to perform:
1. Source selection and main volume control
2. Converting from stereo to mono (for at least some of the zones, if not all)
3. Pre-Amp: Volume control for each zone (including On/Off)
4. Power Amp
I see several different options:
Option 1: Sonos Power Amp (new version) for all 5 zones.
- This is an elegant solution with high power capacity, and it even provides Operation 2 above (i.e. conversion to mono), but it is very expensive at $600/zone equals $3000.
- It is also very costly to upgrade, as any upgrade would require a full replacement of everything. (Note that the piece that will require upgrades the most will be the Source Selection operation, as that is the most prone to changes in technology. Everything else should last for decades.)
Option 2: Sonos Connect: Amp for everything.
- This is less expensive ($400/zone equals $2000) but is already old.
- It's also much lower power (probably not an issue)
- It also does not perform (or even allow for) conversion of stereo to mono--at least not at the line level.
Option 3: Sonos Connect for Item 1, Home Theater Direct (HTD) for everything else.
- This costs $350 for the Sonos, $500 for the pre-amp (the mid-level version plus the Ethernet to serial module), and $800 for the Amp -- equals $1650
- Note that even though the HTD Amp will mix stereo into mono, it will only do it for the two "line" inputs. It can't do it for the separate zone inputs, which are required when using the Pre-amp to adjust volume for each zone.
- It's not quite as elegant of a solution because you need two separate Apps for control -- the Sonos App for source selection and main volume and the HTD App for volume in each zone.
- It's much easier to upgrade, although I have my doubts are to whether or not Sonos will actually upgrade the Sonos Connect. My guess is that they will want to push everyone into the new Amp.
Option 3B: Same as option 3 except use a small mixer/combiner ($100 or less) to mix the stereo to mono at line level right after it leaves the Sonos Connect. Total cost: $1750
Do you have any other suggestions---both for overall design and for different hardware to use?
Thanks!
