From product page, I excerpted this: www.sherbourn.com/collections/whole-home/products/pa1845========== PA 18-45 18-Channel Amplifier $719 Define up to 9 separate stereo zones with 40 watts per channel, all channels driven, or add more PA 18-45s or 12-45s as necessary to cover your whole house. ====== But From tech spec page, it says this: Power output (per channel): 45 watts RMS per channel (x18); into 8 Ohms; two channels driven. 70 watts RMS per channel (x18); into 4 Ohms; two channels driven. 40 watts RMS per channel (x18); into 8 Ohms; six channels driven. 140 watts RMS per channel (x9); into 8 Ohms (bridged) . =========== I have six pairs right now and will be adding at least four more speakers for a total of about 16. Currently using HTD digital amp and planning on buying this Sherbourn. HTD: www.htd.com/Products/multi-channel-amplifiers/DMA-1240Am I interpreting the two sets info correctly, i.e. that there seems to be a conflict of info? TIA. |

Not sure what the confusion is? 18 channel amp or 9 in bridge mode, with varying output (watts) depending on how hard you drive it.

The 40 watts rating into 8 ohms:
- 40 watts RMS per channel (x18); into 8 Ohms; six channels driven.
- Define up to 9 separate stereo zones with 40 watts per channel, all channels driven
I'll check with them in the morning. Besides, product page says it's unavailable.
Thanks.

I just re-checked the website and both the 12 and 18 channel (6 and 9 zone) versions are available now.
Does anyone have any experience with them? Or, any comparable options to consider from other places?
FYI, I am looking to replace the amp for my central home system that is currently fed by a Sonos ZP90. My current amp is an old Rotel 2-channel and it is currently providing power to 5 zones in my house with the amp outs being split to the various zones via a Radio Shack speaker selector box. I'm looking to reuse my Rotel elsewhere for 2-channel only.
Given this is for whole-home listening (in kitchen while cooking, in Great Room over dinner/sitting around, in hot tub, in master bedroom, in garage) - I am not overly concerned with audiophile sound. This is really for ambience music. So, the ultimate in sound is not required.
Note that another option I am considering is to completely ditch any stand-alone amp and getting 3-5 Sonos AMP's to feed all zones and be able to have independent choice of source in each zone. That's a lot more pricey option, but it's very flexible.

I picked up the PA 12-45 at the warehouse sale. Damon said, after taking a few moments to verify specs, that this amp should be able to power the UOM 6.2 and UAW 8.2.
My guess is that the PA 12-45 will be better compared to the HTD class-d amp for this 4 ohm speakers. We'll see as I'm also adding a pair of the rock speakers from that mono place and a pair of the 6.5 inch in ceiling.
At the warehouse price of the amp, it's certainly worth testing it.

If you are wanting separate zones, the Sonons would be a good option. The other system I would look at is the Nuvo wireless. You can control each zone independently or combine zones. There are lots of services already apart of the app and you can add your music from the network. Everything is controlled via an app that is designed pretty well. |

One thing that I would wonder is how well do these amps save electricity when not being used? That might be one advantage to a class d amp. These amps might shut themselves down when not being used.
I'm liking my IPS-1 for multiple zones as it turns on and shuts down each channel separately.

the closest thing i'd compare it with is a dennon poa power amp which is a 10 channel which bi-amps to about 280watts, closest comparison I would say would be a xpa-5 without bi-amp at 350, even the xpa-2 craps all over denon in bi-amp mode, and I might probably be cheaper using xpa-2's than running around with te poa, when you start start to compare wattage power..
leaving bi-amp alone for the moment, unless you have a post pre-amp to go from say 9-18 channels I see no point in using a multizone in context of a 2nd to ninth room unless it does a min of 5.1

After looking at the options and thinking it over, I'm thinking that I'll get 3 more Sonos Connect-AMP's so I an break up 1 big zone (Living room, dining room, kitchen, master bedroom, hot tub room) into 3 independent zones. Then, I'll take the Sonos ZP90 down to my home theater so I can have internet radio down there also. If I get the ProDac (which is likely), it will be fun to stream digital to it and see how that sounds. This also frees up my old Rotel to be used as a 2-channel amp upstairs to power my old B&W 202's (which are old but still sound quite nice!).
