Sonos Amp Reviews

Beautiful performance

These Sonos products are great

Nice upgrade from Gen 1 Connect

By dvd
Rated 5 out of 5
Date: 2024-09-21

Moved in to a house with a nice Gen 1 system - 5 Connect amps hardwired to passive speakers in almost every room of the house. Loved that system, but it was pretty limited by contemporary standards. Biggest thing was no AirPlay with Gen 1. Recently took advantage of the Sonos upgrade deal for a very nifty discount on 5 Amps, 1 Port, and a Roam 2. The sound quality of the new Amps is noticeably superior to the Connects. AirPlay is essential. I also love the mono setting for one of our rooms where stereo just never sounded right. Great upgrade, worth every penny.

"Adjustable bass and treble controls let you adjust your sound performance. Volume can be adjusted". These words are right from the description. But I don't see these controls on the device. How do I do these adjustments?

Can I use my Bose 161 speakers with this amp as they are rated at a max of 100w?
Asked by: Scott
You are able to use it, you just would not want to turn the volume at max. This could then blow out the speakers.

Does it works with turntable

Does it works with turntable
Asked by: Manish
The Sonos Amp 250W Stereo Power Amplifier will work directly with a turntable that has a built in phono preamp. If the turntable does not have a built in phono preamp then you will need a phono preamp between the turntable and the Sonos Amp, like BH #BEVP549 or B&H # ROVP29 for example.

can we coonect this to the preout of denon x4500H or x3600H ?
Asked by: Mohammad Bayzed
Yes, you can connect to one of the zone pre amp outs, or if you're going to use this to power rear speakers you can come out the surround pre amps. You have quite a bit of flexibility with the Denon receivers.

can I use my Music Hall 5.1 turntable directly into this unit? So the Q is... does the AMP have phono pre-amp?
Asked by: ronald
No, this amplifier does not have a phono stage pre-amp. You would need a dedicated phono preamp. Music Hall makes some very high quality ones to go with their turntable. Such as, the Music Hall Bellari vp130 mk2 Tube Phono Preamp with Headphone Amplifier for Moving-Magnet Cartridges. https://www.bhphotovideo.com/c/product/1483524-REG/music_hall_vp_130mk2_tube_phono.html

What is the minimum acceptable impedance for the speaker output. (Can I connect four 8 ohm speakers?)
Asked by: Robert
The Sonos Amp 2.1 allows for two speakers up to 125 watts at 8 ohms, plus a subwoofer to be connected. In order to connect four speakers, you would run them in parallel, two on the left and two on the right, and each speaker would operate at 4 ohms. The total wattage the speakers should require is 125 watts per side. So each speaker should be rated 60 watts or under at 8 ohms, in order for this amp to power them safely.
