Denon HEOS Amp HS2 Streaming Integrated Amplifier, Silver

The Denon HEOS Amp HS2 is a streaming integrated amplifier that combines a built-in 2-channel power amp with HEOS network streaming in a compact housing.

Unlike the HEOS Link HS2, this unit needs no additional amplifier: connect the speaker terminals, connect to the network, done. For any room with passive speakers and no amplifier yet, the Amp HS2 is the most direct route into the HEOS multiroom system.

Why the HEOS Amp HS2?

Because it does the job of two devices in one: amplifier and network player. 2×100 watts at 6 ohms drives a wide range of passive bookshelf or floorstanding speakers, while HEOS Built-in brings streaming services, internet radio and music from your own server to the living room, the wine cellar or the workshop. A subwoofer output rounds off the system at the bottom end.

If you already have a HEOS Link HS2 or a HEOS Home device in the house, simply add the Amp HS2 to the group – in sync across several rooms, or with its own music per zone.

What you hear and get

Hi-res playback up to 24-bit/192kHz (WAV, FLAC, ALAC) and DSD up to 5.6MHz, plus AirPlay 2, Bluetooth and voice control via Alexa, Google Assistant or Siri. Internet radio and local network files run completely without a paid subscription – streaming services remain an option.

Who is the HEOS Amp HS2 for? (and who isn't it for)

Perfect for second and third rooms, kitchen, office or garage, where passive speakers should be set up without a large integrated amplifier taking up space. Straight talk: for a demanding main living room with high power needs or a preference for tube sound, a dedicated integrated amplifier is usually the more honest choice – the Amp HS2 plays to its strengths where compactness and multiroom integration matter, not as an audiophile flagship.

Our verdict

The HEOS Amp HS2 is the pragmatic all-rounder for the second and third room: connect the speakers, connect the network, and the music plays – with the same controls everywhere as in the main room. Anyone building a HEOS system will find the most straightforward building block for it here.

What the trade press says: "The Heos Amp HS2 is the perfect complement to the active speakers in the series. In terms of flexibility and ease of use, the bar for small streaming systems is raised another notch." – hifitest.de, 2017.

Frequently asked questions

Can I connect passive speakers directly to the HEOS Amp HS2?
Yes. The built-in power amp delivers 2×100 watts at 6 ohms and drives passive bookshelf or floorstanding speakers between 4 and 16 ohms directly via the speaker terminals – no additional amplifier or separate power amp is needed for this.

Does the HEOS Amp HS2 have a headphone output?
No, the unit has no headphone output. It's consistently designed as an amplifier for passive speakers, not for direct headphone use – anyone wanting to connect headphones needs a separate device with its own headphone output.

Can I connect a subwoofer?
Yes, an active subwoofer can be added via the RCA subwoofer output – handy if the connected speakers could use some bass support, for example in a larger room or with compact bookshelf speakers with limited depth.

Does the HEOS Amp HS2 work without a streaming subscription?
Yes. Internet radio, USB sticks and music from your own network server play completely without a subscription, once the unit is set up. Tidal, Qobuz or Spotify are a welcome option, but not a requirement for everyday operation.

How does the HEOS Amp HS2 differ from the HEOS Link HS2?
The Amp HS2 has a built-in power amp and speaker terminals, the Link HS2 doesn't – it's a pure preamp for an amplifier you already own. If you don't have your own amplifier yet, go for the Amp HS2; if you already have a good one, go for the Link HS2.

Why buy the Denon HEOS Amp HS2 at HD Zürisee?
Because a multiroom system is only as good as its planning: which speakers suit 6 ohms, how many zones make sense, how do you set it all up together via the app? We're with you every step – in business for years, with our own technician Mauri for on-site installation.

Goes well with

The Amp HS2 works best with matching bookshelf speakers or compact floorstanding speakers, plus a subwoofer for the foundation. For further rooms, you can extend the system with additional streaming speakers from the HEOS range.
