Mini stereo amplifiers had a quiet renaissance in 2025 and 2026. The new Topping, FiiO, WiiM, and Cambridge Audio units pack streaming, Bluetooth, headphone amplification, and clean Class D power into a compact box. The catch is that none of them work well without a companion app. The hardware keeps getting better, the apps keep being the part that frustrates listeners on day two.
We tested 7 Android apps that pair with the most common Bluetooth and network-enabled stereo amplifiers. Pick the one that matches the gear in the rack. Most listeners end up with two installed, because brand-specific apps cover their own gear best, while a couple of universal players handle everything else.
What to look for in a stereo amplifier app
- Source switching that surfaces the inputs the amp actually has, not a generic menu.
- A real EQ, ideally parametric, with presets that persist across sessions.
- Stable Bluetooth and Wi-Fi reconnection. Stereo sessions are long, drop-outs are unforgivable.
- A multi-room story when there is more than one zone on the network.
- Hi-res streaming support that includes the codec the amp can actually take. LDAC, aptX HD, FLAC, DSD.
- A way to control volume from the phone without unlocking it. Notification or shade controls.
- Optional integrations with Roon, Apple Music, Tidal Connect, Spotify Connect.

1. HEOS, best for Denon and Marantz
HEOS is the official controller for Denon and Marantz HEOS-branded amplifiers, receivers, and speakers. Source switching, multi-room grouping, and full integration with Spotify Connect, Tidal Connect, Amazon Music HD, and TuneIn are all built in. The app is stable, the latency to the amp is low, and the EQ controls match the amp’s settings menu exactly.
Where it falls short: it only talks to HEOS-enabled gear. Non-HEOS Denon and Marantz pieces need the older AVR Remote app.
Pricing: free.
Platforms: Android, iOS, Windows (Spotify Connect via the amp).
Download: Google Play · Aptoide
Bottom line: the right pick if the rack has a HEOS badge. Skip otherwise.
2. Sony Music Center, best for Sony amps and receivers
Sony Music Center is the controller for Sony STR receivers and matching Sony speakers. The DSP and sound field settings show up cleanly, and the multi-room grouping works across most current SongPal-compatible Sony gear.
Where it falls short: non-Sony gear is invisible. The Bluetooth pairing flow occasionally takes two attempts.
Pricing: free.
Platforms: Android, iOS.
Download: Google Play · Aptoide
Bottom line: the right pick when the amp says Sony. Not useful past that.
3. Bose Music, best for Bose-branded systems
Bose Music is the polished, opinionated controller for Bose Soundbar, SoundLink, and Smart Speaker products. The grouping is the strongest of the brand apps, the voice assistant integration is genuinely useful, and the interface gets out of the way fast.
Where it falls short: the EQ is a three-slider affair, not a proper parametric. Bose hardware is the only target.
Pricing: free.
Platforms: Android, iOS.
Download: Google Play · Aptoide
Bottom line: the obvious pick for a Bose-only setup. Polished, but limited to its ecosystem.
4. FiiO Control, best for FiiO desktop and portable amps
FiiO Control is the controller for recent FiiO desktop DACs, headphone amps, and portable USB amps. Switching between EQ presets, toggling balanced output, and updating firmware all live in the app. It is small, clear, and does exactly what the gear needs.
Where it falls short: it is a single-zone, single-device tool. There is no streaming layer.
Pricing: free.
Platforms: Android, iOS.
Download: Google Play · Aptoide
Bottom line: the right pick when there is a recent FiiO product in the chain. Worth installing even if the playback app lives somewhere else.
5. BluOS Controller, best multi-zone audio
BluOS Controller is the controller for Bluesound and NAD’s BluOS-enabled amps and players. Multi-zone hi-res audio is the headline feature, and the streaming service support is the deepest of the brand apps. Tidal Connect, Qobuz, Spotify Connect, Apple AirPlay 2, Roon Ready.
Where it falls short: it only talks to BluOS hardware. The Android tablet UI is functional but not as refined as the Bose app.
Pricing: free.
Platforms: Android, iOS, Windows, macOS.
Download: Google Play · Aptoide
Bottom line: the right pick when the system is built around Bluesound or NAD BluOS amps. The multi-zone story is the best on this list.
6. WiiM Home, best for budget streamers
WiiM Home is the controller for the WiiM Pro, Mini, and Amp range. The PEQ controls, automatic room correction, and a sane streaming layer make the budget WiiM Amp punch well above its weight. Tidal Connect, Spotify Connect, AirPlay 2, and a clean PEQ that survives reboots.
Where it falls short: WiiM-branded hardware is the target. The library browsing is utilitarian compared with Audirvana.
Pricing: free.
Platforms: Android, iOS.
Download: Google Play · Aptoide
Bottom line: the right pick when the rack has a WiiM Amp or a WiiM Pro. The PEQ and room correction make it worth installing.
7. Audirvana Studio, best brand-agnostic high-end library
Audirvana Studio is the high-end music library and streaming bridge for serious listeners. It indexes a local library, integrates Qobuz and Tidal, and pushes to a UPnP, DLNA, or Chromecast-capable amp. The app respects bit-perfect output to a degree most amp companion apps do not.
Where it falls short: paid only, and the Android client is newer than the desktop. Some legacy network protocols still need the desktop app to drive them.
Pricing:
- Subscription from around 8 USD per month or 70 USD per year.
Platforms: Android, iOS, Windows, macOS.
Download: Google Play · Aptoide
Bottom line: the right pick when bit-perfect playback to an amp from a phone matters more than brand-specific control.
How to pick the right one
- For Denon or Marantz HEOS amps: HEOS.
- For Sony STR receivers: Sony Music Center.
- For Bose Smart Speakers and Soundbars: Bose Music.
- For FiiO desktop or portable amps: FiiO Control.
- For Bluesound or NAD BluOS multi-zone setups: BluOS Controller.
- For WiiM Amp or WiiM Pro budget streamers: WiiM Home.
- For brand-agnostic bit-perfect playback to any UPnP or DLNA amp: Audirvana Studio.
Most listeners end up with one brand-specific app and one universal player. HEOS plus Audirvana is a common pairing in 2026. WiiM Home plus Audirvana is the budget-conscious version that still gives a serious listening experience.
FAQ
Do I need a brand-specific app, or is one universal app enough? A brand app handles input switching, EQ, and firmware best. A universal app like Audirvana handles the library and streaming better. Most setups need both.
Can I control an old Bluetooth amplifier from Android? Basic playback works through the system Bluetooth controls. Codec choice and advanced settings need the amp’s companion app if one exists.
What is the best free app for stereo amplifier control? HEOS for HEOS-branded amps, WiiM Home for budget streamers, and BluOS Controller for Bluesound and NAD. All three are free.
Does Tidal Connect work on most stereo amps? On most current network-enabled amps, yes. Older Bluetooth-only amps need the brand app to bridge the connection.
Can I use one app across two amp brands? Only Audirvana spans brands cleanly. The brand-specific apps stay inside their own ecosystems by design.
