Passive speakers, the kind with bare wire terminals and no power cord, need an amplifier, and the right one turns a pair of inherited bookshelf speakers or a thrift-store find into a proper stereo. The category has split in two: full-width receivers from Sony with phono inputs and real power, and palm-sized Bluetooth amps that cost less than a dinner out and drive a pair of speakers in a garage or an office. We ranked the stereo amplifiers and receivers in our audio catalog by rated power into real loads, the inputs they offer, Bluetooth and Wi-Fi streaming, speaker switching and tone controls, and what thousands of owners report.
We have not wired every amp ourselves; the verdicts rest on the spec sheets and the owner review history. Prices are not printed because they change daily; every button opens the live Amazon page. If you would rather buy speakers with the amplifier built in, our bookshelf speakers and stereo systems guide covers powered pairs, and for TV-first setups see home theater surround sound systems.
How we picked
- Drives passive speakers. Every pick has speaker-wire terminals; Bluetooth receivers that only feed a powered system are in a separate guide.
- Honest power. We quote RMS figures where the maker gives them and flag peak-only claims.
- Inputs that match real sources. Phono for turntables, RCA for players, HDMI ARC or optical for TVs, Bluetooth for phones.
- A spread of sizes. Full-width receivers and mini amps that fit a shelf.
- Owner ratings of 4.1 stars or better; every pick has at least 600 reviews.
The picks
Sony STRDH190 2-ch Home Stereo Receiver with Phono Inputs and Bluetooth Black
The Sony STR-DH190 is the receiver to buy for a turntable and a pair of real speakers, and 10,100 owners rating it 4.5 stars agree. It delivers 100 watts per channel into 8 ohms, has a built-in phono stage so a turntable plugs straight in, and adds four stereo RCA inputs, a 3.5mm jack and Bluetooth for phones. Speaker A/B switching lets you run two pairs, together or in separate rooms, and the 5.25-inch-tall chassis fits a standard cabinet. What it lacks is anything digital: no optical input for a TV, no HDMI, no Wi-Fi or app. Owners of vinyl setups rarely miss them; TV-first buyers should look at the WiiM. For a classic two-channel stereo at a sane price, this is the pick.
- 10,100 owner reviews at 4.5 stars, the most-trusted amp here
- Real 100W per channel and a proper phono stage
- A/B switching runs two pairs of speakers or two zones
- Four RCA inputs plus 3.5mm and Bluetooth
- No digital inputs: no optical, HDMI or USB
- Bluetooth only, no Wi-Fi or app
- Full-width chassis takes shelf space
WiiM Amp Streaming Amplifier for Passive Speakers with HDMI ARC, Silver
The WiiM Amp is what a stereo receiver looks like in 2026: a compact box that streams from Spotify, Amazon Music, TIDAL and Qobuz over Wi-Fi, receives AirPlay 2 and Chromecast, plugs into a TV over HDMI ARC, and drives passive speakers with 60 watts per channel into 8 ohms or 120 into 4. The WiiM Home app handles sources, EQ, presets and multiroom grouping with other WiiM, AirPlay 2, Echo and Google Home devices, and a subwoofer output is included. It has no phono stage, so vinyl needs an external preamp, and it cannot send AirPlay to other speakers. Owners rate it 4.6 stars across 2,335 reviews, the best rating on this page, and most pair it with a modest set of bookshelf speakers for a TV and music system in one.
- Wi-Fi streaming, AirPlay 2 and Chromecast built in
- HDMI ARC turns passive speakers into a TV sound system
- 2,335 owners at 4.6 stars, the highest rating here
- Compact box with a subwoofer output and app EQ
- No phono input; a turntable needs its own preamp
- 60W per channel is less than the Sony
- AirPlay receive only, cannot send to other AirPlay speakers
Moukey Stereo Receivers with Bluetooth 5.0, 2.0 Channel Power Audio Amplifier Stereo System w/USB, SD, AUX, RCA, MIC in w/Echo, LED for Karaoke, Home Theater Speakers, 400W Peak, 25W x 2 RMS- MAMP1
The Moukey MAMP1 is the budget mini amp with the biggest following: 4,980 owners rate it 4.3 stars, and it costs a fraction of the Sony. Moukey quotes a realistic 25 watts per channel RMS next to its 400W peak headline, which is enough for a pair of efficient bookshelf speakers in a bedroom, office or garage. Inputs are generous for the size: two pairs of RCA, two 6.35mm microphone jacks with an echo control, USB and SD playback, 3.5mm AUX, FM radio and Bluetooth 5.0. Bass, treble and balance knobs and a remote round it out. Owners mention microphone-jack hiss and the plastic feel, and nobody expects it to drive large floorstanders. As a first amp for a thrift-store speaker pair, it is the one.
- 4,980 owners at 4.3 stars, the most-reviewed mini amp
- Honest 25W RMS figure quoted alongside the peak
- Seven inputs including two microphone jacks with echo
- Tone controls and a remote at a budget price
- 25W per channel suits efficient speakers in a small room
- Microphone jacks add hiss on some units
- Plastic knobs and a basic LED display
Donner Bluetooth 5.0 Stereo Audio Amplifier Receiver, 4 Channel 440W Peak Power Home Theater Stereo Receiver with USB, SD, FM, 2 Mic in Echo, RCA, LED, Speaker Selector for Studio, Home - MAMP5
The Donner MAMP5 is the mini amp for a house with speakers in more than one room. Its four channels are controlled independently and a speaker selector lets you run up to eight speakers in four groups, so the kitchen and the patio can have different volumes from one box. Inputs match the Moukey: two RCA pairs, two microphone jacks with echo, USB, SD, FM and Bluetooth 5.0, with a display and remote. Donner quotes only a 440W peak figure, so treat real output as modest per channel and use efficient speakers. There is no phono or digital input. Owners rate it 4.2 stars across 2,840 reviews and the typical setup is ceiling or outdoor speakers across two or three zones; for that job nothing else here is as cheap.
- Four channels with independent control for two rooms or four zones
- Drives up to eight speakers
- 2,840 owners at 4.2 stars
- Two mic inputs with echo for announcements or karaoke
- Peak power only; no RMS figure quoted
- Bluetooth 5.0 range of about 40 ft
- No digital or phono inputs
WOOPKER AK45Pro Stereo Audio Amplifier,400W 2Channel Bluetooth 5.0
The WOOPKER AK45Pro is the mini amp to pick when the Moukey’s 25 watts feels thin: WOOPKER quotes 50 watts per channel RMS, enough for larger bookshelf speakers or a modest pair of towers in a normal room, while keeping the same desk-sized footprint. It takes Bluetooth 5.0, RCA, a USB stick, an SD card and two microphones, and has bass, treble, mic and master knobs plus a remote. The 400W-per-channel peak claim should be ignored in favour of the RMS figure. It has no optical, HDMI or phono input, like every mini amp here. With 612 reviews it has a shorter record than the Moukey or Daakro, but owners rate it 4.3 stars and typically use it for TV sound through passive speakers or a garage system.
- 50W per channel RMS, double the Moukey
- Bluetooth, RCA, USB, SD and two mic inputs
- Bass and treble knobs and a remote
- 4.3 stars at a budget price
- 612 reviews, fewer than the Moukey or Daakro
- Peak figure is marketing; use the RMS number
- No optical, HDMI or phono
Daakro AK45 Stereo Audio Amplifier 300W Bluetooth 5.1
The Daakro AK45 is the simplest amp here: a compact box with Bluetooth 5.1, volume, treble and bass knobs and a remote, sold at a price that makes it an easy experiment for a pair of speakers found in a closet. Daakro publishes a 300W peak figure and no RMS number, so expect output in the range of the other mini amps rather than the headline, and the listing documents little beyond Bluetooth for inputs. Its 3,460 reviews at 4.1 stars make it the second most-reviewed mini amp on the page, and the pattern in them is clear: it works and sounds fine for a bedroom or a workshop, the remote confuses people until they pull the battery tab, and buyers who expected hi-fi power are disappointed. Buy it for a casual Bluetooth setup, not as a main system.
- 3,460 owners, the second-largest review base among mini amps
- Bluetooth 5.1 and simple bass and treble knobs
- Remote included
- Very low price
- 4.1 stars; no RMS power figure is published
- Few documented inputs beyond Bluetooth
- Basic build and a remote with a pull tab owners miss
Facmogu 298A 2 Channel Bluetooth 5.0 Audio Amplifier 300W Wireless Amp
The Facmogu 298A is the least expensive amp here that still quotes an honest number: 40 watts per channel RMS, which Facmogu itself says suits a small apartment, bedroom, office or garage. Inputs cover Bluetooth 5.0, RCA, USB, SD card, FM radio and two microphones, with bass and treble knobs and a remote. Facmogu is unusually frank in its listing, warning that the microphone ports may hiss when idle and that the amp is for people who do not need anything fancy. Owners agree, rating it 4.1 stars across 1,860 reviews and describing a cheap, loud-enough amp for a workshop or a pair of outdoor speakers. If the budget is the entire decision, it is the floor of the category.
- 40W per channel RMS at the lowest price on the page
- Bluetooth, RCA, USB, SD, FM and two mic inputs
- Remote and tone controls
- 1,860 owners at 4.1 stars
- Maker admits microphone-port hiss
- Peak figure is inflated; 40W RMS is the real number
- Build and knobs feel cheap
Sony STRDH590 5.2 Channel Surround Sound Home Theater Receiver: 4K HDR AV Receiver with Bluetooth,Black
The Sony STR-DH590 is on a stereo page because many people buy an amplifier for two speakers today and wonder about a TV system tomorrow. It is a 5.2-channel AV receiver with four HDMI inputs and 4K HDR pass-through, optical and coaxial digital inputs, four stereo RCA inputs, Bluetooth and an FM tuner, and its S-Force PRO mode produces virtual surround from just two speakers. Run it as a stereo amp now and add a centre, surrounds and a sub later. It has no phono input, so turntable owners should pick the STR-DH190, and its HDMI spec predates 8K and the latest gaming features. Owners rate it 4.3 stars across 5,970 reviews and praise the flexibility for the money.
- Four HDMI inputs and 4K HDR pass-through
- Works as a two-channel stereo amp with virtual surround today, 5.2 later
- 5,970 owners at 4.3 stars
- Optical and coaxial digital inputs the stereo Sony lacks
- No phono input
- Larger and costlier than the STR-DH190
- Older HDMI spec; no 8K or HDMI 2.1 gaming features

Peak watts versus RMS watts
Mini amps advertise peak figures of 300 to 440 watts that describe a millisecond burst, not sustained output. The useful number is RMS, and only some makers print it: 25 watts per channel for the Moukey, 40 for the Facmogu, 50 for the WOOPKER, 60 for the WiiM and 100 for the Sony STR-DH190. The Daakro and Donner publish only peak figures, so assume they sit in the same 20 to 50 watt range as their peers. For bookshelf speakers of normal sensitivity in a normal room, 25 to 50 watts is plenty; for towers or a large room, or to avoid clipping at party volume, the Sony or WiiM are the safer buys.
Which inputs do you actually need?
A turntable without a built-in preamp needs a phono input, and only the Sony STR-DH190 has one here. A TV needs optical or HDMI ARC: the WiiM has both, the STR-DH590 has HDMI and optical, and no mini amp has either, so a TV would connect through its headphone jack if it has one. Phones connect over Bluetooth to every pick, and the WiiM adds Wi-Fi streaming with far better quality and range. CD players, cassette decks and game consoles with analog outputs use the RCA inputs that every amp here provides. Microphone inputs on the mini amps are a karaoke and announcement feature rather than a hi-fi one.
Full-size receiver or mini amp?
The two Sonys and the WiiM are the amplifiers to build a system around: real power, real inputs and a track record. The mini amps are tools for a specific job, such as a garage, a workshop, a patio or a second room, where their size and price matter more than their limits. A sensible path is a mini amp to try out a pair of inherited speakers, then the STR-DH190 or WiiM once you know you listen enough to justify it. Whichever you choose, pair it with speakers from our bookshelf speakers and stereo systems guide, matching impedance within the amp’s stated range.
Do I need an amplifier for my speakers?
Only if they are passive, with bare wire or binding-post terminals and no power cord. Powered or active speakers have an amp inside and plug into the wall. Every amp here is for passive speakers.
Which amplifier works with a turntable?
The Sony STR-DH190 has a built-in phono input. For the WiiM Amp or any mini amp, use a turntable with a built-in preamp or add an external phono preamp between the turntable and an RCA input.
Can I connect my TV to a stereo amplifier?
Yes with the WiiM Amp over HDMI ARC or optical, or the Sony STR-DH590 over HDMI or optical. The STR-DH190 and the mini amps have only analog inputs, so the TV would need a headphone jack or an optical-to-analog converter.
How many watts do I need?
For bookshelf speakers in a room up to about 300 square feet, 25 to 50 watts RMS per channel is enough. For larger rooms, tower speakers or loud listening, 60 to 100 watts from the WiiM or Sony STR-DH190 gives headroom.
What does 4 ohm and 8 ohm mean?
Speaker impedance. Most home speakers are 8 ohms or 6 ohms; some are 4 ohms and draw more current. The Sony STR-DH190 supports 6 to 16 ohms, the WiiM Amp 4 to 8 ohms and the Donner 4 to 16 ohms. Check your speakers before buying.
