Two channels, and everything spent on them
For television and music in the same room, a two-channel amplifier spends on quality what a receiver spends on channel count — and the modern ones have quietly acquired the connections that make that practical. The figures worth reading are power into 8 ohms and into 4: a design that nearly doubles between the two has a power supply that can drive difficult speakers, and one that states only 8 ohms usually cannot. Then the inputs: a built-in DAC with its supported sample rates, a phono stage and whether it is moving-magnet only, and increasingly HDMI ARC, which is what lets a television remote control the volume of a hi-fi amplifier. We compare stated power into 8 and 4 ohms, analog and digital inputs, DAC and supported rates, phono stage type, HDMI ARC, and headphone output.
In brief
We compare five stereo amplifiers on what each listing publishes. Four had an Amazon.com offer on October 25, 2026, from $56 to $1,200. On this shelf the power figures do not compare and the inputs decide: count your sources, check for a phono input if a turntable is one of them, and choose the US version where the European one carries a DAB tuner.
2 channels · Class D · 100 W × 2 stated · bass and treble controls · TPA3116 chipset
A compact Class D amplifier that names its amplifier chip — TPA3116 — which is unusual and lets the design be looked up rather than guessed at.
Best for: A desk, a small room or a second system, where size and cool running matter as much as the figure.
≈ $56
2 channels · 600 W PEAK · Bluetooth 5.3 · phono · optical · coaxial · USB · FM · 2 microphone inputs
A two-channel amplifier with an unusually long input list — including a phono stage — and a power figure stated as peak, which the page reports as such.
Best for: A room with several sources — a turntable, a television, a phone — where connection count matters more than measured power.
≈ $110
Stereo receiver · DAB tuner · Bluetooth
A stereo receiver rather than an amplifier — the difference is the tuner, and in a household that listens to radio it is the whole point.
Best for: A household that listens to radio daily and wants proper speakers rather than a compact system.
≈ $250
Two channel · HiFi stereo amplifier · Marantz house design
A two-channel amplifier from a house whose recent stereo models carry HDMI — the connection that lets a hi-fi amplifier sit under a television and be controlled by its remote.
Best for: A room where music matters as much as film, and where two very good channels beat seven adequate ones.
≈ $1,200
70 W per channel · integrated amplifier · Bluetooth
An integrated amplifier that states power per channel rather than as a total — the form that makes a two-channel figure meaningful.
Best for: A pair of real speakers and a household that listens as much as it watches.
No Amazon.com offer on Oct 25, 2026
A compact Class D amplifier is the cheapest way to power a pair of passive speakers. The lowest price here states its power per channel and names its chip.
One amplifier here states a phono input alongside optical, coaxial, USB and Bluetooth: it takes a record player without a separate preamp.
A stereo amplifier for two speakers and music; an AV receiver for surround and anything that arrives over HDMI. The Marantz Stereo 70s sits between the two: a stereo receiver whose US listing names HDMI inputs for a television.
Directly, only to an amplifier with a phono input. The Donner states one. A turntable without a built-in preamp plugged into an ordinary input plays far too quietly.
One hundred watts per channel, for two channels — the form that makes a stereo figure meaningful, unlike a total or a peak. Without the load (4 or 8 ohms) and the distortion at which it is measured, it is still a maker's figure, not a comparable one.
No: DAB is a European broadcast system. The Yamaha reviewed here is the European R-S202D; Amazon.com sells the R-S202, with an FM tuner, and that is the version to buy.
On October 25, 2026, Amazon.com had offers for the Fosi Audio TB10A, the Donner, the Yamaha R-S202 and the Marantz Stereo 70s. The Denon PMA-600NE had an Amazon.com product page with no seller.
On this shelf the power figures do not compare and the inputs decide: count your sources, check for a phono input if a turntable is one of them, and choose the US version where the European one carries a DAB tuner.
There is no table here, and the reason is in the listings. Enough of these 5 products name the same row — power — for a column to qualify, and too few publish a figure in it: the column would compare blanks rather than models. Each product page says what its own maker published.
Specifications: manufacturer sheets for home theater gear and the matching Amazon product pages. Prices and availability: Keepa.
