Choosing an amplifier starts with the system around it.
Speaker type, room size, source equipment and preferred listening formats matter more than the length of a feature list.
A compact integrated model can combine amplification, digital conversion and TV connectivity, while a dedicated power amplifier may offer greater output reserves but require a separate preamplifier. The products gathered here cover several distinct roles, including all-in-one stereo hubs, Class AB integrated amplifiers, dual-mono power amplification and desktop headphone systems. One entry, the Teac TN-5BB, is a turntable rather than an amplifier; it remains included in its supplied position but should be viewed as a source component that needs suitable phono amplification. Specifications should be interpreted in context. Power figures are only meaningful alongside speaker impedance and sensitivity, while input selection determines whether a television, turntable, computer or wireless source can connect without additional hardware. Use the distinctions below to identify the product type that fits your system before comparing output figures or design details.

Frequently asked questions
How much amplifier power do I need?
Start with the loudspeaker manufacturer’s impedance and sensitivity information, then consider room size and listening level.
Do not compare wattage figures without checking the stated load: an output specified into 4 ohms is not directly equivalent to one specified into 8 ohms.
Should I choose an integrated amplifier or a power amplifier?
An integrated amplifier combines volume control, source selection and power amplification, and may also include a DAC, phono stage or Bluetooth.
A dedicated power amplifier such as the Audio-GD MASTER-2A or Limestone PP1 needs separate source control and, in most systems, a preamplifier.
Do I need a phono input for a turntable?
You need a phono stage somewhere in the signal path unless the turntable has one built in.
The Teac TN-5BB has no internal phono preamplifier, whereas models such as the SMSL AL400, Michi X5 Series 2 and Technics SU-C700 provide phono connectivity; cartridge compatibility should still be checked.
Which connections matter for television and computer audio?
For a television, HDMI ARC or eARC can simplify control and cabling, as offered by the Tonewinner AD-60 and SMSL AL400 respectively.
For a computer, look for a compatible USB input; optical or coaxial connections may also work if the source provides them.
How to Match an Amplifier to Your System
Begin by deciding which product category you actually need.
An integrated amplifier is usually the simplest foundation for passive speakers because it combines source selection, volume control and speaker power.
A power amplifier or monoblock requires additional components, while a headphone amplifier with line outputs, such as the TANCHJIM VAST, is intended for headphones or powered speakers rather than conventional passive loudspeakers. Next, list every source you expect to connect. HDMI ARC or eARC is valuable when the amplifier will handle television audio. USB, optical and coaxial inputs support digital sources, while Bluetooth prioritizes convenience. Vinyl users must confirm both the presence and type of phono stage: MM support is common among the products described here, but the SMSL AL400 also supports MC cartridges. A turntable without a built-in phono stage, including the Teac TN-5BB, cannot be treated like a standard line-level source. Finally, match amplification to the speakers rather than choosing on wattage alone. Check power into the relevant impedance, verify that the speaker manufacturer’s requirements are met and leave room for normal listening peaks. Also consider practical details such as chassis size, ventilation, subwoofer outputs and headphone sockets. The strongest purchase is not necessarily the amplifier with the largest specification; it is the one whose role, connections and output align cleanly with the rest of the system.
