What the AI looks for in Audio Component Amplifiers
- Integrated vs power amp
- An integrated amp has inputs and volume; a power amp needs a preamp or a receiver's preamp outputs Buying a power amp alone leaves you with no volume control or source switching.
- Power into your speakers
- Match the rated power at your speakers' impedance; allow more headroom for speakers under about 87 dB sensitivity Speaker sensitivity matters more than the amp's headline wattage.
- Impedance stability
- The amp should be explicitly rated into 4 ohms if your speakers dip there Weak amps clip or protect-shutdown on demanding speakers.
- Inputs needed
- Check for a phono (MM) input for turntables, optical/USB for TV and PC, and a sub out for 2.1 Missing inputs force extra DACs or phono preamps.
- Class-D supply
- For small class-D amps, use an adequately rated power brick; many ship with an undersized one The supply often limits real output more than the amp chip does.
Brands that matter
- Yamaha: Durable A-S integrated amps with a classic layout.
- Cambridge Audio: AXA and CX integrated amps tuned for music.
- Marantz: PM-series integrated amps with a warm sound and strong phono stages.
- NAD: Conservative power ratings and good streaming options.
- WiiM: Streaming-first compact amps with excellent app support.
- Fosi Audio: Inexpensive compact class-D desktop amps.
- Emotiva: Value power amps for home theater add-ons.
- Rotel: Solid, neutral integrated and power amps.
What to avoid
- No-name mini amps quoting peak watts in the hundreds.
- Car-audio amps repurposed for home use without a proper supply.
- Bluetooth-only amps if you have wired sources.
Questions
Can I connect a turntable directly?
Only if the amp has a labeled phono input; otherwise you need a phono preamp or a turntable with a built-in one.
