What is a Compact Amplifier?
Everything here is 300mm wide or less, against the 430mm or so of a standard hi-fi chassis - narrow enough for a bookshelf, a desk or a cabinet that will not take a full-width component. This is a size class, not a circuit type, so most of these are integrated or streaming amps that also appear on those pages.
How much power do these have?
The 50 Compact Amplifiers listed here run from 10 to 150 watts RMS into 8 ohms, with a median of 58 watts. For most rooms and most speakers the median is already more than enough - doubling the watts buys about 3dB, which is a small step in loudness. Sensitivity and impedance decide more than the number on the box.
What do they cost?
Currently $90 to $3,799, with a median of $784. Prices are the current asking price we hold, not a sale price, and they change - check the retailer before deciding.
Which features should I check for?
38 of 50 have a built-in DAC, so a computer, TV or CD transport can connect digitally; 10 have a phono stage for a turntable; 26 also stream over the network.
Will one fit where a full-size amplifier will not?
That is the whole point of the class, but width is the only part of the rule. The narrowest here is 59mm, and a few are narrow yet tall enough to stand upright rather than lie flat, so check the height and the depth against your shelf before ordering. Every listing on this page shows all three.
Do I give anything up by going compact?
Mostly power. These average 64 watts into 8 ohms, against 139 watts for the wider amplifiers we list. The biggest output stages need the case volume and the heatsinking a small chassis cannot give them. For a normal room and reasonably sensitive speakers that gap rarely matters.
