Some of today's mini av receiver versions are tiny adequate to hide them practically anyplace.

When choosing an amplifier, your initial consideration probably is the amp output wattage. You will will need a higher wattage if you are driving loudspeakers with a reduced sensitivity (expressed in dB/W), for driving loudspeakers in huge rooms or for outdoor loudspeakers.
However, be cautious not to overdrive your loudspeakers.
This can injury your speakers beyond repair.


But don't be overly concerned about wattage.
An amp supplying 20 to 50 Watts will give you a lot more than a lot of energy to sufficiently generate a speaker in any but the largest room.


Amp output energy is provided as Watts rms (constant) and Watts peak. The rms or continuous value tells you how a lot energy the amp can provide continuously whilst the peak electrical power figure tells the optimum wattage that the amp can provide for quick periods of time. You need to pick an amp that has sufficient rms electrical power, even though 10 to 30 Watts ought to be a lot for most applications but has adequate headroom for peaks that occur in music signals.

There are other parameters that are more important than wattage when picking an av receiver. A single important parameter is referred to as total harmonic distortion or THD in short. No amp is totally ideal and the amplified signal will consist of some error elements which will distort the signal to some degree.
THD is either expressed in % or dB.
A smaller distortion variety implies a reduced distortion of the audio signal by the amp. Audiophile amplifiers will have distortion numbers of generally much less than .05%.
Customer-quality amplifiers will have distortion figures of up to 10%.

One more specification is referred to as signal-to-audio percentage. This amount specifies how very much undesired elements this sort of as hum and tone the amp will add to the audio signal. Higher-end amplifiers will accomplish a signal-to-audio percentage of at least 100 dB although purchaser quality amplifiers will typically have a signal percentage of at least 80 dB.

The majority of today's amplifiers are structured on a engineering referred to as Course-D which presents increased strength efficiency than amplifiers centered an Course-A or Class-AB technologies.
High effectiveness indicates that small electrical power is wasted as heat which can make the amp pretty modest.
Some of today's mini amplifiers are no bigger than a deck of cards.
On the other hand, when finding a Class-D (digital) amp, be certain that the amp has reduced distortion and a higher signal-to-tone proportion.
