Amplifiers, the heart of your system.

At the start of our great cold season, as we return to our inner routines, I'll be revisiting with you the various components for your everyday entertainment.

First, let's take a look at the heart of your audio system: music first, and in a second article, its cinema version. I refer to the audio amplifier.

Role of the stereo amplifier

Role of the stereo amplifier |

Essentially, music follows a three-stage path. First, it appears via a source that takes a variety of forms. Whether digital via a network player, analog via radio waves or a turntable, sound materializes as a weak electrical signal. To make this signal audible, the loudspeakers have the task of vibrating the ambient air so that our ears perceive it. As the signal is very weak, an amplifier must be inserted into the distribution chain.

There are many different types of amplifiers available in a wide range of prices. It's important to establish our needs and expectations in order to guide our choices. As a preamble to a forthcoming article, we'll make a link with the other pillar of sound reproduction: the loudspeaker. Both elements must be chosen with each other in mind. Next, I'll introduce you to the Paradigm range of loudspeakers.

The 4 types of stereo amplifier

Power amplifier

This type of device is sought after by the serious audiophile looking for power and precision. This type of amplifier only powers the speakers, and requires a preamplifier to select sources and adjust volume.

Integrated amplifier

Integrated amplifier |

An integrated amplifier is a device that lets you select the input source, adjust volume and tone. As opposed to a power amplifier, which does not allow selection or control, and requires the addition of a preamplifier. It's perfectly suited to people who want to take things step by step, and also to those who modify the various components of their audio chain over time.

Radio and/or network receiver

Radio and/or network receiver |

Here, we're talking about an "all-in-one", because, as well as amplifying sound to the desired listening levels, it will enable you to listen to sources such as good old FM for radio receivers, or now, web radio in its Network version. What's more, network receivers will incorporate a DAC or "digital analog decoder" for listening to the famous FLAC and DSD files available for download on the market. This kind of product is becoming the norm for most audiophiles looking for a valid, easy-to-configure solution.

All-in-one amplifier/player (the future) |

The compact network amplifier/player is a relative newcomer. This kind of device involves a built-in amplifier to enable the attachment of various peripherals (sometimes even turntables), but also incorporates a full suite of functionalities adapted to the digital world offered by webcasting. Calling on new design possibilities, it will be very compact and user-friendly, incorporating a large display and an application similar to that found with network players. It's the ultimate in fidelity and performance. Both high-end and entry-level versions are available.

What you need to know before investing...

Without going into too much detail, we should aim for a low distortion rate of less than 0.05% to ensure good listening realism. The second point is power, which for ambient listening should be at least 50 watts per left and right channel, i.e. 100 watts in total. For more dynamic listening, 200 watts or more are required.

Note that the more power you have at your disposal, the more you'll be able to avoid distortion in your listening, as the amplifier won't "force". It's a well-known fact that sound quality deteriorates rapidly when capacity is exceeded. What's more, an amplifier that isn't powerful enough for your needs could damage your speakers...

Many people believe that speakers need to be more powerful to stand up to abuse, but this is a mistake, because it's quite the opposite. An amp that's too powerful will provide a cleaner current that will cause the speakers to rattle when pushed a little too hard, so you'll hear it and turn down the volume. Conversely, an amplifier that isn't powerful enough by exceeding its capacity will supply a continuous current that will melt the speaker coils. You won't hear the extent of the damage, because direct current generates no sound... except when it's too late...

Entry-level models

For those who want to experience the richer listening experience of specialized sound equipment. An experience far beyond car or portable radios of any kind.

Not so long ago, there wasn't much of value in this category, but manufacturers have made the right decision to offer accomplished products at more than reasonable prices. The rational being to bring more fans into the audiophile family.
