Amplificatori
The amplifier is the component that connects the source to the speakers: it receives the weak signal from a turntable, CD player, or streamer, allows you to select the input and adjust the volume, and provides the power needed to drive the speakers. In a stereo hi-fi system, it is the element that more than any other determines bass control, dynamics, and the ability to sound clear even at high volumes. Choosing a hi-fi amplifier therefore means starting with two questions: which speakers it will drive and which sources you will connect to it.
There's no single type of stereo amplifier. Solutions vary in architecture (all in one chassis or separate components) and technology (transistors or tubes). Below is an overview to help you navigate and choose the category that's right for you.
Integrated amplifier: the most popular choice
An integrated amplifier combines the preamp section (inputs, selector, volume) and the power stage in a single device. It's the most practical solution for most systems: fewer cables, less space, and a single remote control. Many recent models add a DAC with digital inputs, a phono stage for the turntable, a headphone output, or even network streaming, becoming the hub of the entire system.
- Transistor integrated amplifiers: solid state in class A, AB or D, from compact models with integrated streaming to large integrated amplifiers capable of driving demanding speakers.
- Integrated tube amplifiers: for those looking for the timbre and stage presence typical of tubes, ideal with high sensitivity speakers.
Preamplifier and power amplifier: the separate component system
By separating the two functions into separate devices, you get independent power supplies, less interference between circuits, and the freedom to upgrade one component at a time. The preamplifier handles sources and volume; the power amplifier only supplies power to the speakers, whether stereo or paired with monoblocks. This is the ideal solution for those with demanding speakers or who want to build a system that can grow over time.
- preamps: line, with phono section, with balanced XLR inputs or integrated DAC.
- Power finals: stereo and mono, solid state or tube.
If you're undecided between the two architectures, our guide to integrated, pre-amplifier, or receiver compares the advantages, limitations, and typical listener of each solution.
How to choose the right amplifier
- Speakers first: impedance and sensitivity determine how much current and power they need. An inefficient speaker or one with low impedance requires a robust amplifier; a highly sensitive one sounds good even with just a few watts.
- Listening environment: A large room and high-volume listening require more headroom than a medium-sized living room.
- Sources: Consider how many analog and digital inputs you need, whether you have a turntable (and therefore an MM or MC phono stage), and whether you want streaming already on board.
- Outlook: If you plan to upgrade your system over time, an integrated preamp or a preamp/power amp combo leaves you with more options.
