Buying Guide For Best Stereo Preamp Under 500

These are the following factors that you need to look for when you consider buying an amplifier.

The right connection points

The right number of connection points are very necessary to allow you to connect the various existing units to the amplifier. These include analogue inputs like RCA audio inputs and an RCA phono input. Multiple digital audio inputs like optical, coaxial, USB and Ethernet connectivity is also necessary to make the unit user-friendly. Some of the systems also come with a built-in digital-to-analogue converter for additional convenience.

Matching with the speaker

To match the amplifier with the speaker, it is often recommended to select a model which has twice the power of that of the rated amount in the speaker. This excess amount of power will allow enough allowance for the speaker to deliver a clean and undistorted sound output. This is also important if you choose to play music which has a large dynamic range. In case you are working in a sensitive studio environment, you should select an amplifier which is three to four times more than the speaker’s program power rating.

The right impedance

Most amplifiers are designed with 4, 8 or 16 ohms of resistance and the optimum performance is obtained when the total ohm load of the loudspeakers match with the amplifier. The power delivery to the loudspeakers will depend on the value of the impedance and overloading may damage the system. It is also possible to connect multiple speakers with one amplifier provided the wiring is done correctly and the total impedance does not fall below the specified output impedance of the amplifier.

The right placement

The surface or the position where you put the amplifier can make a world of difference to the overall sound quality. Since the power loading can heat the unit up, makes sure that you give it enough breathing space and use the right type of rack. The type of surface depending on glass or wood can affect the sound delivery. While glass makes it slightly upbeat, wound provides a more warm tone.

Wi-Fi connectivity

Many amplifiers come with built-in Wi-Fi and allow you to connect the unit to your home’s wireless network. They also come with Bluetooth that allows you to connect with any external device like a Smartphone. Some devices also come with Apple Airplay that offers seamless connectivity with all Apple devices.
