Ideal for Audiophiles

These Amps & DACs are designed for discerning music lovers. If you are someone who cares about audio quality deeply, you'll want a pair of Amps & DACs like these. You can expect these Amps & DACs to present you with a refined listening experience. The audio quality exhibited by these Amps & DACs is a beautiful mix of musicality, technical brilliance and high precision. These Amps & DACs deliver a spacious and open soundstage that compares listening to music on actual speakers.

Two Way Speaker

A two-way loudspeaker has two speakers in it, each meant to present a frequency selection, usually high and low. A two-way speaker has two types of drivers which are known as a woofer and tweeter. The advantages of a two-way speaker are that it requires a simple crossover, small and compact and requires low amplification power. The performance of the music is relatively focused and balanced with low distortion. The general bookshelf speakers are two-way speakers.

Metal build

The longevity of your headphone/devices is strongly affected by its build quality, and a poorly built pair is more susceptible to breaking in a short amount of time. This is even more important for the listener who travels with their headphones/devices frequently, as wear and tear are more probable.Headphones/devices built with metal and metal components usually tend to last longer and can withstand wear and tear and potential damage. Modern processes allow all kinds of precious and durable metals to be used while making devices and offer a longer lifetime for users.

Pair with Laptop via USB

A majority of people use a laptop as the primary source device to listen to music or watch movies. Since the laptop is an essential part of the audio chain there are headphones and devices designed to work a laptop or computer system flawlessly. With the availability of USB connectivity, it becomes easier to pair various devices like an Amp, DAC or even headphones without worrying about drivers or any additional piece of software.

Volume Controls

If your Amps & DACs have volume controls, you will be able to adjust the volume level with a simple touch of a button without having to reach for your source device. Your music keeps playing without being interrupted or accidentally paused during playback. Having volume controls on Amps & DACs or at least in-line controls on the audio cable may seem unnecessary to some people, but they are, in fact, quite convenient.

In one word - POWERFUL!

This little amplifier is extremely powerful but a bit sharp/lean for my liking hence the 4-star.

We really appreciate the genuine feedback, we'll share your thoughts with the brand as well!

Best budget Amplifier

A300 is one of the best budget amplifier you can get. It is very clean and powerful class D amplifier. Class D amplifiers are not a joke anymore. You can buy 2 and use it in bridge mode as monoblocks.

It has excellent build quality. Sound quality through Bluetooth and USB is not so good compared to the RCA. Only disadvantage I see is the blue led light. They should have given option to switch off the led light. Other than that extremely happy with this product.

Hey there, nothing makes us happier than knowing you loved your purchase, hope you had a comfortable shopping experience and thank you for the great review and ratings!
