The FiiO K3 (formerly known as the E30) is the successor to the Olympus 2 E10k, is probably the best-known product from the Asian brand. The new DAC with amplifier is based on the Q1 Mark II model but is intended for desktop use. The new, smaller DAC/AMP is powered by USB Type-C, can play DSD files, operates in two USB modes, powers balanced headphones, and can act as a digital or analog converter.

The company seldom releases such products, usually favoring DACs and portable players. However, they have always had a line of small desktop units: the K3, E10, and E10K. The new model combines a traditionally compact size with a range of inputs and outputs (including 2.5 balanced audio). Things look good so far, but will this affordable USB Type-C desktop amplifier deliver on its promise?

Whether we like it or not, we are entering a new era where many audiophiles prefer streaming music to traditional physical media. The Marantz PM7000N integrated amplifier is Marantz’s first stereo hi-fi product to support HEOS multi-room streaming integration, allowing users to enjoy music from multiple services without purchasing a dedicated audio streamer.​

With the dedicated HEOS app, users can stream audio directly from popular services such as TuneIn, Pandora, Spotify, SiriusXM, Amazon Prime Music, and TIDAL. For example, you may not have fully switched to streaming yet, or you have downloaded a large library of audio files. In that case, you can still use the NIC for UPnP audio, so you can stream files to your computer or NAS while the amp is still connected to your home network. The NIC also offers new features such as voice control with Josh.ai, Amazon Alexa, Apple Siri, and Google Assistant.

Today’s hi-fi market offers a broad range of audio equipment for those who want to listen to music in its best quality. These include all-in-one systems with Internet access, wireless speakers, portable players with headphones, and computer digital converters with desktop speakers. However, many audio enthusiasts prefer to use older, stand-alone types of audio circuits, as they can create their own sound instead of buying a standard product.

To cater to such a market, Pioneer treats its users with some exciting audio products. Among them is the A-40AE integrated amplifier. While the code name might raise some hopes, it has not come the time to remake the iconic A400X model. The A-40AE is simply another integrated amplifier belonging to the growing two-channel line-up.

One of the first products that helped Fiio gain worldwide popularity was the E5, a small headphone amplifier. This small, inexpensive device dramatically improved the sound quality of the devices at the time and allowed you to get more out of your favorite headphones. Several years later, a new successor appeared, the FiiO A1.

The FiiO A1 is a small headphone amplifier, a device enclosed in a slim aluminum case with a built-in battery. The case features a sandblasted finish and a removable transparent clip on the back, which can be used to hang the device on your clothes. Apart from these factors, the biggest selling point of this product is, of course, its low price; the FiiO A1 is a cheap amplifier that costs around $25 to $30, which is comparable to the price of budget headphones.

Prior to the PHA-3, Sony had long focused on the consumer segment. Still, as consumers confidently turned to more advanced audio products, Sony decided to move upmarket, which encouraged the production of a high-end portable headphone amplifier.

The goal of the PHA-3 was to create a reliable amplifier for the MDR-Z7 and meet consumer demand for more professional audio equipment. Of course, $700 headphones are unlikely to work at full volume on a smartphone or standard player, and the PHA-3 is an excellent choice. It’s powerful and versatile and can be connected to virtually any device. Whether it’s a computer, an external digital music source via an optical connection, or an Android or iOS device, the PHA-3 can act as a DAC. There’s also a line input, so the PHA-3 can serve as a DAC/AMP (though it’s not the most powerful).

For advanced users, the PHA-3 is capable of handling high-resolution recordings at 384kHz/32bit (the current maximum) and DSD. Another interesting feature of the PHA-3 is that it can be used with balanced headphones, with two channels connected separately. It is not surprising that such a device is not compact and inexpensive. Its large size and weight are justified by its whopping $1,000 price tag, but is it really worth it?
