Description
What the Arylic B50 Is
The Arylic B50 is a compact stereo amplifier rated at 50 watts, built around Bluetooth streaming with aptX HD support and an HDMI ARC input. It belongs to a category that has grown quickly in recent years: the small integrated amplifier designed to drive a pair of passive bookshelf speakers from a phone or a television, replacing a full size receiver in a room where one would not fit.
The combination of features is what makes it interesting. Plenty of small Bluetooth amplifiers exist, but most connect only over Bluetooth and an analog input. Adding HDMI ARC changes the use case entirely, because it allows a television to send audio directly to the amplifier and allows the television remote to control the volume. That turns a pair of bookshelf speakers into a television sound system without a sound bar. Buyers comparing desktop amplification for headphones rather than speakers should look at the FiiO K11 and the FiiO K9 Pro, which serve a different purpose within the same amplifiers category.
Connections and What They Enable
Four input routes are described in the product information: HDMI ARC, Bluetooth, RCA and optical. Each covers a different source. HDMI ARC handles a television with remote volume control. Optical handles older televisions, games consoles and disc players that have a digital output but no ARC. RCA handles analog sources such as a CD player or a turntable with a built in phono stage. Bluetooth handles phones and tablets.
The Bluetooth implementation is specified as supporting aptX HD, which is the detail worth focusing on. Standard Bluetooth uses SBC, a low bitrate codec that audibly degrades music. aptX HD transmits considerably more data and is supported by most Android phones, though not by iPhones, which fall back to AAC. For an amplifier being used as the main music source in a room, codec support is one of the few specifications that changes what is actually heard. Owners connecting speakers should look at the bookshelf speakers category, including options such as the Klipsch R-50M.
Control and Placement
App control is provided for playback and sound settings, which is standard for this category and is where equalization, input selection and any multi room configuration would live. Arylic builds a range of streaming and amplifier modules, and app based control is central to how those products are used. The listing does not name the app or describe its features in any detail.
Physically the unit is small, with a listed package size of 9.17 by 8.27 by 5.04 inches, which implies a chassis considerably smaller than that once packaging is accounted for. A compact amplifier can sit on a shelf beside a television or under a monitor, which is the whole point: it occupies the space a sound bar would take without dictating the speakers. The listing dates the product to November 2024 and ranks it 173rd in audio component amplifiers.
Highlights
- 50 watt stereo amplification in a compact enclosure.
- HDMI ARC input, uncommon on small amplifiers, allowing television remote volume control.
- aptX HD Bluetooth for higher bitrate wireless streaming.
- Optical input for televisions and consoles without ARC.
- RCA analog input for CD players and turntables with a phono stage.
- App based control of playback and sound settings.
- Small enough to sit beside a television or on a desk.
- Four separate input routes covering television, digital, analog and wireless sources.
- Drives ordinary passive speakers, so the speakers can be chosen independently.
Things To Consider
This listing carries no manufacturer description, no feature bullets and no specification table beyond packaging details. Everything above comes from the product title and the short description, and there is no documented figure for output impedance, distortion, the conditions under which the 50 watt rating was measured, the Bluetooth version, the supported sample rates, or what is included in the box. For an amplifier, the measurement conditions behind a power rating are the difference between a meaningful specification and a marketing number, and they are absent here.
One listed figure is clearly wrong. The item weight is given as 7 ounces, roughly 200 grams, which is not a plausible weight for an amplifier with a power supply and heatsinking, even a Class D design. That should be disregarded. The manufacturer is also listed as Rakoit Technology of Shenzhen rather than Arylic, which is the brand on the product. That is not necessarily a problem, since brands frequently use contract manufacturers, but a buyer should know which entity handles warranty claims before ordering, particularly on a product first listed in November 2024 with a limited review history behind it.
On capability, a 50 watt amplifier of this size will drive efficient bookshelf speakers in a small or medium room and will struggle with inefficient speakers or a large space. There is no phono stage, so a turntable needs its own preamplifier. There is no headphone output mentioned and no mention of a subwoofer output, which limits how the system can be expanded. And aptX HD only benefits Android users, since iPhones do not support it. Buyers who want a conventional receiver with more inputs and room correction should look at the receivers category instead.
Who It Suits
The B50 suits someone who wants a pair of real speakers rather than a sound bar in a living room, bedroom or study, and who wants a television, a phone and possibly a turntable feeding the same amplifier from a box that takes up almost no space. The HDMI ARC input is the feature that makes that work in practice, and it is rare enough at this size to be the main reason to choose this over a simpler Bluetooth amplifier.
It is the wrong purchase for a large room, for inefficient speakers, for anyone who needs published distortion and impedance figures, and for anyone building a surround system. Those buyers should look at a full receiver, and anyone who mainly needs a headphone amplifier rather than a speaker amplifier should compare the smaller FiiO KA13.
