Officially APP 4Stream for Arylic Wireless Multiroom Audio System

Nice product but it's not quite finished yet.
I use this dac in combination with Apple music and Apple TV.
While starting a music track, I regularly hear that the track is briefly restarted for the 2nd time. This is very short. I tested this over WiFi as well as over a wired one.
Another problem I regularly experience is that the sound during a feature film sometimes just stops for 30 seconds for no apparent reason. Then the sound will simply play again. This also happens over WiFi as well as with a wired connection.
My internet connection has been tested and is in excellent condition.
What works well is the combination with Up2Stream Amp Sub - Multiroom Wireless Subwoofer Amplifier Board the synchronization works really well. What I think could be improved is the volume control. It would be nice if the ratio that can be set via the app between the different nodes in terms of sound pressure increases evenly. Now it is the case that when sending open everything is opened to the maximum and the ratio you set is lost.
Trebble and Bas do nothing in the app my firmware version: 4.6.414645.35
What could be a nice addition is that you can see which audio resolution is being played. (I also have the display)
The sound quality is really good, the ease of use is also great in my opinion, definitely recommended.
Hopefully everyone can benefit from this information

I'm an happy user of an Arylic S50 Pro that I used to play Hi-Res contents from Amazon Music Unlimited with Android smartphones.

Used in BT mode 'cause I'ld use original Amazon App and above all , Poweramp Equalizer that allowed me a perfect frequencies setup.

Attracted by the new Up2Steam HD DAC , which promised better sound performance with a new ESS DAC and moreover "No Downsampling".. 1: 1 reproduction.

After some time I broke the delay and took it, completed with its beautiful case and replaced the S50 Pro .

Wooahhww ... !!! never purchase has proved more appropriate ...!

Used in Wi-Fi mode (here the difference with BT is noticeable), the effect does not resemble a Streamer replacement. Much more .. as if I had changed the whole HI-FI composition from good but basic brands to HI-END McKintosh compositions or similar ... !!!

My old Pioneer 6500 Mk.II Amp connected to a basic EQ Beringher FQB 800 and to KEF Q55 Mk.II standfloor speakers, with new Up2Stream HD DAC are able to give "Best of Themselves" with a Quality never heard before, turning into a New Life.

With Volume knob at 1 1/2 my Old Hi-Fi reproduces a real "Wall of Sound". Impressive power and clarity of sound, perfect channel separation, accurate balancing of output for different Instruments and Voices, details and clarity never heard before.

Creation of a Powerful and Detailed Soundstage with Voices & Instruments emissions perfectly distinguishable & integrated with each others .. !!!

Well .. listen Freddy Mercury singing "Love of my Life" closing my eyes... gives the impression of having "now" Queen in Concert directly in my living room .. !!!

Wouwhh .. Really Awesome ... !!!

My sincere congratulations to Fran who studied and implemented the creation of this "Jewel" and to Joy who, as always, took care of the order & delivery phases in an impeccable way.

If someone want to play his Old Hi-Fi with an unsuspected quality, never heard before...purchase of Up2Stream HD DAC Card is a real blessing, the most well-spent money with truly effective and detectable effects at first listening of any Know Song.

Only a prayer to Fran..add the direct access to Amazon Music App, as is for Spotify and Tidal yet.

Up2Stream HD DAC .... try it and .. you won't be able to do without it anymore . A True (Good) Addiction .. !!!!


I'm installing the U2SP V3 into my late 70's Nikko NR-1015 stereo receiver for some seamless streaming. In testing I've been surprised by a few things. The Arylic board has a fully sufficient preamp output so that it matches the receivers FM section output. I was expecting it to modulate poorly like many auxiliary inputs into vintage receivers. Better still the streaming quality is excellent. Even bluetooth is smooth and it sounds far better than I expected. Again great modulation and plenty of headroom for tonal adjustments. There are also many great options for free streaming wifi radio and of course Spotify, Napster etc. It connects well with the provided antennas and the setup was child's play. This device has solidly exceeded my expectations in terms of sound quality and would absolutely recommend it to anyone who likes things that work! Provided image is a mockup of the finished installation.

S50Pro + is a good complement to my retro amplifier.
I use it mainly for Tidal, TuneIn streaming and Bluetooth connection to the projector.
The audio quality is fine, easy to connect to the network.
The display has clear symbols of the source, so even from a distance it is easy to recognize which source we are operating on.
Among the issues that could be improved are: replacing the infrared in the remote control, to bluetooth, adding a more advanced configuration for managing bluetooth devices, adding the option to turn off the beeps when pressing buttons on the remote control.
I recommend the device as a solution with great quality for the price.

This little gadget is a real gem, even Spotify sounds excellent!

I setup 2 zones with this streamer ($79) along with Lepy LP-2020A amp ($29). I can play individual zones from different sources, or all zones same music, means source from zone 1 can play in zone 2. You need an amp. Sound is perfect with amp. You can play various internet stream, radios, and blootooth. Works great. Buying one more for another zone. iPhone app can control the device in the network. Each zone has different names in the Bluetooth pairing, so you can choose the zone in your phone to connect to that zone. App has options to play same music in different zone.

My settled upon and preferred streaming method is Airplay. I went through Play-Fi, Chromecast Audio and Sonos. The ability to stream my personal library via Plex is an absolute must in order to stream to my speakers of choice. Options are limited to the Bluesound Node 2i which is quite pricy and other brands even pricier.

I have several rooms so the cost was prohibitive beyond a couple of Node 2i units. What I've been hoping for is a reasonably priced Airplay 2 streamer to become available. Arylic has come through with the Upstream HD DAC. If you can get it at a discount price it makes the investment into multiple DACs very attractive. I have one now with two more on the way. With the IR remote you have transport controls for volume/play pause/previous and next. I wish the controls were on the board as there is slight latency with the remote but it's worth as it doesn't cost and arm and a leg for multiple Airplay 2 devices.

I love the amp. I love how straight forward it is. Not over complicated. The app is great obviously can use improvement. I own and audio and visual company. And Ie worked with Sonos amps, Amazon amps, and denon heos amps. Trust me this amp is great.

This works great with my 4 ceiling speakers. very easy setup and enough power for rich audio. i contacted them before making the order and an agent was kind enough to explain everything related to this device, I never thought that a small machine can do all that this product does. it was also delivered very fast. very pleased with my purchase and i will buy more amplifiers for each room.

Build a pair of active desktop speakers with it. Super easy to build with, cable routing was a bit snug on the plate amp. The L output ran across the power supply transformator which is not optimal, but no real issues there while listening. The amp has some noise, which is gone once connected to a source. ACP Workbench is a powerful tool to tune with and gets great results. Did have rare lags from the software while programming and listening via USB, which reconnecting the device solved.
Overall sound is great. Bass extension and power is plenty for the speaker i used it with (4" Widebands). Treble and imaging is pleasent too. Looking forward to use this little boy more frequently and try it on some bigger chassis in a two way system.

DISCLAIMER:This review is comprised mostly of opinions, which I have formed after spending two plus months listening to this product on a daily basis in both near- (desktop) and far-field (living room) configurations. EQUIPMENT: speakers: KEF LS50 Meta KEF Q10 Sony SA-CS9 (sub) streamers: Arylic A50+ Apple TV 4K (HDMI TV optical to A50+) MacBook Pro 15 inch, 2018 (headphone jack A50+ via included RCA to 3.5mm cable) iPhone 12 (via bluetooth)DESIGN / FORM FACTOR:Look at the first picture in this review. Can you spot the integrated amp?? No, I not talking about the Sony receiver. Look closely and youl spot the A50+ in the right-middle shelf of my console, sandwiched between an Apple TV and a copy of the card game runk Stoned or Stupid The Arylic A50+ blends seamlessly into its surroundings due to its minimalist design (consisting of a sleek aluminum housing and a glossy black front plate) along with its absolutely diminutive size. I do not understand how this thing is able to pack a 50 watt/channel punch, a capable internet streamer and phenomenal sound quality into such a tiny package.See the following pictures for a better sense of just how small Arylic designed this amp. It worth noting that this product has not ONCE become hot to the touch, despite its size. It is also worth noting that the A50+ is significantly smaller than competitors such as the Bluesound POWERNODE 2i ($949) and the NAIM Uniti Atom (~$3300) while packing a virtually identical set of features. Beyond that, Andrew Robinson, one of my favorite HIFI product reviewers and a longtime proponent of the POWERNODE expresses that he actually prefers the sound of the Arylic to it, despite the 750 dollar price gap but more on the Arylic sound later in this review.USABILITY / REMOTE:The A50+ provides a straightforward and intuitive user experience. Although I have spent very little time with the 4STREAM app and therefore cannot comment on its functionality, the included remote is excellent, with volume controls, source controls, media playback controls, and even buttons for on-the-fly EQ adjustments. Airplay and Bluetooth have been working without flaw since purchase OUND:Bass:HUGE improvement over my outgoing amp (Sony STR-DN1020 7.2.2 ch Receiver). I using a Sony SA-CS9 sub in combination with my LS50 Metas. I know, I know, it may be sacrilege to pair such nice loudspeakers with a truly budget sub like the Sony, but let me say, the Arylic has convinced me otherwise. With my old amp, bass came through as muddy and bloated, and the A50+ has completely removed these undesirable qualities from my sub performance. On top of that, bass comes through as punchy, precisely timed, and probably as textured as an under-$200 subwoofer is able to produce. Remove the subwoofer, and the story is no different. The Arylic squeezed more oomph out of my Metas than I believed they could produce, especially when I press the D-BASS button, which dramatically increases low end weight.Mids:The A50+ faithfully portrays vocals and mid-range instrumental frequencies with attention paid to fine details and without sounding muffled by its excellent bass and treble reproduction. Vocals are handled with delicacy rather than being shoved in the listener face, which adds to the sense of refinement that is apparent in this amp sound.Treble:The Arylic is a high frequency MACHINE. Even uber-high pitched frequencies, such as the barely-audible triangle played throughout Steely Dan Aja, shimmer with the help of the A50+. Despite this, the Arylic never sounds fatiguing or piercing, even after extended listening. Very smooth performance across the board, especially when considering the Arylic all-digital amplification topology.Power:My LS50 Metas are fairly low sensitivity speakers. This means that they require more power than a higher sensitivity speaker to be driven to the same volume. With that said, I have never once hit maximum volume with the A50+ (and I like to BLAST my music, especially with my living room setup).Clarity:The Arylic A50+ is a musical scalpel. There isn too much more I can say about it from this regardIt is highly intelligible and renders music with precision without sounding grainy or piercing.oundstage:Personally, I believe that the Arylic imaging capabilities are its most impressive feature. Set up in my living room, the Arylic, along with my Metas, created what a friend aptly described as room full of sound.The Arylic has the chops to build a 3 dimensional sound field around its listener, with depth and height just as well defined as soundstage width. Speaking of width, the soundstage of A50+ extends well beyond the speakers rather than solely existing in between the two, which tends to give songs a ive?feeling, as if you are right there with the artist during a performance. Things then improved dramatically in my near-field desktop listening setup, as near-field situations can avoid much of the coloration from sound bouncing around your room found...

Have puchased and installed a few of this network amplifier and been very happy with the build and sound quality.
And the best thing is their app is updated for better user experience.

I have been using Arylic products for 9 months. I was looking for a Sonos alternative. While there are many different brands sold on Amazon that are similar to Sonos. Arylic is by far the most feature packed and well built on the market. Arylic also has very good customer service. Any questions that I have and they are quick to reply.

Top seller Fast Response good true and fast delivery.

Fantastic Music streamer /preamp that is worth every penny. I was lucky enough to grab this limited version Spro + model. Highly recommended.
