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 .. !!!!
So far I have had 3 HD boards and 2 have failed. It is very difficult to get any feedback about what is wrong but the update process does seem suspect and one board definitely seemed to have a solder quality issue. Heating the board a few degrees with a hairdryer brought it to life.
Having some feedback about what is wrong would convince me that the issues are being worked on.
It does sound very good when it works but overall it needs some serious work by Arylic.
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
This board works brilliantly
The sabre 9038 dac chip gives a sound with excellent clarity.all the ins an out give anyone a vast option to use
This little device works perfectly with Apple music. No need to use the 4Stream App other than to connect. Fidelity of the music is great for streaming. Would highly recommend!
I wish have more ph2 cable within the package, but otherwise it’s a good product !
