I've been using the ACPWorkbench to customize my audio system, and the sound quality improvement is outstanding. The software provides powerful tools that are easy to use and highly effective. Additionally, the customer support team is very responsive and helpful, quickly providing me with a new license key when I needed it. Highly recommended for anyone looking to enhance their audio experience!

I 3D-printed a case, got some nice used Yamaha speakers online, and tuned the sound with APC-Workbench. This is for my son as an Easter present. He will love it!

I have been using arylic products for some time with no problems. I recently ordered some amp’s that had a firmware issue and contacted support not knowing if my problem would be solved. Victoria answered my email very fast and came up with a solution that fixed everything. Fantastic support! It made me trust the company for future purchases. Thank you

The H50 (32V) has been in the house for almost 4 weeks, needs to be tested a bit before one can draw a conclusion.
have tried various speakers and subwoofers.
everything from 10" speakers and up to 15" sub.

but..... I landed on a setup, as the amplifier is sold as a "bookshelf"
Some old classics Mission M70.
Klipsch SW-110.
And the combo played out of the office (the office was too small), and into the kitchen/living room.

The amplifier connects easily and quickly to the network and other wireless devices.
and no ugly power on/off sound. as some of the YouTubers have reported.
I also liked that you could remove the terminal screws, so you could more easily install the speaker cables👍

The amplifier connects to Spotify without problems on Android.
and you can easily select the amplifier as playback, and it happens in seconds.
AirPlay 2 works equally well from both iPhone and iPad.

As a hifi head, I am happy that Tidal has support, since Tidal has higher sound quality.
You notice this if you compare playbacks of the same song on both Spotify and Tidal.
But I miss Youtube music support, since it also has higher sound quality than Spotify. Hopefully it will come later. Since this is in software and not hardware.

I also like that the H50 has the option to use the API for a smart home solution, but I have to try that later.
I don't need this yet,
since the amplifier has Alexa support.

It was very easy to link to Alexa, and works excellently with voice control.
Another bonus of the amplifier being Alexa supported is that it automatically came up in my smart home system Homey Pro. Since I have linked Alexa and Homey Pro.

The HDMI arc is one of the highlights of this amplifier, especially if you don't want to have more than one remote control when using it with a TV.
You just plug in the HDMI cable and the TV turns off the internal speakers and the sound comes straight to the H50. And the volume on the H50 is controlled by the TV/TV remote control.

I liked this better than the remote control that comes with the H50.
The remote control that comes with it is a bit of a letdown, because it is of the simplest kind.
But it works as intended.
But this is nothing to complain about, since remote controls are almost 2000s.
In 2025, App control is the thing, since the music player is operated wirelessly from a digital device.

The 4stream app is very easy to use, but feels a little unfamiliar.
and I have one complaint about the app, the EQ in the app.
it has a little too few notches and adjusts the sound.
so I'm considering spending $20 on ACPWorkbench Audio Effect Tool.
but it will have to wait a bit since I'm planning to change PC soon. and the license is tied to 1 specific PC.

price/content in relation to competitors.
Acrylic actually has a hidden secret there 👍

I have to pay import duty of course. but.... Acrylic was so nice to set the value at $12 !!!!!!!!
So the total price was about 23-25% lower than if I had imported from a competitor with roughly the same features.

I am so satisfied that I will buy the S50 pro
and test it against 2 old Elektokompaniet power amplifiers from the early 2000s.

Excellent product, app and service. Highly recommended 🇩🇰

I bought 2 of the up2stream 2.1 amp boards 2 acrylic cases for said amp boards and also bought an s10+ along with the DSP software package. Super simple to set up and customize via the software. The 4stream app is easy to use and really makes provisioning the devices easy. I have the amp boards powering some bookshelves in the kitchen area as well as the basement play space. The s10+ is attached to my theatre room preamp to provide access to my Spotify premium. I still want to grab a couple of the a50x50 X2 devices for the garage and living area in the house. Easy to use, easy to group areas together for multiroom audio...and no delay, amazing. Would be neat to build a boom box with one of the amazing plate amps too. So happy I came across their products. Very happy customer, I have already started marketing it to my friends for their needs. Such good products.

This is my 2nd purchase! Used the product to make my patio speakers active. Great audio quality and unmatched convenience with WiFi and Bluetooth controls with the phone.

Just what I've been looking for does exactly what its suppose to do. I love little box works great.

This is a great little streamer! I hooked it up to a small set of passive bookshelf speakers in the living room and it makes a great little sound system without taking up half the room. I also purchased the case for this and added a small set of 3mm rubber feet to the case for it to set on. It looks and sounds great! The remote control is a great addition to complete the system.

It is a good board with a quality finish. The sound quality depends largely on the speakers used. On vintage 2-way 4Ω speakers, it sounds very nice, with no hum or any other squeaks in the background.

However, without an IR remote, it is not very practical. If you want to shut down only the amplifier while keeping the internet connection active, you might run into some issues. This cannot be done without the remote, as the LED on the board remains ON if you mute the board using an external key. Additionally, if you cut the power, you have to wait about a minute for it to reconnect.

The provided schematic for external buttons and LEDs is not straightforward and can be misleading—for example, the pull-up resistor for the KEY is already on the board.

At the end of the day, I will probably buy more of these boards.

Up2cast amp review(eng) 👉:

Всем привет,плата работает отлично,очень много входов,можно раздавать аудио сигнал по Auracast на другие устройства,есть приложение,подключил три платы в режим три-ампинга,но об этом подробнее в видео 👉:

I love my 80s hifi stereo system and for years have been looking for a way to preserve the sound quality with digital audio. This device not only does that better than any competitor but it also allows me to take my stereo sound and share to speakers around the house. This truly is my favorite new part of my smart house. I know I'm going to buy a lot more of them eventually.

Plugged in and worked straight away - really handy to play and stream my digital collection through my analogue hi fi now !

I bought 2 of these Up2Stream AMP to be able to use my old good quality DCM speakers for playing music using Bluetooth. I was also impressed with the customer service. I ordered two acrylic boxed for the Upstream AMP boards and ended up ordering the wrong boxes. After contacting them and explain what happened, they immediately send me the right boxes at NO COST!
