A preamp, also known as a preamplifier, is an electronic audio preamplifier that converts a weak electrical audio signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and an active speaker.
Without this, the final audio signal would be noisy or distorted.
The preamp is to amplify the audio signal to the input range acceptable to the power amp. It has the characteristics of selecting the required audio source signal and amplifying it to the rated level and beautifying the sound.
The role of the preamp:
Select the required audio source signal and send it to the rear stage, and at the same time close other audio source channels, and amplify the audio source signal to the rated level to achieve high-fidelity sound quality.
The difference between an audio power amplifier and a preamplifier
The preamp is to amplify the audio signal to the input range that the power amplifier can accept, and the audio power amplifier is to generate the maximum power output to drive a certain load amplifier under the specified distortion rate conditions.
The preamp is an audio processing device before the input audio power amplifier; the amp controls the power of the sound, and the preamplifier controls the audio range.

Airplay не работает! Приложение тоже минус. Покупал для Яндекс музыки через airplay, но ошибся. После нескольких дней понял, что Китай пока не может… кому Airplay не нужен то наверное сойдет.
Easy setup as long as you read instructions correctly.
I bought two Arylic S50 Pro+ streamers --one off Amazon and the second straight from Arylic. Although I like the functionality after connecting through the quirky 4stream app, the one I bought straight from Arylic suffers from constant music losses. It is annoying and frustrating as I don't have any losses or skipping using any of my other streaming services on any other equipment. I bought the second for my study as the first one seemed to function OK. To be fair, I wrote to the company and will give them a week to see what happens. Am considering returning both of them as I had fewer complications and annoyances just streaming from my pc or Bluetooth from my phone.
Yes, I'm quite satisfied with overall quality. First start, was straightforward, easy to connect and configure, to Wi-Fi. The unit is small and compact, but is easy to connet the cables, from behind.
Sound quality is excellent!
Only note is, missing of more granular volume control. Volume control is with step of 5, which makes big increase and decrease of the volume.

I have two S50Pro+ and a S10 streamer. Deezer is no longer accessible on all of them since April 12, 2023. So think twice if you are making a purchase.
For a few days, you can't access Deezer on 4stream and Wiim Home either. So I can't use it right now. I hope someone has a solution. So far, everyone has only been sent to someone else.
