First of all I was surprised at how small the receiver. It can be wonderfully hide at the back of the amplifier, as it is nearly as thin as a Chinchkabelstecker. Connecting wired performed. I have the tape in connection taken. Caution: Do not use the record player input (happened to me, but it sounds weird). What then is super: My amplifier has a power outlet on the back, here I was able to connect the tiny power supply of AmazonBasics Bluetooth audio receiver. It will be automatically switched to the amplifier and. Super matter (but which is attributable to my great amplifier).
The connection with my Tablet PC managed immediately. The small button on the back press (lamp flickers now faster) Bluetooth on and the receiver has been shown with a small headphone icon. Great that you can still go on the Internet if the connection is established.
Then I started the Amazon music player. Volume to 50%. When amplifier turned up to the first quarter. The music was then a little quiet. But one still has the opportunity to settle to 100%, or more turn up the volume control on the amplifier. The sound quality is good. No noise, crackling or any disconnections (at a distance of 8 meters between the kitchen and living room with a partition).
I made then a comparison with the CD player (Kenwood with fiber optic cable) and put the same music on a CD to have a direct comparison. Then I clicked between both inputs to and fro. What can I say, I could not detect any significant differences. If anything, that can perhaps Hifispezialist with instruments. Mir is nothing noticed neither classical, pop or rock music.
Tablet PCs because of the Bluetooth transmission can not be activated several effects. Equalizer settings but already taken. Here I leave everything but on neutral and place it rather on the amplifier.
Conclusion: Of course one could connect his Tablet PC directly to the cable and then transfer the music. But then I can not comfortably sit on the sofa and surf the Internet. Everything continues without cable. I think that part great. Works flawlessly with good sound quality and tiny size hardware. I give it 5 stars.
