Great device great sound, Then I also want to write a recession. I have realized a decades-old dream with this amplifier. It arrived well packaged. When unpacked, operate this amplifier with the Auna 501 FS WN line speakers and the Madison MAD-CD10 FM CD player. Turned on briefly waited then connected to Bluetooth which works without any problems. I've tried TV, PC and cell phone, everything works perfectly. music playback nice pleasant sound, Bass mid and treble are nicely balanced for me and no one dominates. Good language understanding even when playing sound from a television. I can't understand the annoying flashing of the Bluetooth lamp now, it only blinks when Bluetooth is switched on and no device is paired otherwise it glows permanently orange, which I don't find annoying. CD and radio playback also simply has great sound and the Bluetooth light is then off. I can't say anything about longevity now. As far as I'm concerned, I can only make a purchase recommendation and as far as the price is concerned, it is unbeatable. I haven't discovered anything negative now and I am therefore giving 5 stars and hope that this recession is helpful.
