recommended if the description is studied in detail

The amplifier also came with me to a British type G plug. I have retained and for a "1aTTack switching power supply stabilized (300 mAh)" ordered.
I also needed a connecting cable and ordered a "Hama Cable 3.5mm to 3.5mm jack 1.5m".
6.3mm jack adapter I had - five of them are in four connected headphones needed.
The quality I can not judge. The amplifier is used on a laptop at the same time of two users to listen to audio through headphones, without disturbing the environment. A noise I have not found.

Update: In August 2012, I ordered a second amplifier. This came with the appropriate power plug for Austria. For this I ordered an inline jack PREMIUM Audio Cable 2m InLine premium quality 3.5mm M / M 2m stereo gold-plated contacts Double shielded because the Hama cable is not as good shielded, it rushed at times terribly. With the in-line cable is heard no noise.
