knotless sound

Am pleasantly surprised by the good sound of Hama preamplifier. In battery mode, it works flawlessly. A connection via power supply is however not recommended, as otherwise interfering hum noise spoils the music enjoyment.
Another plus is the on-off switch and the earthing. For this, the small footprint is due to the compact design.
Value for money and speed of delivery as always unrivaled play Amazon.
The only downside: would have liked at least one (cheap) battery included.
Nevertheless, a clear buy !!
