Power enough, but ...

The performance of this little Amplifiers even sufficient for standing speakers. Even sound can not be faulted on the device.
There are only three points, I do not like:
1.
The external power supply is almost bigger than the device and looks pretty ugly. If you can stow it invisible, but no problem.

. 2
The Amplifier is hot; and does it really hot so you his hand as no longer want to put it permanently. This happens after
20 minutes at normal room volume. As it is only after longer full steam phases, I would not know.

. 3
Once the part is supplied with power (with or without signal cable to it) rushes the Entstufe audible through the speakers connected respectively. If you are staying far enough away from the boxing goes. But in 1 to 2 meters distance which is very unattractive.

Unfortunately, the built-in headphone amplifier is a pure gimmick. The sounds completely verhanden (rolloff). Not the point.

As an additional power amplifier for a surround sound system or similar purposes (passive subwoofer) of the SA-160 is well suited for use. For finer tasks in a hi-fi system or PC rather less.
