Solid processed but overcast sound

The "Advance Acoustic WTX 1000" is solid and will send in a supplied black metal housing, which features an uncluttered front. In addition, the device features that are missing from many other Bluetooth receivers, such as an on / off button, an analog output (RCA type-pair) and digital interfaces has. So standing next to a TOSLINK optical socket and a coaxial S / PDIFAusgang at your disposal, so you connect the "Advance Acoustic" at respective interfaces as an AV receiver, but also on an additional D / A converter and thus directly from its qualities can benefit. Whether one chooses the analog or digital interfaces, is determined using a selector switch on the back of the device.
Pairing with a Bluetooth device works perfectly, the reception at the house between 8 and 10 meters. And yet there is a great disappointment in this device: The output power is very small, so you have to turn up the volume twice as high as for example the "Philips AEA2500 / 12 Bluetooth stereo adapter". The sound of the "Advance Acoustic" works by dull and overcast; lacks transparency and spaciousness regardless of whether you connect the device to an analog or digital stereo. The promised CD quality does not want to adjust to my devices (iPad mini at "Naim Uniti 2" or headphone amplifier of Music Hall with Beyerdynamics T1). In addition, the cable of the power supply with just under 1 meter length is absurd short.
