"The Connector2 can be integrated into networks with or without a cable. The cable connection is very simple. One simply inserts the appropriate network cable into the corresponding interface on the device and the Connector will be connected to the home network. [...]
If the Connector is connected to the Wi-Fi, it must be added as a ‘new room.’ For the setup, an Ethernet cable must be attached to the Connector, following which the Raumfeld App can be added. The router password must also be entered. The automated configuration for the Wi-Fi will follow, after which the LAN cable can be disconnected and the Connector2 will be wirelessly connected to the network.”
"The Connector plays MP3, WMA, WAV, AAC, FLAC, OGG and Apple Lossless. A 192 kHz sampling rate is supported which makes the Connector2 compatible with high-resolution audio files. [...] The Connector creates an impressive-sounding playback with 192 kHz FLAC pieces such as Wolfgang Amadeus Mozart’s violin concert (SL Recording) in D minor. The details, clarity, and dimensionality are highly pronounced. The violins as the primary carriers of the song sound brilliant without having too sharp a tone. Even the complex piece ‘La Mer’ by Claude Debussy was captured in a very multifaceted way, including the many small dynamic differences which were accurately produced. The 96 kHz FLAC piece ‘Stop This World’ by Diana Krall has a lively, emphatic quality with a taut bass that is well differentiated in the listening room. Dianas’ voice has a smokey undertone, giving it a charismatic quality.
Depending on how good the D/A converter in one’s amplifier/receiver is, it’s possible to access the digital connection if this is available. In any case, we recommend a listening test before deciding on an analog or digital connection. Especially with older or inexpensive amplifiers/receivers, the use of the Connector’s very good D/A converter can be the better option. Even when bitstreams are transmitted from Internet radio platforms (TuneIn), the Connector ensures a lively, dimensionally rich sound with a high degree of clarity. The reliability of the transmission is very high. It doesn’t matter whether it’s connected to a LAN or Wi-Fi – interruptions are almost never discerned. This is true for the reproduction of Internet music streams as well as sound files from PCs or servers.”Conclusion
"All told, Teufel offers a highly polished solution that can make hifi systems and older surround receivers fit for the era of modern media. With the exception of Spotify, all relevant music services are integrated and it’s easy to add music resources from PCs, servers, and USB storage devices. Playlists are quickly set up and can then be easily accessed. A free app enables simple handling so that even less experienced users can quickly and easily figure it out. The Connector2 can be connected to the network either with a cable or wirelessly. No Wi-Fi antenna intrudes upon the compact enclosure. The sound that the very compact and therefore easily accommodated Connector makes available is excellent and corresponds with Raumfeld’s claim to offer first-class streaming quality.
Flexible to use and strong on sound – the ultra compact Connector2 delivers on all counts." Translated from the original German.
