Very good sound, convincing solution

Looking for a Bluetooth adapter solution I chose for the adapter from Harman, because these manufacturers in the hi-fi and home theater systems at home and for many decades on the market is active and is therefore likely to have relevant experience. Connected and heard about the following system / environment: Trigon Energy with Dynaudio floorstanding speakers, CD Trigon Recall 2, Cable: Burmester lila with adapter, Bluetooth transmission via Acer A700 Tablet on AVM routers 7490 (Telekom provides 16.000er line), heard about Spotify free.
Sound: Since conversion to AVM routers without misfires, absolutely trouble free, Spotify provides 192 kb / sec average MP3 level, compared with Rosanne Cash The River & The thread, CD against Streaming: The sound of the Harman is about on par with our SAT digital radio, the sound from CD something "distant", softer, less space. Treble / Bass, however, to - for this transmission - absolutely satisfactory level. I think that since under aural aspects technically (source, transmission path) is not much longer rauszuholen. Important to me was the trouble-free operation and here the Harman may, under the conditions described points. If anyone here have problems, which is probably not the adapter. We had a telecom router (700), there were ever problems with the wireless transmission. Since the conversion to AVM, there are no more problems. Therefore: Highly recommended as good interference-free sound. The housing falls by the way very compact from (slightly larger than a matchbox). Thickness RCA (adapter) plug incidentally do not fit into the 3.5 mm connector, since the case here is in the way, perhaps the only downside.
