No copy of blueLino came with my Nokia Zuspielern clear (It crackled continuously, like an old record, but unfortunately unpleasant), 2 tested Home Spots had some noise, making the transition between tracks strong, low frequency 'thump', a total of 4 Sonys were all very moody when they connect (5 attempts and more, sometimes still no connection) and, even worse, the audio transfer from notebook "swallowed" the Sony regularly, the signal was delayed and was chopped.
The Harman has so far given with any of my setter (Nokia, Apple, Samsung, Acer) a nakedness. I have given him even as an output device for a Multitrackmix (24bit / 44.1kHz) in Cubase and he has not come when playing into a skid. The Sony was already the stability test by Cubase through by a second he lost several times the Sync. Hearing he had then no sound.
The Harman Kardon enjoys so fully - so it should stay!
