The 5 star I do not forgive, because the LED on the device much too bright and some are played back slightly distorted (with very high output levels). But these are really just individual cases. In addition, this converter comes naturally sounding not at quality HiFi converter as of Musical Fidelity or Cambridge Audio zoom. However, the cost also at least five times or more.
The dealer Car HiFi Corunna I can also recommend as suppliers. Very fast and problem-free settlement.
