A general answer to this question and I will not presume. In the ranks of the three hearing test loaded stainless powered speakers but I can answer the question with « Yes ». In direct switch between the three noble stereo pair, the difference could be heard loud and clear, almost as if someone pull on the way from the Bose B & W to Harman Kardon, a set of curtains.
The B & W MM-1 to outdo the other hand, with a little more rounded bass and softer overall sound. Just as with Bose also its strength clearly lies in the sound of a computer user who placed the boxes next to his screen. Your USB port eliminates the user from the – not always designed to Hi-Fi – sound card in the PC independently.
The hit but the Gla-55 from Harman Kardon. Whether you like it or not the crystal design: The sound that produce extremely eye-catching plastic form, is simply good – if they are set up correctly. The price that the manufacturer requires it, but it has to be. With 799 euros, the transparent boxes are in the price list – but this award requires fortunately hardly a dealer really, they are usually offered at lower rates.Nevertheless, they are still pretty expensive – but you can hear that.
