And even if it didn&#39;t improve the sound, i could use the same volume level on B&amp;O amp for the internal sources as well as for the auxes - end of rollercoasting with volume up and down! ;)<br /></p><p>Anyone tried these with B&amp;O systems? I checked that they offer as many USB -preamps as there are manufacturers in the sound/computer industry.</p><p>Kind regards,</p><p>&nbsp;<br />Olli<br />&nbsp;</p><div style="clear:both;"></div>
