From what I can tell, this consisted of an add-on module inside the system, is this correct?</p><p>I was hoping that it was just an unpopulated area of the main PCB, but I guess this isn&#39;t the case.</p><p>I didn&#39;t really want to use an external amp, as the system&nbsp;will be&nbsp;mounted on the wall, and i&#39;ll be using a Beogram 3000, so there&#39;s&nbsp;no preamp in there.</p><p>Any ideas?</p><p>&nbsp;</p><p>Cheers</p><div style="clear:both;"></div>
