		<description><![CDATA[#10: i was being sarcastic more than anything.  what i was trying to get at is that even if you do make an amp with insane wire, ridiculous capacitors and resistors, and over the top connectors, it won&#039;t help your audio path if you&#039;re plugging a $35 cd player you got from wal-mart into the front end.  same with any computer&#039;s on-board sound card, all but the best pci sound cards or even most reasonable cd players.  &lt;br&gt;&lt;br&gt;my point is that to even start going down the road of trying to justify ridiculous wire and components, you&#039;d have to spend several thousands of dollars on ridiculous audiophile equipment and interconnects to even *think* about claiming superior audio &quot;tone&quot; or &quot;dynamics&quot; based solely on wire selection, all the while not having any shielding for your inputs as shown in the photos of this build.  and that isn&#039;t even touching on the issue of speakers and then speaker cables.  if you have anything less than insanity throughout, your insanity in your component selection for one part of the signal chain is obviated.  &lt;br&gt;&lt;br&gt;will i say that certain signal paths sound better than others...absolutely.  i put a mcintosh c28 in front of a tube headphone amplifier i built and it sounded like god compared to the tube pre i built.  there was definite difference.  this was coming out of an echo sound card though, with 320kb/s aac files playing.  my shitty mp3s still sounded shitty though, and just as bad.  and it wouldn&#039;t have mattered if i used monster cables or the cables i made.&lt;br&gt;]]></description>
