Is the use of an iPod or iTunes played through one's middle to high-end audio equipment thoroughly frowned upon by the true audiofile? I currently have my entire music collection in iTunes (some recorded in Apple Lossless and some in MP3 VBR format). I really like the convenience of just pulling up a selction or Playlist and playing it through my home audio system. However, it appears that a lot of attention and concern is paid to the specs of individual components in the system. If I'm throwing in a PC or an iPod into the mix, am I completely negating the benefit of those other costly components; i.e. pre-amp, amp, speakers?
