Oh your 7200's already have apodizing in them (possibly better than HD621). BUT ONLY if they are fed 44.1Khz or 48Khz. They must be upsampling to apodize. That is, the yellow light must be OFF for apodizing to be ON. As crazy as that seems. You should do some searches on apodizing. Make sure you set time to "Years" when doing any searches. There are LOTs of discussion on this very topic.

If you think listening to music is fun, try learning an instrument.
