George,
Why would you invest in a HD621 just for the apodizing filter while Mr. Stuart has recently promised us (again) that we will get a firmware upgrade for the G68 with the apodizing filter?
Tired of reading the drueling over the HD621 and waiting.
Then there will be arguments over which is better, and better to do it earlier in the chain etc.
One thing people have not considered is will the G68/861V4 have 6 Channels of Apodizing or 2

Even if ever does come.
But I'd like to validate some claims and what my ears can hear.
