I have listened to the following op coupling caps in L4.5 / L7 / GG:
- soviet military pio
- vcap cutf
- clarity cap mr
- duelund cast cu
- jupiter copper
- jupiter copper with duelund silver bypass
On a B7 / GG, you can't go wrong with either the factory fitted jupiter copper foil or duelund cast ag/cu hybrids. The latter would be my preference since they are a little darker and fuller, though that is a personal preference.
Readers may find this cap review of interest, though perhaps consider what is used in your preamps and our tweeters
