Spirit,
You're right, the Black Hole is effective if the problem you have is the one it solves. Since you already own one, you conclude it's still valuable to your system when you move to Def4. And at $1250 it is an affordable antidote to a vexing sound problem in some rooms.
Gloss finishes on Zu speakers come at a premium, so the maximum performance per dollar point is obtained with one of the stock matte finishes. If you have a rambunctious family, the matte finishes will be more maintainable. If your environment is serene, the gloss finishes seriously raise the perceived value of the speakers. You might look into ebay and Audiogon history for some data mining to see if there are patterns in value retention different for matte or gloss. I don't know. I have a 60" final gen Pioneer Elite Kuro between my Defs in gloss and distractions during movie watching aren't a problem for us. I can't say with a larger image cast by a projector. But it you are wary of visual distractions from gloss reflections, consider getting your hardware anodized black. Silver FRD rings and the big supertweeter lens are more noticeable than reflections, in HT. IMO, among the mattes, Cosmic Carbon looks more suited to the value of the speaker than absolute flat black, in a domestic setting. But if HT is your prime concern, matte black with black metal hardware, will vanish visually in the dark.
