OK so the first subject is Stacking. Someone suggested to me that it's possible to stack two (or more) Black Discus. I found that a small amount of Blu Tack in between the discs worked to hold them together.
You can then use this as a single device, something like this:
I was impressed how well this worked with two discs. (Not going to bore you with any descriptions, as it will perform very differently on different systems.)
So I wondered how many you can stack. I'd just finished a batch that included 14 Mini BlackDiscus. I made a large stack with all 14 of them. It was somewhat precariously balanced on my headphone's jack plug.
How did it sound. Well, not very much different to a stack of two. Maybe a little - perhaps like a stack of three.
But note the lesson - stacking works, but best limit it to two. Or three if you are seriously mental ;)
