Those stands are really nice.
Does the adapter plate work on them?
I don't believe the adapter plate will work, but I ordered them anyway. I was looking at the Stand 20s, as well as the Solidsteel SS-6 and then the FS206. All seem to be great stands for use with the Heritage Specials.
My dealer suggested that with either of the last two options some Blu Tack would do the job. That said, I would have to imagine that the Stand 20 / adapter plate solution makes the most sense, but, I'm not a particularly sensical person
Like you, I'll be using these at first in a larger room, and eventually with subs. Also like you, the Heritage Specials seemed to me like a way to atone for missing out on the Special 25s and classic Contour speakers. I've happily run Focus 160s for years, and will continue to do so in my office, but if Dynaudio had asked me for what I wanted in a speaker, it would be the Heritage Specials.
So, thanks very much for starting this thread here and sharing your experiences. I don't anticipate that these will be my "last" speaker, as the above reviewer claims, but I do hope to build a system around them I keep with me for the long haul. Here's hoping they bring everyone in this little club years of joy.
