The latest neo ribbon VMPS is much better than the Super Tower R, a design going back a long ways. I have only heard the RM-40s but I am sure that the Super Tower III's would at least be competitive with Pipedreams. You may want to listen to the RMX Elixer model. It's the latest and only cost around 10k.
VMPS Super Tower III vs. Pipedreams
I hear great things about both speakers. Anyone have thoughts of comparison? --or Do you even consider the VMPS Super Tower III's to be of comparison to the Pipedreams (6', 7', or 8')?
