So here we have a new condenser, vocal microphone on the scene proving very popular with the vocalists and engineers in the London clubs. With the regular industry standard vocal mics in use daily, it probably is hard for vocalists to try using new gear. Of course, the sound quality is the number one thing that they should be concerned with during their performances.
Here in Canada, I have not yet worked with any musicians, or artists that are currently using the DPA d:facto microphones. It is the usual suspects like Shure, AKG and Sennheiser in regular use. Maybe these DPA microphones with gather some attention "on our side of the pond.", once engineers here get a chance to try them out on a show.
I remember the first time I mixed show using Audix microphones instead of Shure, I did noticed a difference kind of vocal sound in my mix. Now Audix mics are becoming just a popular as the industry standard Shure mics on shows. Maybe DPA d:facto microphones could be the next popular standard vocal mic of choice.
Here is a link to an article that I found on the Prosoundweb site talking a bit about the DPA d:facto microphones in use in the London clubs.
