Could you please post the link to that Youtube video? I’ve been searching for videos and music clips of Klangschiff harps forever to no avail (besides the three sample tracks on the official website).
I don’t have first-hand information on the Klangschiff harps, but I’ll share what little information I have. Most of the following information are in German. I could barely read them through Google translations. If you know German or someone who does, it might be your best bet to directly contact the people below for their opinions.
There’s an old webpage regarding an interview with the harp maker Lutz Bönisch. The page seems to be down at the moment though…

On the German harp forum (http://www.harfenforum.de) Alithe posted about testing several Klangschiff harps. She now owns an Athanasos model. In the same thread, another poster, Frenja, owns a Barden model (the “neo-Gothic” that you’re interested in). Both are happy owners.

Karstilo from the same forum posted about purchasing a used Matia Mou model from a private seller. The harp was made in the 90’s but held up well. Sadly the shipping process ruined the harp and the harp broke even further when the shipping company took the harp back to their warehouse to “inspect the damage” for the insurance claim. Karstilo once posted photos of the damages, but he has since taken them down. From the detailed photos (as an amateur) I could tell the harp was well constructed and finished.
