What a great experiment Birgir! Why did you choose LNS drivers? I know they are very smooth but not as fast as the 1 micron Lambdas. IMO the Orpheus are very fast and dynamic and the LNS might not be quite comparable speed wise.I believe Sennheiser deliberatly designed the Orpheus to be a diffuse type of headstage, which is great for large scale classical but perhaps not quite as good for small scale stuff like Jazz.Where on earth did you manage to source all those Orpheus parts from?
