I had a Transfiguration Proteus before the Royal N and bought the Royal N because I expected it to be so different from the Proteus that I wouldn’t forever be comparing unfavourably, as I would had I gone back to my DV17D3. I ended up preferring the Royal N to the Proteus. When I eventually came to get the Proteus rebuilt I was offered an Ogura OA as originally fitted or two other profiles, one of which was a Gyger S (120/6).The Ogura would have been the sensible choice with regard to potential resale value but I opted for the Gyger on the back of what I was hearing from the similar Replicant 100 (100/5) and I can’t say I regret the choice. The Royal N has it on tone but the Gyger Proteus isn’t so far behind and has leading edge detail that the Royal N rounds off, going back will be the decider. Both dig out the emotional content from the music rather well.
