I don't know. The logo does seem to be getting smaller. I believe there is a lot of pressure from above. ARC use to have parts for almost everything they ever made. This does not seem to be the case anymore.
The Ref 5se is the last true Audio Research looking Ref preamp. I was never really thrilled with some of the ARC designs. In my opinion the last truly good looking Ref preamp was the Ref 2mk2. I never saw the need for the display and I hated the plastic buttons on the Ref 3 and the Ref 5. But they were all clearly Audio Research. The new Mc-afide ARC pieces remind me of a Japanese imitation Harley. Just a bad copy of Mcintosh's styling. I don't see ARC deciding to do this on their own.
It just bothers me. I am not the Japanese imitation Harley type. I prefer the real thing.
