I would not call the issue overblown - it’s been noticed by many listeners in Singapore, Japan, Korea, etc. (i.e. countries in which there are multiple Solaris demo units within reasonably close proximity) - but rather that it is a non-issue for anyone who bought the Solaris already. The fact of the matter is that if you like how the Solaris sounds, including its mid tonality, then you should keep it, and if you don’t, then you shouldn’t. I can’t say whether the issue is persistent or has since been resolved by Campfire, but even in the worst case that it hasn’t, it’s really is only an problem for buyers who expect a certain sound after auditioning a specific demo unit. In terms of unit matching, CA has always been pretty solid.
