If a brand has some years behind it that is a good thing. The brand may not be known to you, but a track record over time is very beneficial.
There are exceptions to the rule, such as when a long-term manufacturer is sold to a new corporation and they implement lots of new procedures, etc. That can be just a problematic and a brand-new company without much of a track record.
Having some years to iron out simple unexpected problems is worth a lot considering the nature of audio electronics.
