Not really limited if you asked me...
But the way Edifier promote themselves in the first place makes it hard for ppl to buy their high end product unless they really tested it in the first place. IMO Edifier should sent a few set of their high end speaker to highly reknowed reviewers to give end user better impression. Edifier has long been know as making affordable good speaker instead of high end speaker which is why ppl remain skeptic about their build quality and reliability.
