I guess it's market-related. Your remarks remind me of Behringer. They make products for the music and audio enthusiasts. They have decent quality products at a very fair price that have been around for 10+ years now (like the X32 mixer) and apart from that, they churn out new products all the time (especially remakes of vintage synthesisers) to keep their users coming back and check out what's new.
