Performance ratings are just that, performance, not price. there are different ways of getting to a Class A performance, some very expensive, some not so much. If a small manufacturer tried to replicate the electronics of a high end japanese direct drive from the late seventies, the cost would be exorbitant, just because of the miniscule scale of sales these days. that cost would be spread over few units. But a manufacturer using a simple belt drive with an excellent bearing, heavy dampened platter and plinth might get equal performance results for much less cost. Both would have Class A performance, they just achieve that result in different ways. the cost relates to the method used, not the performance achieved.
