Frankly speaking as far as far as i can tell the new stealth is not by any means an upgrade unlike arya stealth. The major differences are less but more impactful bass, much brighter highs, smaller soundstage and recessed mids. Nobody can actually pinpoint if any detail or speed is gained as all people can say is its better than arya but worse than hekse, which is what they were saying about hekv2 original already.
