Before commenting on anything, price tag should be the first thing to consider. It is the cheapest groove on the market, by Numark which is a quite decent brand.
I mounted it on a cheap 70s turntable and used it with average Logitech speakers and occasionally with TMA dj headphones. The sound was always decent with no clicking in the high's. I was never disappointed by the sound output. I cannot say however how this would sound on a big sound system, but this is not supposed to be a requirement when you are on this price range. Is is meant to be for beginners in the turntables, with no audiophile expectations.
