I would keep the Basic and cartridge then move to a better phono stage for the detail, like a Whest or Graham Slee or any of the ones mentioned above. Depends on your lp collection and how far you intend to go. If my lp collection was big i would go for the better tt/arm combo with same cartridge for start. Still you can sell yours at a reasonable price or trade and with your added budget you could have both.
