I like to sell this brand New, never used Stanton 500 AL II cartridge. The Stanton 500, Stanton 500 AL II, and Stanton 505 DK pickups belong to the category of turntable pickups often used by DJs, but there are differences between them: Stanton 500 • General use: One of the most popular DJ pickups, suitable for both mixing and general music listening. • Needle type: Elliptical or spherical (the exact type depends on the configuration). • Strength: Robust, durable, withstands long-term use. Stanton 500 AL II • Improved version: The 500 AL II is an improved version of the original 500. • Needle type: Rounded needle, which is excellent for scratching and mixing. • Difference: AL II has better tracking capabilities and offers optimized sound quality for DJs. Stanton 505 DK • Optimized for scratch: This model is specially designed for scratch DJs. • Needle type: Round needle, but requires more pressure for stability. • Difference: More robust construction, greater precision for fast movements, making it ideal for battle DJs and turntablists.
