Nobsound R21K Turntable Cartridge Alignment and Tuning Kit Review

The Nobsound R21K is a turntable cartridge alignment and tuning kit priced at $69.99. It gathers the tools needed for calibration and maintenance of a phono setup into one reasonably matched set, so cleaning and adjustment can be handled in a single session.

The kit's core is its measuring and alignment gear: a VTA azimuth ruler, an alignment protractor and a stylus force gauge. Used together with the five spirit levels (4 small, 1 big) that ensure the turntable sits horizontally, they help the stylus read the music information on the record more correctly, restoring the most authentic sound the maker says the system can give.

Maintenance items are included too — one record brush and one stylus brush for cleaning dirt and dust from their surfaces — along with screws, a screwdriver, a tweezer and four cartridge cables to make alignment and phono adjustment more convenient. A record adapter rounds out the set; the maker states it improves sound quality while reducing resonance and vibration.

Everything is packaged in a delicate silver box measuring 205x65x213mm and weighing 750g (900g packaged), which keeps the tools retrievable without hunting through drawers whenever calibration is due. Reaching accurate results still depends on the user following alignment procedure carefully — the kit provides the tools, not the technique, and it does not include cleaning fluid or repair parts for worn styli.
