P-037 and C-037 Have super thick (1.5micron) Silver plating directly on polished surface of receptacle and blade. Polishing process again (twice) on the silver plated surface, and then applied final Rhodium plating (0.3micron). Combination and thicknesses of plating represent the final sound character. Quality of polishing process influences the sound quality.
P-079, C-079 Are super thick (0.2micron) 24K GOLD plating directly on polished surface of receptacle and blade. Polishing process again (twice) on the 24K GOLD plated surface. Construction method is alike except direct 24k extra thick plating on polished receptacles and blades. Plating material and quality change sound dramatically. Where Rhodium sounds pure and strong, Gold sounds warm, soft and luxurious. Either, they both sound beyond standard. It’s up to you to choose for your type of sound and music.
