GR2 technology improves on our coreless story by removing even more micro vibrations and making way for improvements in the power supply,” wrote Technics US Business Development Manager Bill Voss, by email. “The progression from the legacy models to the new coreless models, which utilize higher tech and materials like magnesium in the G-model tonearm, zinc and special gel in the footers, and higher-grade plinth designs and improvements in tonearm sensitivity and ease of cable connectivity, laid the groundwork for audiophiles and allowed us to develop the more affordable, deejay-specific 1200MK7 and mainstream 100C/1500C models based on that technology.” As Voss mentioned, the GR2, which is built in Malaysia, features a new power supply, which the company calls “Multi-stage Silent”; it combines a “low-noise, high-speed power supply working at over 100kHz and a noise-canceling circuit inherited from our reference class SL-1000R turntable,” according to the Technics website. “This circuit measures the level of minute noise in the regulator output and cancels the noise by adding its inverse component current to the output,” Itani wrote. The website again: “By this method, a very low noise floor is achieved, enabling exceptional signal-to-noise ratio, improving the overall signal performance.
