This is an amazing sounding, well-built unit that performs like much more expensive units. Custom designed and manufactured by Technolink, it offers obvious sonic improvements over to the ever-popular TC-750. The circuit board is completely redesigned and incorporates 20 additional components and 1% tolerance resistors to achieve better RIAA and gain performance. It also has 2 dB higher gain to reduce the common “high volume control settings” at the stereo system compared to other input sources. Packaging is also changed to a simple black matte look to give a more “upscale” esthetic.
