The first non-wooden bodied Koetsu.  The body of the Gold Pr is machined from a block of high quality Onyx stone.  Each block is carefully selected for natural grain and polished to a very fine finish. The use of Onyx results in the cartridge being one of the heaviest at 12g.  The coils and cores are very tightly matched among the production models.  The Onyx Platinum is als...[more]

The Inspiration 2 Integrated features an LCD touchscreen for easy access to every adjustment, with an elegant, machined aluminum remote control for key functions. Thanks to the resistor-ladder volume control, digitally controlled through a smooth-spinning volume knob on the front panel, the Inspiration 2 Integrated achieves precise channel matching impossible with potentiometers. The new Co...[more]

The Inspiration 2 Stereo and Mono use the same Line Stage Gain Module input stage found in our top amplifiers. Hand-matched, low-noise transistors combine with a servo circuit that corrects any signal balance inconsistencies. The Inspiration 2 amplifiers’ Constellation Link interface connects to Constellation amplifiers to remove one amplification stage from the signal path, resulting in ...[more]

The Line Stage Gain Module employs fully balanced, mirror-imaged circuits made with hand-matched, ultra-low-noise transistors. A unique servo circuit monitors the signal balance and corrects for even minute inconsistencies. If you use a Constellation Audio amplifier, you can feed the Inspiration 2 Preamp’s output to the amp’s Constellation Switched-Mode Power Supply (C-SMPS) pro...[more]

As with all the Platinum series of Koetsu cartridges, it uses a set of very tightly matched Platinum-alloy magnets. The body of the cartridge is carved out of a solid block of Jade.For such delicate work, Koetsu Japan specially commissioned a craftsman to handle the task.  The final design was chosen after assessing many prototypes. Koetsu Japan had long held the belief that the best way...[more]
