M19 Reference SACD/CD I2S Transport

Power Player

Power is the heart of any product. The M19 power supply design was made by adopting two oversized independent linear power supplies with medical-grade toroidal transformers. One dedicated to powering the drive’s transport mechanical aspects, the motor drive and loader, and the other for the digital aspects and those related to the audio path. We wanted to make sure the two sections would be completely autonomous from one another and, importantly, supply stable, high-current power for the motor and mechanical aspects, ensuring accurate and stable motor speeds, and removing any potential cross-feed contamination between the drive and the rest of the audio path electronics. Both of which could be potential sources of jitter, and or power supply ripple.

Details make the difference

The M19 is crafted as one complete assembly in a milled aluminum chassis, with the benefit of having its power supply in proximity to the drive and digital output sections; this significantly reduces the possibility for any RF contamination, and most importantly ensures excellent isolated current delivery from the supply to the drive motor. It also removes any unnecessary cables and connectors, as one should note that this is low current, low voltage DC power, and this approach will achieve the best current delivery possible to all aspects of the device. As such, we believe that removing the power supplies from the proximity of the drive is of no practical benefit.
