Harmonic Resolution Systems

The technology of isolation and elimination of vibrations in audio system playback is no simple matter. The folks at HRS have lots of experience and hard science to back them up. Mr. Michael Latvis, has more than twenty years of engineering and product development skill with isolation systems for major aerospace and defense customers. He has worked for a number of leading companies on the development of isolation products for audio systems, commercial aircraft, military aircraft, and missile defense systems. Not to be taken lightly.

Proprietary techniques and custom materials are used to enhance audio playback and control any interference and artifacts. Dedicated craftsmen and extremely high standards of production make these products an absolute must in your hi-end audio system playback.

Detailed information on individual models and technical data are best found directly with the manufacturer. We invite you to connect with them here. We urge you to request specific demonstration or discussion with CDF directly for all of your questions.
