The heart of any power supply is its capacitors. Similar to batteries, capacitors provide the power for your equipment to operate.
The GreenForce power supply employed in all preamps by Backert Labs is unique, in that it allows the use of extremely high quality capacitors to run the power supply.
In our Rhumba and Rhumba Extreme models, the GreenForce power supply uses very high quality polypropylene capacitors for extremely linear and nimble response.
In our Rhythm models, the GreenForce power supply uses the costly V-Caps™ copper/PTFE capacitors. Online capacitor comparisons such as The Great Capacitor Shoot-Out tend to rank V-Caps in first place (and that is with the tin version of V-Caps, rather than the upgraded copper version that we employ). V-Caps are made with an advanced polymer called PTFE or polytetrafluoroethylene which is better known by its brand name/trademark “Teflon”.
The Rhythm preamplifier is the only audio component in the world with an all-V-Caps or all-PTFE power supply. In fact, the Rhythm is the only product of any kind with an all-V-Caps or all-PTFE power supply.
The results: Incredibly fast transients. Tight, accurate bass with visceral texture and punch. Extremely accurate timing. Incredibly fast dynamic changes — dynamics that really tell the story of what is on your source material.
