SUPPLIER
Power Supply Unit

Upgrade to
The "SUPPLIER" Power Supply Unit

Experience Bigger Punch And Increased Dynamics!

Every Audiophile knows that a source of clean, regulated power is essential for great sound.

The standard auto-switching PSU included with your Firestone component is a capable unit and will satisfy the needs of many listeners. The “SUPPLIER” upgrade on the other hand is a cleaner, higher powered unit. This provides the reserve power to follow the dynamic swings and crescendos in the music that the stock PSU might not be able to follow.

Electronics that are "power challenged" sound thin or flat at frequency extremes and don’t have the oomph to follow the peaks and large dynamic swings in the music. This is particularly noticeable when driving some of the more difficult headphones

This is a brand new SUPPLIER version, recently redesigned for even cleaner, more consistent power!
