Upgrades that place the Rhumba Extreme above and beyond our standard Rhumba 1.3:

- Upgraded polypropylene capacitors throughout the power supply and gain stage.
- A dual-mono regulator in the power supply.
- Premium Terracones feet, from edenSound.
- A blue LED on the perimeter of the volume knob notifies you of volume position in low light conditions.

What is the sonic effect of these upgrades?
The Rhumba Extreme takes the big, beautiful sound of the Rhumba 1.3 and adds more midrange resolution. It has endless detail with smooth, never fatiguing levels of extremely high resolution. Imaging and microdynamics are also more accurate. As with the standard Rhumba 1.3, blue and red body color options are available.
