Backert Labs Rhumba 1.4

The Rhumba 1.4 is our most surprising tube preamplifier. Fully balanced input and output. Jaw-dropping sound. The Rhumba sells for $5,000.

“$10K preamp performance for $4K.” (reviewing Rhumba 1.3)

“The Rhumba 1.3 is a fantastic preamplifier – period.”

“The most exciting aspect of the Rhumba is the lively, dynamic aspect of its sound.”

–TONEAudio Magazine

At $5,000, the Rhumba 1.4 linestage preamp has the same basic circuit design as our $12,900 Rhythm 1.4 flagship, including fully balanced XLR input and output. That also includes the same power supply design — our patented GreenForce.™

All in a gorgeous chassis. Like the Rhythm, the Rhumba is designed, machined, and assembled in the U.S., with NO farming out of the solid aluminum chassis to other countries.

From its debut, the Rhumba has wowed listeners. See reviewer Terry London’s raving preview of the 1st-generation Rhumba 1.1 including his stunning conclusion, “might be the best deal in high-end gear of the 21st century”.

His full writeup in Home Theater Review is found.

Improvements from the Rhumba 1.3

The Rhumba 1.4 has the following new features:

• two fully-balanced XLR inputs, rather than just one
• two fully-balanced XLR outputs, rather than just one
• improved circuit developments in the regulator portion of the power supply, which provides a larger soundstage
• improved circuit design in the gain stage, which provides a higher-resolution, more 3-dimensional listening experience
• improved stock tubes, which are NOS American-made tubes that are bursting with resolution and dynamics
• a new 3-button remote control that now includes a “mute” button
