Backert Labs Rhumba Extreme tube preamp preamplifier

The new Rhumba Extreme preamp from Backert Labs in factory new condition. A tubed line stage using radically new technology designed by amplification veteran Bob Backert. Two 12au7 tubes, a beautiful remote volume control, and 10dB of gain with just 75 ohms output impedance. The Extreme is essentially our $8,995 Rhythm 1.2 flagship placed into the less expensive chassis of the Rhumba 1.2. The Rhumba Extreme is an upgrade over the incredible Rhumba 1.2 in several ways: 1. Our proprietary automatic and continuous tube biasing, found in the flagship Rhythm 1.2, makes every tube you use in the Rhumba Extreme sound its very best 2. Premium Psvane tubes, for even smoother highs and just a light touch of warmth 3. Premium TerraCone feet, from edenSound ($95 per foot) 4. "Best of the best" output capacitors from Mundorf - their latest and most advanced 5. Upgraded polypropylene capacitors throughout the power supply and gain stage The Rhumba Extreme can be had with silver or black front plate. Body color is traditional black, or for $100 more we offer stunning red and blue color options. As with the "regular" Rhumba 1.2, the Rhumba Extreme propels dynamic, rhythmic, huge, clean and beautiful tubed sound from your speakers. Sound quality far, far above its price. The Extreme's smoke-grey tube access door lets you see the warm glow of your tubes during late night listening sessions, and gives you instant access for changing tubes, no tools required. Under the door, the protective enclosure around the tubes prevents young fingers from accessing the circuit board. Remote volume control. Three RCA inputs, one fully balanced XLR input.
