After many, many, many preamplifiers we have settled on the Backert Labs amazing preamplifiers. The combination with both the Wavelength and Tom Evans Amplifiers is superb. Please check out their web site for more information on these amazing preamplifiers, they are truly a revelation.



Our business is built on a unique concept:  that live music has a certain feel to it which stereo gear today has difficulty replicating. Our company is based on the search for truly live sound, and stands on the principle that dynamic and rhythmic accuracy are the keys to unlocking the magical feeling of a live performance.  While many companies do quite well reproducing tone, no other stereo system we have heard brings the true feeling of a live, right-now, happening-in-the-room event like a system using a Backert Labs preamp.

Bob Backert has been designing and modifying preamplifiers and amplifiers, particularly tubed equipment, for decades.  His modding business, which has long had a highly favorable following on the discussion boards, is RHB Sound Dezign. His designs are highly innovative, with a dedication to thinking outside-the-box in every key area of an amplification circuit that affects sonics.

Bob designs each of our preamps and builds them with his son, Gary Backert, who has been assembling audio circuits for most of his life.  Andy Tebbe, a pianist, drummer and singer in live bands for over 35 years, provides additional input on voicing / sound quality.  A reformed corporate attorney,  Andy also assists on the business side.

Once Bob designs a circuit, Gary provides the construction techniques to assemble it properly and securely.   Silver solder is standard.  The strictest attention is paid to wiring individual ground returns to prevent ground return feedback.

Backert Labs™ is pleased to present our Rhythm, Rhumba Extreme, and  Rhumba preamplifiers.  Each containing many “firsts” in the world of audio – and beyond.

Aluminum machined in Pennsylvania.  Chassis sheetmetal cut and assembled in the U.S.  Every unit, designed and built entirely in the USA, right down to the tube door that gives convenient access to your tubes, found on every Backert Labs preamp.  We are very proud of the work that goes into each unit.  We can’t wait for you to hear one in your system.
