   Reference Amplifier Model  RAM 285

From the heart and soul of Bob Carver. A legacy design to define State of the Art in audiophile tube amplifiers.
"The RAM 285 is the culmination of my decades of research in the field of designing amplifiers to sound their very best." "I really can't imagine anyone designing an amplifier that sounds better."
                                                                                              -       Bob Carver-

The RAM 285 is a simultaneously high voltage and high current design. The RAM will drive power hungry speaker like Magnepan to a glorious performance. In fact we use Magnepan speakers for the listening test of every RAM285 before leaving Bob Carver Company. For those who enjoy tube amps with highly efficient speakers, the RAM 285 is also great for you if background noise is an issue. Customers are reporting background noise levels lower than high quality solid state amplifiers. Our team of aerospace manufacturing engineers have leveraged state of the art technology in CAD and computer simulation to guard against the effects of EMI, high voltage creep and other causes of noise in lessor designs. The RAM 285 uses the latest space age materials to effectively solve the tube amplifier compomises of the past. The results are SNR of greater than 100, on par with solid state. Customer feedback about background noise reduction has been wonderful. The RAM 285 is Bob Carver design genius combined with the latest in aerospace manufacturing engineering and materials, delivering the best audiophile sonics of vacuum tubes, without the vintage compromises.
