Music Reference RM-10 MK2

(Click to enlarge) The RM-10 is a 6BQ5 / EL84 Amplifier, capable of delivering 35 Watts per side. Perfect for a small to medium listening room, the RM-10 is a very effective amplifier with unparalleled sonics in it's price range. This amp has received very good reviews in Audiophile Voice magazine. At Music Reference we are sometimes astounded at the waste and inefficiency of many current audiophile products. Whether a watt wasting, tube burning, distortion ridden, single ended design or a heat billowing silicon monstrosity, the concept and practice of waste and faddishness are anathema to our design practices. That’s why we were willing to devote four years of intensive research and development to the RM-10. It is our response to the failed efforts of others to produce an amplifier that at once sets standards of low cost, solid power output and wonderful musicality. In a world where 17 watts from a pair of 6BQ5 was considered the limit, designer Roger A. Modjeski has endowed the RM-10 with 35 watts from the very same pair of tubes. More good news is found in the eco-friendly nature of the RM-10 which uses only 70 Watts of precious electricity at idle. This convergence of economy and efficiency is further evidenced by output tube life that exceeds 10,000 hours. The RM-10 is a product for the music lover who appreciated the subtlety of music as well as its grandeur. Its 35 watts per channel will drive many of today’s loudspeakers to realistic levels in all but the largest rooms. We invite you to celebrate the RM-10; to view its subtle lines and glowing charm, as well as to wade in its simple, truthful way with music. Let it be your partner in the appreciation of music and the combined art and science of amplifier design. In an era where mediocrity and waste are common, we offer you an experience of utmost quality and enduring value. The RM-10 MK2 has improved output transformers which yields lower distortion at the higher frequencies and midrange, resulting in more detail. The RM-10 MK2 also features larger binding posts, which are now 1/2 inch. High quality components (such as Dale resistors) have also been incorporated into the RM-10 MK2.

1 Most audio amplifier do not even spec their hum, and those that do are not even close to this figure.
2 Noise and hiss is dependent on the 12AX7 driver tube. For very low noise (40 microvolts or less), you can use our Super Low Noise (SLN) 12AX7 tubes.
