Excellent sounding Music Reference TUBE RM-5 MKIII preamp.
Known for it's musical sound.
Face, sides and back are excellent but top has minor scuffs and scratches.
Functionally excellent. Has MM phono stage.
Uses three 6DJ8 tubes. See photos for details.
Music Reference developed the RM-5 preamplifier based on sound
engineering principles following years of research. Our challenge was
this: How to provide excellent sonic performance at a price that
represents a great value to the audiophile.
sections of the RM-5 are the phono RIAA equalizer, phono amplifier, and
the line amplifier. Each active stage was designed with a power supply,
which exceeds its requirements, by a factor of ten. Thus, each stage is
ultimately over-load proof and stable under dynamic and line voltage
extremes. The result: an accurate sound stage with precise focus on
The RM-5 is built to standards well
beyond its price. All controls are custom-made and are plated for long
life and low noise. All chassis components are mil spec anodized.
Circuit boards are mil spec also. The RM-5 front panel lettering is made
by a process, which guarantees long life. Unlike most panels in which
lettering is silk-screened onto an anodized or painted panel, our Anofax
process puts the lettering into the aluminum with a two-color process.
Therefore, it can never wear off. Your preamp will look like new
forever. Our one-board construction, with minimum point-to-point wiring,
provides extremely high reliability. Control functions are logically
placed to facilitate easy connection and operation. Logic circuitry is
incorporated to drive the automatic and manual muting, assuring freedom
from switching noises, line voltage drops, and preamplifier power-up.
The rugged electrical and mechanical design assure years of trouble-free
use. And the fine sound delivered by the RM-5 will never become
