For music lovers craving "real music", not just good sound.

the digital analog converter for "REAL-SOUND", real-life soud



To reproduce realistic sound, an amplifier with excellent drive capability and a source device that reproduces tone color information without omission are required. RMP-DAC3EX reproduces a timbre signal full of musicality.

The sound concept of RMP-DAC3EX

"Realistic audio is the most beautiful".
This is why we strive for the most musicality in our audio equipment.

One of the most important factors for achieving realistic audio reproduction is "realistic tonality" of musical instruments .The violin must sound like a violin, and the oboe must sound like an oboe in order to faithfully convey the musical expression contained in the "performance."

This is why the design concept of reproducing the original recorded source information without alteration and spoiling is important.

Because the tonality of live musical instruments consists of minute harmonics that are intertwined in multiple layers, its reproduction is directly linked to musicality.

The DAC3 brings out the musicality of the performer by valuing the original timbre and expression of various musical instruments, especially the natural reproduction of minute signals.

Capacitor Blending for RMP-DAC3EX

HBIKIICHI is a capacitor developed in collaboration with Nichicon to bring out a natural sound and is also used in our amplifiers (pictured above on the far right).

In addition,DAC3EX features new capacitor "MR56"which increases the expressiveness of the midrange.

Furthermore, from the SPEC sound quality capacitor lineup, we have selected and blended capacitors to achieve more realistic sound reproduction than ever before.

R core transformer for energetic expression

A dedicated R-core transformer supplies the drive current of the output stage by a margin.

The DAC as a Musical Instrument

A DAC is a device that reconverts the digital signal into the analog signal,
In order to reconvert minute signals into fresh analog, the DAC3 has a separated power supply. The power supply, which is free from the vibration of the transformer and has excellent "musical expressiveness", surely conveys the musicality of the performer.

The wooden panel attached to the bottom is made of the same spruce material as the top plate of a violin. Spruce is a relatively soft material that vibrates with music signals to reproduce a rich tone and energy.

In addition, in DAC3EX, we have adopted a new shape and structure of a LEG. The structure in which HICKORY is embedded in the groove in the center of MAPLE optimally supports the main body chassis.

The ground surface is spherical, and by supporting the whole cabinet with points of hickory, we have created “the structure of the body that plays realistic music". The DAC3 is also built as an instrument.

By combining the RMP-DAC3EX with the Diretta RMP-UB1,
we can get closer to a more realistic sound.

A digital signal is converted to analog by the DAC device. In this conversion, the noise of the digital signal has an effect on the analog signal. It's small, but it's not zero.RMP-UB1 can minimize the influence of noise in this conversion. It's not a noise filter. By making digital transmission smooth and uninterrupted, the noise level is lowered.

This noise is a dynamic SN that appears when the sound is actually playing, unlike the static SN described in the specifications of audio equipment. This dynamic SN spoils the minute signals in the music, burying the delicate timbre of the instrument.
The Diretta RMP-UB1 greatly lowers the noise floor, so you can feel the timbre that was hidden until then emerges. That's the realistic sound.
