Know before you buy
The MTRS is exceptionally stable, designed to maintain performance even with complex, low-impedance speakers down to 1 Ohm. Its high-current Meitner Power Driver ensures it can drive demanding loads without compromising audio fidelity.
By eliminating overall feedback, the amplifier avoids the phase shifts and timing errors often associated with feedback loops. This results in a more natural, open sound with greater sonic purity and transparency.
Yes, the MTRS is equipped with both balanced (XLR) and unbalanced (RCA) inputs, allowing for flexible integration into a wide variety of high-end audio systems.
No, the MTRS is a dedicated power amplifier. It does not include a built-in DAC, volume control, or remote, as it is engineered specifically to provide pure, high-power amplification for your speakers.
Given its weight of 180.62 pounds (82kg) and dimensions of 544 x 584 x 297 mm, you will need a very sturdy, dedicated equipment stand. It is not rack-mountable, so ensure your furniture is rated to support its significant mass.
No, the MTRS is a dedicated stereo amplifier and is not bridgeable. It is designed to operate as a high-performance two-channel unit.
