What customers say
Customers hold the Mark Levinson No. 27 amplifier in high regard, focusing primarily on its enduring sonic purity and exceptional build quality. Owners consistently praise its neutral, authoritative sound signature, noting superior control, especially in the low frequencies. The dual monaural architecture contributes to expansive sound staging and clear channel separation. Beyond performance, the engineering is legendary; the unit is described as incredibly robust and built for longevity. While these vintage components may require servicing, the consensus is that the No. 27 remains a reference standard. It offers outstanding value, competing favorably against much newer, more expensive designs for audiophiles seeking classic, high-grade performance.
Know before you buy
The dual monaural design means the left and right channels are completely independent, each with its own power supply and circuitry. This minimizes crosstalk and interference, resulting in a wider soundstage and more precise imaging.
Yes, the No. 27 is designed to handle demanding loads. It delivers 100 watts per channel into 8 ohms, doubling to 200 watts into 4 ohms, and reaching 350 watts into 2 ohms, providing the current necessary for speakers with complex impedance curves.
This specific unit has been fully serviced and tested to meet its original factory specifications. This ensures that the internal components are performing as intended and that the amplifier meets the high standards of its original 1989 release.
The No. 27 features both XLR and binding post inputs, making it compatible with a wide range of high-end preamplifiers. Given its input impedance of 50k ohms, it will pair well with most modern and vintage preamps that have low output impedance.
The amplifier is quite substantial, measuring 17.5 inches wide, 7 inches high, and 18 inches deep. Because it weighs 75 pounds and utilizes a robust heatsink design for cooling, ensure your rack or shelf is sturdy and has adequate ventilation space around the sides and top.
Class AB amplification provides a balance between the efficiency of Class B and the low distortion of Class A. It delivers the refined, high-fidelity sound characteristic of Mark Levinson gear while maintaining enough power to drive speakers with authority.
