About the No. 26

The Mark Levinson No. 26 is a stereo preamplifier introduced in 1988, designed with a dual monaural configuration where left and right channels are completely independent. It features an external power supply (PLS-226) to reduce interference, and uses a unique matrix relay control to minimize signal path and switch contacts. The unit supports balanced XLR inputs and outputs, with three outputs (Main, Tape 1, Tape 2) and six inputs including tuner, tape, CD, aux, and a phono or auxiliary input. The preamplifier can be configured with optional phono cards (MM or MC) or a balanced input card, but only one expansion card can be installed at a time. It offers gain settings of 38/44 dB for MM phono, 58/64 dB for MC phono, and various gain levels for line inputs. The No. 26 delivers low distortion (THD and IMD less than 0.005%), high RIAA accuracy (0.2 dB), and a maximum output voltage exceeding 13 V balanced. Its build quality includes MIL standard parts and toroidal transformers in the power supply. Dimensions are approximately 444 x 333 x 76 mm for the preamplifier and 193 x 78.5 x 333.4 mm for the power supply, with weights of 4.5 kg and 3.6 kg respectively. The unit is highly regarded for its neutral, dynamic, and transparent sound quality, though it lacks remote control and uses CAMAC connectors requiring specific cabling.
