From the press release:
Based on the No320S Preamplifier and a direct descendant of the critically acclaimed No32 Reference Preamplifier, the No326S features audio circuits, controls, architecture, and an optional phono module all adapted from the legendary No32. In fact, some audio circuits, such as the proprietary discrete volume attenuators, are identical to those found in the No32.
To offer audiophiles the highest signal purity, the Mark Levinson engineers have chosen to use an exotic circuit board material, Arlon 25, in the design and construction of the No326S’ main circuit board. By utilizing this material in the No326S, the team was able to conduct extensive listening evaluations and employ subtle component changes — the result is that the No326S yields an open, detailed sound with the engaging textural signature that only Arlon 25 can provide.
