Meridian 201 upgraded with Charcroft Z-foil resistors and Audio Note Kaisei caps.

Recently replaced components in the output stage of a modified Meridian 201 preamplifier have been given time to “bed in”, although from the onset it was clear that there was a noticeable improvement in sound quality. The resistors replaced Vishay bulk foils and the capacitors replaced Rubycons.
