In many respects the design challenges are greater because the amplifier designer cannot be certain what speaker impedances will be encountered. To ensure the widest possible compatibility, our smart, fast amplifiers relish difficult loads.

Film soundtracks demand speed, power and wide dynamic range.
High performance music systems also need these attributes, in addition to an ability to convey low-level detail and a convincing sense of space. To meet these tough requirements the new 558 Multichannel Amplifier was meticulously designed utilizing the latest technological advances in the Meridian tradition of uncompromised performance. To deliver stable dynamics the 558 uses twin 1.2kVA toroidal mains transformers and no fewer than 50 pairs of hand-matched output devices. Its switchable bridged modes make it flexible and a precision topology brings nuance and delicacy to raw power. The 558 can be configured for either five channel output at 200W per channel into 8 ohms, or for two channels at greater than 500W into 8 ohms plus a single channel at 200W. For seven-channel applications it is possible to run two 558s with the front three channels bridged.
