Better Than Golden

“…it is clearly a design, engineering, and sonic tour de force.”

“You don’t hear the high frequencies from its ribbon tweeter so much as sense them as an integral part of the
overall sound.”

“Transients started and stopped on a dime, but they never overshot the mark into zing or raspiness. Strings were silky smooth.”

“…the center image was so tight on two-channel material that you’d swear the center speaker was playing, even when it wasn’t.”

“The Platinum speakers do it all here, with full-bodied, extended bass without bloat, a natural midrange, and crisp, precise highs without edginess.”

“…the Platinum system’s ease and lack of strain during the soundtrack’s greatest challenges blew me away.”

Platinum 5.0 Surround System - reaching for the stars

"Need a massage for your eardrums? The new Monitor Audio Platinum series will spoil the auditory canals in a very special way thanks to its excellent sound characteristics. The surround presentations give you such a goose bump feeling, which is only possible with absolutely exceptional  systems. The excellent tuning between the front and centre speakers supplement themselves in the multi-channel operation to  an unbeatable, harmonising team and increase the listening pleasure...whoever would like to reach for the stars in their home cinema should  make a listening appointment at the MA Platinum."
