Sound United today announced a firmware update that brings IMAX Enhanced technology to a five AV receivers and a preamp/processor from Denon and Marantz.

The firmware update is being pushed out to a half dozen lower-priced models starting today, including two Denon AV receivers: The AVR-X6500H ($2,199) and AVR-X4500H ($1,599).

Marantz is adding IMAX Enhanced to its AV7705 preamp/processor ($2,199) and three AVRs: the SR8012 ($2,999), SR7013 ($2,199), and SR6013 ($1,499).
