The Starke Sound AD4.320

The Starke Sound AD4.320 is a true audiophile multichannel amp. Its unique ability to maintain consistent voicing while running in 4 channel, 3 channel, or 2 channel mode makes it perfect for home theater and critical 2 channel listening. Do you want to run a pair of stereo speakers? Simply bridge to two channels! How about the front soundstage for your home theater? Bridge 2 channels and operate in 3 channel mode with consistent voicing across all 3 channels! Did I hear you want to add 4 Dolby Atmos channels? Operate in 4 channel mode to add amazing impact to your cinema experience. This amp is truly unique!

NS600 Module

To give the AD4 true audiophile performance, Starke Sound’s electronics team developed the innovative Class D NS600 amplification module. This in house custom built module is unique to the Starke brand and isn't available in any other amplifier.
