"My philosophy is simply that audio power amplifiers should be as distortion free as possible, without severely compromising the performance of any other parameters" - G. Randy Slone
These ZUS Amplifiers
represents our Reference Series for those who wishing to experience the
highest
ZUS Audio
Engine™ performance. These amplifiers are designed with the TOTEM-POLE
Output Topology. The ZUS Audio Engine™ is tuned for the ultimate High Definition Audio
experience. Our Reference Series Amplifiers have Balanced XLR inputs as
well as Un-Balanced RCA inputs.
The performance of these amplifiers
are unmatched. Once auditioned, you will fully
appreciate what supreme audio is all about. Incredible. Amazing. Stunning.
Magnificent. The Power and the Glory.
