Anthem STR Power Amplifier (Black)

”I have been blessed to review a lot of really cool amps recently and I would consider the Anthem STR some of the best Class AB amplification that I’ve gotten my hands on in terms of overall performance regardless of MSRP.” – ‘Home Theater Review – 5/5’.

Reference stereo sound from the AV pros
The Canadian company that’s world renowned for making some of the best AV equipment in the world, also produces stereo amps and, as you’d expect, they’re something special. The STR Power Amplifier combines huge power with elegant delivery for a sound that’s mighty yet delicate when needed.

Massive power
A quick look at the STR Power Amplifier’s specs tells you all you need to know about this powerhouse. The dual mono design uses 16 output devices per channel and is powered by twin toroidal transformers. Power output is a monstrous 400 watts per channel at 8 ohms and up to 600 watts per channel with a 6 ohm speaker load. Simply put, the STR Power Amplifier has the power for any speaker in any room.

Delivered with finesse
The STR Power amplifier is about much more than sheer brute force, however. The input stage uses eight, low-noise devices configured in a complementary active-load cascoded feedback arrangement. This reduces distortion and lets the most subtle detail shine through. Likewise, the lack of any rail fuses helps clarity by reducing resistance. Transistors in critical stages are hand-selected and matched – giving the most consistent sound between channels and the lowest distortion.

Better protected
Anthem’s ALM (Advanced Load Monitoring) monitors the receiver’s temperature, current and voltage output – protecting the circuits when needed. Unlike other protection systems, ALM is non-evasive, meaning it operates outside of the signal path and, therefore, doesn’t affect the sound quality.

Professional XLR, balanced inputs
More usually found in studios, XLR balanced sockets offer excellent noise resistance and a ‘locked in’ connection for the lowest distortion and most secure connection. The STR Power Amplifier offers a choice of these alongside the more usual RCA phono inputs.

Graphic display with meters
Watch just how hard your STR Power Amplifier is working with the output metres. The high quality TFT display also other device information such as Thermal, Load and Amp On settings. What’s more, the display’s generous size makes it easier to read from the other side of the room.

Supersize your system’s dynamic range and soundstage, with the awesome Anthem STR Power Amplifier.
