Key Features
The IOTA VX SA3 is a robust Class AB integrated stereo amplifier with on-board Wolfson D/A conversion to offer you an instant audio upgrade. With a total of six analogue inputs, including in-built phono (MM) for vinyl enthusiasts, this amp is more than ready to become the centre of your hi-fi setup and it doesn't stop there!
Featuring digital inputs, a subwoofer pre-out and even packed with the optional Bluetooth adaptor for long-range control, the SA3 has everything you need for high-quality, high-fidelity audio. IOTA offers intuitive engineering to safeguard the purity of your audio signal, boasting low distortion and a vivid dynamic response.
The Bowers & Wilkins 607 S3 Bookshelf Speakers are a dynamic audio solution that offers a power-packed performance despite their compact size. Drawing from a wealth of British loudspeaker industry knowledge, most notably their partnership with Abbey Road Recording Studios in London and the audiophile-renowned 800 Series Diamond, the 607 S3 has been fitted with a new one-inch Decoupled Double Dome Titanium tweeter which is capable of delivering crystal-clear high-frequencies that capture much greater musical detail.
At the heart of these speakers lies the five-inch Continuum cone bass/midrange. This is a unique technology that boosts the 52Hz - 28kHz frequency response and delivers an immersive listening experience. This performance is also supported by the rear-ported cabinet design with Flowport technology that optimises the bass response, creating deep, low-end sounds that will add depth to your favourite songs. Thanks to its compact design, the B&W speakers provide superb sound dispersion in smaller rooms and great positional flexibility. You can also take your listening experience to new heights by placing these speakers on the FS-600 S3 Speaker Stands (sold separately) to reduce vibrations and improve the soundstage.

Let the SA3 be your hub for hi-fi. Featuring five Line-in connections, plug-and-play a wide range of audio sources including CD players, cassettes, network streamers and more. A dedicated phono (MM) input is also included, rounding the total up to six and providing a platform for retro turntable enthusiasts. A convenient subwoofer output lets you open the bass range of your speaker system and expand to a 2.1 home audio setup.
Express yourself. The IOTAVX SA3 is capable of producing confident vocals and an open soundstage. Hear instruments in more realistic detail. This amplifier can provide a continuous 50W two-channel power output at 8Ω load and up to 100W for hungrier 4Ω speaker systems. Thanks to the subwoofer output, your audio will sound full and responsive, qualities necessary for high fidelity audio.
As well as two-channel drive, the SA3 has also been provisioned with a Mono mode switch, making bi-amping a more accessible option for the curious and practiced alike. Working especially well with power amplifiers such as the IOTA VX PA3, split the output load and dedicate up to 180W (4Ω bridged) to speaker systems not usually compatible with amplifiers of this size. 12v triggers are also available for synchronised control.
Along with six analogue connections, the IOTA VX SA3 hosts both optical and coaxial inputs, letting you connect digital audio sources as well as providing you with an easy upgrade for television speakers and smaller screens, outputting a 2.1 audio experience.
Every ear is unique. That’s why having advanced audio level adjustment is critical for a modern home system. As well as volume adjustment from the front panel, treble and bass levels can also be set using the remote control. Tune music to your taste.
The SA3 has been packed with their intuitive Bluetooth adaptor, attachable via the extension port on the rear of the amplifier. This establishes a quick, wireless and distance streaming input for music via phones, computers and other compatible devices.
Please Note: It is important that the Amplifier Mode switch on the rear of the unit is set to Mono when bridging with external amplifiers. When set to Mono mode, the IOTAVX SA3 will deliver right channel audio.
