Arcam SA45 - Integrated amplifier with Class G and high-end streaming in focus

Arcam SA45 is built for systems where both power and finesse need to be in place. It combines Arcam's Class G amplification with an advanced DAC and a balanced circuit design that keeps the signal clean throughout the entire signal path.

The result is an amplifier that plays with ease, composure, and a soundstage that feels open and lively – whether you stream music, play vinyl, or use it with TV and home theater.

Highlights

• Class G amplification with 2 x 180 watts at 8 ohms
• ESS Sabre DAC with support for 32-bit/384kHz and DSD256
• Balanced circuit design
• MM and MC phono input
• AV bypass for home theater
• Balanced XLR and RCA inputs
• Powerful toroidal transformer
• Aluminum chassis with vibration damping

Class G with power and control

SA45 uses Arcam's Class G technology, which combines high efficiency with more natural and stable reproduction. The amplifier delivers plenty of energy, but without the sound losing calm or balance.

This provides reproduction with good dynamics, clear voices, and a solid low end – even with demanding speakers.

DAC focused on detail

The built-in ESS Sabre DAC handles high-resolution music files with great detail and low noise. The music is reproduced with more air, better separation, and a more natural coherence between the instruments.

Jitter is kept low through the internal signal processing, which helps preserve timing and focus in the music.

Ready for both stereo and home theater

SA45 fits naturally into both classic stereo systems and modern home theaters. AV bypass makes it possible to integrate it into a surround setup without compromising stereo sound.

The MM and MC phono input also makes it ideal for vinyl systems where you want to keep the signal path simple and direct.

Stable construction with low noise

The balanced circuit operates with low noise and helps keep the signal clean. The large toroidal transformer delivers stable power with minimal electromagnetic impact on the rest of the electronics.

The aluminum chassis also reduces vibrations and provides better working conditions for the circuits.

Built for modern hi-fi systems

SA45 combines classic hi-fi with modern features and flexible connections. It suits both digital and analog sources and serves as a strong hub in serious music systems.

It is an amplifier for those who want both power, control, and a more vivid connection to the music.
