    Our engineering team in London invested hours researching, developing, experimenting and, above all, listening to ensure that CXA81 was right.

    Effortlessly Musical

    At the heart of CXA81 beats a Class AB power amplifier stage with optimised capacitor values. It takes the musicality of Class A and blends it with the efficiency of Class B. The amp’s short signal path is efficient, leaving little opportunity for interference. The resulting sound is pristine while delivering the emotional impact the artist intended.

    Power with Control

    Thanks to a generous toroidal transformer, CXA81 delivers a prodigious 80 watts of power per channel. Dual taps into the left and right of the amplification board mean that, in effect, each channel has its own power supply – resulting in a vivid sound stage. Dynamic shifts in music – like those loud then quiet moments – are handled with ease.

    • Superb Amp. I Can’t Stop Smiling

      "I bought this amp a week or so ago and cannot recommend it enough. The clarity, soundstage and depth are a giant stride better than my old amp. Everything is so tight and crisp. Digital or vinyl it’s like I’m listening to my music collection for the first time.”

    Great Digital Amp

    Great amp. Bought this primarily for streaming my digital music collection alongside streaming via Bluetooth from my TV.
    Works brilliantly with great sound and very little latency.

    Would recommend this to anyone looking for a digital HiFi amp.

    So impressed I'm going to purchase the CXN when budgets allow.

    CXA81 & AXC35

    Happy owner of the above models - paired with a couple of Bowers & Wilkins 607 Anniversary Edition - after 10 months of use thought a good idea to leave a review.
    The amplifier sounds amazing. Clarity, power and most important sound color you do not meet easy (I call it British sound ). Bluetooth connection working seamlessly with absolute no quality loss, not at least up to a low-mid volume level. Overall the system to perform needs a 10-15 min warm up.

    The CD player - used not at all very often - performing great as well. Big con: a couple of months after the purchase started - although on standby (not on) - receiving commands from a tv box set remote causing the cd tray to open and close every time I raise the volume. Contacted CA support, they suggested to re-program the TV set remote (something not possible). Nowadays has started to do the same this time while using the Apple TV remote.

    The reviews don’t lie

    This is an outstanding amp. It has all of the inputs you will need, a great sounding DAC, great sound quality, plenty of power, good quality remote, motorized volume knob, and it looks nice. I would give 5 stars if it had built in bass management for a subwoofer. I have it paired with my Dynaudio Evoke 20 and Dynaudio Sub 3. Sounds amazing.
