Creek Audio’s 4040 A Integrated Amplifier Celebrates the Past While Looking Forward

The Creek Audio 4004 A Integrated Amplifier celebrates 40 years of audio engineering success while looking forward into the future.

Creek Audio 4040 A Integrated Amplifier Front

Creek Audio has been in the fight for 40 years and when it launched its first amplifier, the £99 Creek CAS4040 back in 1982, it created quite a stir. Mike Creek started his quest almost a decade earlier, and has managed in a rather understated way to offer some of the best affordable integrated amplifiers and phono preamplifiers available.

The brand has not been aggressive on social media which has kept it out of the spotlight, but that doesn’t negate the inherent value present in all of its products; Mike Creek builds really solid audio components. You would be hard pressed to find those within the industry who will dispute that; some of us wish that he would be more forthcoming with review samples but we’re working on that aspect of the story.

2022 ends with a blast from the past in the form of the new Creek Audio 4040 A Integrated Amplifier. The 4040 A is a rather compact integrated amplifier with streaming capabilities thanks to support for Bluetooth aptX HD and a myriad of digital inputs for network and CD players.

The Creek 4040 A also offers support for MM and high-output MC carts with an optional plug-in board.

Control: The 4040 A’s intuitive user interface and the sophisticated menu system is easily navigated either by remote control or rotary control knobs.

Pre-Amplifier: The “Feature Rich” 4040 A contains three analog signal inputs, including two pairs of unbalanced RCA sockets and one pair of fully balanced XLR sockets. The electronic volume control enables precise 1dB adjustment over a 70dB range. Left/right balance, tone controls and EQ settings, further enhance its flexibility.

Phono: Compatible with an optional plug-in Sequel mk4 Phono Pre-amp in place of Aux 2 to match a wide range of Moving Magnet and high-output Moving Coil cartridges.

Headphone Amp: A dedicated headphone amplifier will drive a wide range of headphones via a front panel-mounted jack socket.

Digital Inputs: USB, coax SPDIF, optical Toslink, USB class 2 and aptX Bluetooth 5.0 increase the flexibility of this amplifier.

DAC: The 4040 A leverages the power of a premier grade ES9023 Sabre DAC to convert digital signals into analogue.

Power Amplifier: The 4040A employs cutting-edge MERUS™ technology to enable it to drive even the most difficult loads to realistic listening levels with high fidelity.

Power Supply: The key to the 4040A integrated amplifier’s impressive performance is in its high-frequency power supply, optimised for audio electronics, enabling the latent quality of its amplifier to be realized. The 4040A’s performance is unaffected by mains quality or voltage stability.

Unlike most conventional amplifiers, its 250-Watt power supply is voltage stabilized, enabling it to double its power output each time the load impedance is halved, regardless of the mains voltage.

Energy Savings: Signal sensing enables the 4040 A to reduce power consumption by powering down non-essential circuitry when not required.

    The dimensions listed do not make sense to me. I noticed that they are the same on the Creek website. Assuming the 3 inch height is correct, it would seem by just looking at the front that it can’t be much more than 12 inches wide. Something seems amiss to me. Any thoughts?

      It is a very narrow piece and I also raised an eyebrow when I saw the image on the website.

      I’m following up with Mike Creek for some info.

    Looks like a bit of competition for the Rega io but with more bells and whistles.
    So what’s the price ?
