The Creek Audio 4040A integrated amplifier ensures seamless functionality and opulent performance. Crafted to embody the spirit of the classic 1982 CAS4040, the Creek 4040A offers three analog signal inputs, comprising two sets of unbalanced RCA connectors and one set of fully balanced XLR connectors. Its electronic volume control enables meticulous adjustments in 1 dB increments across a span of 70 dB. Additionally, users have access to left/right channel balance, tone controls, and equalizer settings for a customizable audio experience.
Enthusiasts of vinyl music have the option to integrate the Sequel mk4 Phono Pre-amp plugin instead of Aux 2, accommodating a diverse array of MM and MC cartridges. The digital inputs encompass USB, coaxial SPDIF, optical Toslink, USB class 2, and aptX Bluetooth 5.0 connectivity. For the conversion of digital signals to analog, the 4040A employs the ES9023 Saber DAC.
The manufacturer stated, “The key to the 4040A integrated amplifier’s impressive performance lies in its high-frequency power supply, which is optimized for audio electronics.” The operation of the 4040A is not dependent on power supply quality or voltage stability.
Diverging from typical amplifiers, the Creek 4040A features a unique 250W power supply that is voltage-regulated. This distinctive design enables it to double its output power whenever the load impedance is halved, irrespective of the line voltage. The output power specifications for the Creek 4040A, weighing 2 kg and measuring 21.5 x 6 x 25.5 cm, are 35 W at 8 ohms and 70 W at 4 ohms for both channels. Available color options include black or silver.
