The Audio Note (UK) Cobra Integrated Amplifier is capable of producing 28 watts per channel from a pair of EL34 valves operating in Class A push-pull configuration, which can provide improved efficiency and reduced distortion compared to other amplifier topologies.

This amplifier features an internal DAC, which can allow users to connect digital audio sources directly to the amplifier. This can provide a convenient way to stream high-quality digital audio from a variety of sources.

One notable feature of the Cobra Integrated Amplifier is its exceptional double C-core output transformers, which are custom designed and manufactured by Audio Note (UK). These output transformers can provide improved efficiency, reduced distortion, and high-quality sound output, allowing the amplifier to drive a wide variety of speakers with ease.

The Cobra Integrated Amplifier is equipped with a variety of input options to allow users to connect a wide range of audio sources. It features three analog stereo inputs, which can be used to connect devices such as CD players or turntables. Additionally, it has three digital inputs, which can be accessed via the onboard DAC.

The digital inputs include coaxial inputs, which can accept signals up to 24-bit/176.4kHz. However, it’s worth noting that the native bit-depth for the Philips TDA1543 D/A converter chip is 16-bit, so anything above this is truncated down. The optical SPDIF input can accept signals up to 24-bit/96kHz.

Lastly, it features a USB input, which can also accept signals up to 16-bit/48kHz. This input can be used to connect a computer or other digital audio source, making it easy to stream high-quality digital audio directly to the amplifier.

Overall, the Audio Note (UK) Cobra Integrated Amplifier with internal DAC and remote is a high-quality product designed to deliver exceptional sound quality and features for audiophiles who demand the best from their audio equipment.
