Cayin CS - 55 A KT88 inkl. MM Phonomodul

The Cayin CS-55A KT88 is a tube integrated amplifier that combines classic tube technology with modern features, making it a perfect choice for audiophiles who enjoy using both analog and digital sources. With up to 40 W per channel in Ultra Linear mode, this amplifier delivers enough power for many speakers while still offering the warm, harmonious sound characteristic typical of tube amplifiers. Vinyl enthusiasts will especially benefit from the integrated MM phono input, which allows for direct connection to a turntable without the need for a separate phono preamp.

Technical features

The Cayin CS-55A KT88 impresses with its outstanding technical features, which process both analog and digital sources:

• Power: 2 × 40 W into 8 O in ultra-linear mode, 2 × 22 W into 8 O in triode mode, which increases flexibility in terms of sound characteristics and speaker matching.
• Frequency response: 5 Hz – 48 kHz (–3 dB), for a wide and dynamic frequency range.
• Total harmonic distortion (THD): 1% at 1 kHz, which guarantees high purity and detail in the sound.
• Signal-to-noise ratio (S/N): 92 dB, for excellent separation and clarity of the individual sound sources.
• Input impedance: 100 kO, which allows easy adaptation to different source devices.
• Output impedance: 4 O / 8 O (switchable), suitable for a variety of speakers.
• Tubes: 2 × 12AX7/ECC83, 2 × 12AU7/ECC82 and 4 × EL34 (interchangeable to KT88), allowing the sound to be adjusted depending on the preferred tube type.
• Dimensions: 360 × 334 × 180 mm, weight: 17 kg, a robust construction for a durable and stable device.

Phono MM module

The Cayin CS-55A KT88's integrated MM phono module is ideal for connecting turntables and ensures precise and dynamic playback of vinyl records. It offers the following technical features:

• Input sensitivity: 3 mV, optimal for most MM cartridges.
• Input impedance: 47 kO to ensure wide compatibility with various turntables.
• RIAA deviation: < ±0.25 dB, for exact reproduction of the vinyl signal.
• Signal-to-noise ratio: 68 dB, which ensures clear and detailed reproduction.

Sound quality and application

The Cayin CS-55A KT88 offers an exceptional sound experience, benefiting from tube technology and high-quality components. The ability to choose between Triode Mode and Ultra-Linear Mode allows you to customize the sound to your liking. Triode Mode provides a softer, warmer sound, often described as 'analog' and 'musical,' while Ultra-Linear Mode offers more precise and powerful reproduction with greater dynamics and detail.

The ability to choose between EL34 and KT88 tubes allows you to further customize the sound, as both tube types offer their own acoustic characteristics. The MM phono input is particularly interesting for vinyl enthusiasts, as it allows for a direct, high-quality connection to a turntable without the need for additional preamps.

Additional features

• USB DAC: Supports high-resolution digital audio transmission up to 32-bit/384 kHz via USB, allowing the amplifier to also serve as a high-quality DAC solution for digital sources.
• Headphone output: Front-facing 6.35 mm jack for headphones so you can enjoy your music even in quiet moments.
• Triode/Ultra-Linear switching: Allows you to change the sound character depending on your musical style and preferences.
• External bias indicator: Easy tube bias checking and adjustment ensures long tube life.
