darTZeel CTH 8550 MkII Integrated Amplifier - High-End Audio Equipment for Home Theater & Music Listening | Perfect for Audiophiles & Hi-Fi Enthusiasts

Until recently, integrated amplifiers only achieved distinction despite trade-offs in design.

Most integrated amplifiers have been built under budget and pricing constraints that leave little room for high performance.

That's why darTZeel is proud to present the CTH-8550, the first integrated amplifier without compromise.

With its dual-mono architecture, 50-ohm Zeel inputs, optional high-quality phono stages, and remarkable versatility, the darTZeel CTH-8550 is the integrated amplifier of choice for audio enthusiasts.

CTH-8550: at the heart of the music

With up to nine analog inputs for RCA, XLR, and Zeel 50-ohm cables, all sources including turntables are accommodated.

Boasting ample power reserve capacity, a wide range of functional features, and unrivaled ease of use, the CTH-8550 is the most complete integrated amplifier in its field.

Sound at your fingertips

The remote control is machined and milled from pure aluminum ingot, offering premium build quality and technology to enhance the user experience.
