After having successfully introduced the award winning NHB series, darTZeel is now very proud to announce the new CTH-8550 full featured integrated amplifier. This new product combines in one casing most of the good things musical lovers found in our flagship series. The CTH-8550 features a newly designed power output stage - one per channel - which includes on board regulated power supplies for a very compact global layout. This new circuit brings outstanding transparency, speed, yet delicacy, giving a maximum listening pleasure. With no less than nine inputs in total, the preamplifier section is dual-mono one circuit per channel - with a minimal footprint which allows for very short signal paths. No doubt that this newcomer is a true darTZeel machine.

Security and customization

Each CTH-8550 is delivered with its own dedicated USB key which contains all customer information: owners name, serial number,  firmware versionVoltage range settings. The provided USB key will also allow for eventually updating either CTH-8550s firmware or software in the future.Casing

Entirely designed with a dedicated 3D-CAD software, the new cabinet is made from high quality, 2mm thick, Swedish Grade Steel. Starting with a plain steel sheet, it is cut with a high precision Laser Beam, then all parts are laser-welded together, even hand welded in critical areas, then hand polished and finished before being painted in an industrial oven. The result is just breathtaking. Aluminium heat sinks are sandwiched inside the steel structure, allowing for optimal thermal dissipation and extremely high global rigidity. The front plate is CNC-machined from a plain, 15 mm thick, aluminium sheet, giving the darTZeel CTH-8550 its incomparable finishing.

Colours

The darTZeel CTH-8550 is available in darTZeel standard colour.

On special request, it can also be delivered in full black, at no additional cost.
