We are excited to announce that the latest member of our Qualiton Classic Series, the Qualiton X200 Integrated Stereo Power Amplifier is finally here and ready to production.
The Qualiton X200 is designed to serve analog enthusiasts who need a combination of a high-performance vacuum tube power amplifier and a versatile preamplifier, along with sophisticated technical details, built into a single chassis. In this way, perfect matching is achieved - both sonically and technically - between the main signal processing sections.
The most important aspect of the design process was to meet the widest possible range of user needs in a compact footprint. All internal circuits were designed from scratch, avoiding the usual clichés throughout, to create a complete all-rounder. The X200 can be used as a separate preamplifier, as an integrated power amplifier, as a stand-alone power amplifier with direct inputs, or as a headphone amplifier, but other configurations are possible.

The low noise analog front-end built around a wideband and transparent circuit and features a phono preamp with enhanced precision too. Line level and subwoofer outputs are absolute necessary in this category, these ports are included on the back. We've added a real specialty too: a built-in, studio grade Parallel Equalizer. This kind of tools is primarily used as a master channel effect in recording studios, to bring fresh air into the mix, as a finishing touch. We've found that this effect can also be a huge help at home as well, as it can breath new life into certain, not so vivid records.
The balanced power amp is based on KT120 (optionally KT150) beam tetrodes and our latest, fully symmetrical output transformer design. Due to the symmetrical circuitry, we were able to further reduce the output noise of the output stage. In addition, our new BIAS section on the front panel makes it really easy to check and fine-tune the bias levels of the output tubes.
