In addition to the 8200CD, the 8200CDQ adds full preamp functionality whilst maintaining the same chassis size as the 8200CD. The existing digital inputs are joined by three line-level analogue inputs, providing source selection and volume control in the analogue domain. The preamplifier section is fully balanced and all analogue input signals are converted to balanced form, helping to reduce distortion and noise. Class A gain structures are present throughout, and users may choose between preamplification in the analogue or digital domain in respect of the digital inputs. In addition, the 8200CDQ adds a direct-coupled, discrete, Class A headphone amplifier, accessible via a socket on the front panel. John Westlake leads the design team responsible for developing the 8200CD and 8200CDQ. Johnʼs technical skills have delivered award-winning digital audio products spanning the last two decades and a variety of companies have benefitted from his expertise. John is convinced that the 8200CD and 8200CDQ are the finest CD players he has ever designed.
