The Audio Research CD6 utilizes quad 24-bit DACs running in mono mode, with dual master oscillators for highest performance; one for 44.1/88.2/176.4 sample rates, the other for 48/96/192kHz sample rates. Sample rate conversion is selectable for all inputs, allowing playback in native resolution or via upsampling, including compact disc and USB. Additionally, there is a selectable digital filter...[more]

The CD3 will not play back DVD video, DVD audio or SACD-only discs because it is our firm belief that the convenience of multi-format playback sacrifices sonic performance in the CD format. And, most customers and music lovers have extensive CD-based collections that continue to grow, so the priority on playback quality in this format, in our view, is eminently justified.While using the latest 24/...[more]

The CD3 has been a remarkable success since its introduction two years ago, clearly demonstrating how much musical information is buried in compact discs. In the face of emerging formats, the CD3 has proved that the billions of redbook discs in circulation remain vital in high resolution music systems. So why change such a good thing? Because the MKII retains the inherent musicality of the origina...[more]

Like the CD3 MK II the CD5 relies on the substantial Philips PRO2M laser mechanism with Audio Research’s proprietary mounting system and damping for ultra-low mechanical jitter. New high-performance circuit board material and an all-new FET direct-coupled analog output stage with beefy regulated supplies yield better performance that’s measurable: channel separation is improved from 92dB to 120d...[more]

With the advent of the CD5 and DAC7 in 2008, they knew that the DAC used in our Reference player needed a newer, higher-resolution version. (The new 24-bit, 192-kHz chipset is not retrofittable to the CD7.) And, their engineers found a way to physically incorporate the same power-supply regulation used in the Reference 3, using a single 6550C to replace two 6H30 triodes, giving better performance ...[more]

The CDA 822 uses a true 24-bit, high resolution, dual differential, digital to analog converter with current output for widest dynamic ranges, fast conversions and lowest noise. Jitter distortion arising from time errors is virtually eliminated by sample converters and our precision internal master-clock. Increased oversampling of 192 kHz is used to avoid the loss of energy and transparency i...[more]

The CDA823 is an evolution of the renowned CDA822 CD Player. While employing the same outstanding DACs and analogue amplifiers as its predecessor, double resampling and reading speed are now introduced. Increased over-sampling of 192kHz is used to avoid the loss of energy and transparency in a complex analogue output filter. The CDA823 also allows for future updates of firmware through flash progr...[more]

The new Top Loader CD player from Copland has employed psycho-acoustic modelling in the development of the upsampling filters which concentrate on eliminating the noise prior to each impulse. Copland chose the Philips CD-pro 2 transport, feeding double Wolfson converters running in dual differential mono mode,  with 24bit/192khz processing and a low-jitter master clock. Moreover, the DAC r...[more]

Special sound dampening material is strategically placed inside the unit to minimize mechanical resonances even further. Krell customized disc drive firmware enhances reading accuracy, drive mechanics, and operational parameter. As an ultimate final step, the separate SACD and CD laser heads are individually calibrated by hand for the precise output levels required for reference quality SACD and C...[more]
