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]

With the growth of the iTunes culture and the increasing popularity of storing music on a hard drive, Audio Research were asked repeatedly to offer a USB DAC that could connect with Macs, PCs and servers to deliver a new benchmark in high resolution digital music playback. Audio Research listened, and after more than a year in development we are excited to introduce the DAC7 digital-to-analog conv...[more]

The PH6 is a hybrid phono stage with a low-noise, high-gain JFET input stage with constant current stabilization and no overall feedback. Unlike its predecessors, the PH6 incorporates two high current 6H30 twin triodes in the gain and output stages; you can expect over 4,000 hours from the PH6’s tube set. Total gain is 58dB, more than sufficient for low output moving coil cartridges when ...[more]

Housed in a chassis the same size as the DSi200 integrated, the DS225 continues the design hallmarks of the DS450. Audio Research’s proprietary Class D all discrete analog switching mosfet output technology is again combined with a large, linear analog power supply, yielding tremendous speed and power delivery, but doing so with cool-running efficiency, idling at only 38 watts. The DS225 is ...[more]

The power supply is a classic linear, analog supply, heavily regulated and scaled up to provide explosive dynamics and impact. Its 1239 joules of energy storage are twice that found in the DSi200. Dynamic power is 900 watts into 8 ohms, 1800 into 4 ohms, and 2800 into 2 ohms, meaning the DS450 can control those big, tough-to-drive speaker systems. The output stage is a high-speed pulse-width modul...[more]

There are several reasons to choose the DS450M over its stereo counterpart. The most important is performance-based: a monaural amp simply produces a bigger, more spacious stage by virtue of the channels being totally isolated. Also, we were able to fit a much larger , power supply in the chassis. Then there is the issue of size: the DS450M is smaller and easier to situate than the hefty DS450 ste...[more]
