Further information: Location: Class A Audio, 8/585 Blackburn Rd, Notting Hill, VIC, 3168. phone (03) 8555 0735 The CX Series amplifiers are a labour of love; the product of a team dedicated to extracting every drop of pleasure and detail from music of all genres. Our amplifiers will help you discover a new dimension of sound. Cambridge Audio’s stunning new CXA60 delivers much of the CXA80. At the heart of it is the same high performance class A/B amplifier in a 60 Watt per channel specification. This is supplied by a single-winding low-flux toroidal transformer. Other than the additional USB Audio and analogue XLR inputs found in the CXA80, all other inputs and digital to analogue conversion is identical to the CXA80.

Further information: Location: Class A Audio, 8/585 Blackburn Rd, Notting Hill, VIC, 3168. phone (03) 8555 0735 The term “digital” is often erroneously applied to amplifiers with Class D (switching) output stages, but in the case of NAD’s new M2 Direct Digital Amplifier that word is appropriate. In fact, the M2 represents a major rethinking of audio-system architecture, directly converting standard-resolution or high-res digital bitstreams into signals that can drive loudspeakers. Functionally, the M2 is an “integrated amplifier” that replaces a DAC, preamplifier, and power amplifier. The M2 eliminates from a traditional signal path all the electronics of a DAC as well as the active analog gain stages of a preamplifier and power amplifier. It does this by converting the PCM signal from a digital source directly into a pulse-width modulation (PWM) signal that turns the M2’s output transistors on and off. That’s it—no digital filter, no DACs, no multiple stages of analog amplification, no interconnects, no jacks, no analog volume control, no preamp. The conversion from the digital domain to the analog domain occurs as a by-product of the switching output stage and its analog filter. This is as direct a signal path as one could envision. Specifications Continuous output power: 250Wpc (8 ohms); 250Wpc (4 ohms); 300Wpc (2 Ohms) IHF dynamic power: 300W (8 ohms); 450W (4 ohms); 600W (2 Ohms) Peak output current: >60A Signal-to-noise ratio: >120dB (A-weighted, referenced to 200W) Digital inputs: S/PDIF on RCA jacks (x2), AES/EBU (x1), TosLink optical (x2) plus TosLink in/out loop Sampling frequencies supported: 32kHz–192kHz up to 24 bits Analog inputs: Unbalanced on RCA jacks, balanced on XLR jacks Analog-to-digital converter: Fully balanced, 192kHz/24-bit Dimensions: 17.12" x 5.24" x 17.87" Weight: 44.45 lbs.

  11. Further information: Location: Class A Audio, 8/585 Blackburn Rd, Notting Hill, VIC, 3168. phone (03) 8555 0735 The Rocket 88 is very interesting from several perspectives. It uses a "Retro" design Cat's Eye tube for monitoring output level for each channel. You can see them in the photo above left. These are the round green "things" on the left and right side of the amplifier front panel. They were used on various products back in the 1960s, especially on tape recorders (they were reel-to-reel recorders back then). Only professional recorders had VU meters, and this was long before LCD recording meters that we see on modern cassette recorders of all price ranges. The Rocket 88 is switchable between functioning in Triode Mode (20 watts Pure Class A output per channel), and Ultra-Linear Pentode Mode (40 watts Class A/B per channel). There is a small toggle switch behind the far left KT-88 and far right KT-88 for switching each channel between these two modes independently, although I cannot think of a reason why I would ever use one channel in triode mode and the other channel in pentode mode. It may be just to keep the circuits as isolated as possible. Specifications Circuit: Push Pull, Balanced, Class A Triode, Class AB Ultra-linear Tube Compliment: Four KT-88 Output tubes, Two EL-84 Current Source Tubes, Two 6922 Input Tubes Power Output: 20 Watts RMS per Channel in Triode Mode, 40 Watts per Channel in Ultra-Linear Pentode Mode Inputs: RCA Single-Ended, XLR Balanced MFR: 15 Hz - 30 kHz ± 1 dB Output Indicators: Dual Cat's Eye Tubes Size: 9" H x 10" W x 18" D Weight: 42 Pounds

Further information: Location: Class A Audio, 8/585 Blackburn Rd, Notting Hill, VIC, 3168. phone (03) 8555 0735 The RS series of MOON audio components benefit from an even higher standard of manufacturing process than the regular MOON versions. All significant differences are contained within the circuitry and construction of each model. RS versions are built using different materials and parts in certain areas. For example, printed circuit boards are of a higher temperature grade than that of the military specification FR-4 material we normally use; Their traces are gold-plated instead of a tin/lead composite. As well, all capacitors use improved dielectric materials. Specifications Description: Solid-state, dual-mono stereo power amplifier. Inputs: 1 pair unbalanced (RCA), 1 pair balanced (XLR). Outputs: 1 pair WBT binding posts. Comms: RS-232 port, 12V trigger input and output. Rated power output: 150W into 8 ohms, 300W into 4 ohms, 600W into 2 ohms (all 21.75dBW).

  14. Further information: Location: Class A Audio, 8/585 Blackburn Rd, Notting Hill, VIC, 3168. phone (03) 8555 0735 The MP100 is the first dedicated phono preamplifier from McIntosh and is designed to help both new and experienced vinyl lovers get the most fidelity, performance and – most importantly – enjoyment from their albums. Like all McIntosh products, the MP100 is packed with features designed specifically for the vinyl lover including: Moving Coil and Moving Magnet inputs; Moving Coil and Moving Magnet adjustable loading (6 settings each); balanced and unbalanced analog outputs; optical, coax and USB digital outputs; and a Mono switch for when playing mono records to decrease noise and play the signal correctly. For pure analog use, the digital outputs can be completely disabled and powered down. There are many ways to integrate the MP100 into your audio system. If you’re new to vinyl and just building your system, it can become the main part of your setup. Or if you already have a system with an older preamp you don’t want to part with, the MP100 is an excellent way to add modern phono features. If you’ve got a home theater system and would like to add a turntable, the MP100 is an easy way to add full phono preamp capabilities without having to get a full-sized stereo preamp that would undoubtedly duplicate many of your home theater processor’s features. While spinning vinyl on a turntable is a great and unique way to enjoy music, there’s no denying the convenience of having digital versions of the albums. When used with a properly configured conversion program, the MP100 can “rip” the records to a computer via USB to produce high quality digital files. The digital outputs are fixed at 24-bit/96kHz to capture the full dynamic range of a record while optimizing digital file size. If an album has a very loud section, the clipping indicator will alert you so you can lower the digital output in order to produce a distortion-free recording. Compact in size at just 3” tall, it has many ageless McIntosh design cues. It shares the same 11.5” narrow chassis design as the MXA80 Integrated Audio System, MHA150 Headphone Amplifier and MB50 Streaming Audio Player to help build a cohesive system. It can also easily be added to a system comprised of standard, wider width chassis.
