Three new products, all the same price British hi-fi brand, Quad, has launched its Platinum Series of high-performance audio electronics. First out of the blocks is a generously specified CD player/DAC/preamp called the Platinum DMP, together with two power amplifiers the Platinum Stereo and Platinum Mono. The Platinum DMP (Digital Media Player) incorporates a high-quality CD transport constructed from die-cast aluminium and ABS compound with a construction designed to reduce noise and vibration through damping of the mechanical components. From the CD mechanism, data is passed to twin Cirrus Logic 24-bit/192kHz Delta-Sigma D/A converters. This DAC configuration utilises the D/A converters in double differential mode with a dedicated D/A converter to each channel. A high-precision master clock is placed locally to the DAC circuitry to minimise the occurrence of jitter. In addition to CD, the DAC circuit can handle audio data from external digital music sources, converting data of up to 24-bit/192kHz. There are six digital inputs (3x optical; 2x RCA; 1x USB) and four digital outputs (1x optical; 1x RCA; 1x BNC; 1x AES/EBU). Analogue outputs are provided in two forms: balanced XLR and single-ended RCA. Post-DAC filtering is carried out via linear phase active filters with audiophile-grade FET op-amps. A fully differential signal path feeds the balanced XLR outputs, while both the XLR and RCA outputs can be independently configured for fixed or variable level operation (variable output enables volume level to be controlled via the DMPʼs aluminium remote handset). Quad suggests and why wouldnt they - when it comes to amplification, the Platinum Stereo and Platinum Mono are perfect partners for the Platinum DMP. As their names suggest, the Platinum Stereo is a stereo power amp that delivers 150W per channel into eight ohms, while the Platinum Mono is a monoblock design with a rating of 180W into eight ohms. The specially designed Platinum output stage accommodates a large number of output transistors, each one driven from its own driver transistor to maximise linearity. This unusual output section, says Quad, enables virtually flat output impedance to be presented to the loudspeaker across the frequency domain. Quad has undertaken research into electromagnetic interference inside amplifiers and both new power amps pay particular attention to the control of crosstalk and the flow of magnetic fields. There are new PCB layouts to screen signal paths, while custom-made transformers protect amplifier boards from magnetic interference and hum induction. Both the Platinum Stereo and Platinum Mono sport a choice of connection terminals of balanced XLR and single-ended RCA inputs and gold-plated speaker terminals to accommodate single or bi-wiring, according to the userʼs requirements. A 12V trigger is also provided, enabling the amps to power up and down automatically in line with the Platinum DMP. The Quad Platinum DMP, Platinum Stereo and Platinum Mono are available from September, with an SRP of £2499.95 (inc. VAT) per component. A separate preamplifier, the Platinum Pre, will launch later this year.
