CY-1ET6525SA-03 3-Channel Digital Power Amplifier
CY-1ET6525SA-03/03T 3-Channel Digital Power Amplifier
HOT!NEW!
CY-1ET6525SA-03 is an extremely powerful three channel digital amplifier in our regular series, capable of driving high performance left, center, and right channel loudspeakers with demanding power requirements in a surrounding system. Powered by 3 pcs of Purifi Audio's 1ET6525SA modules, the successor to 1ET400A, this amplifier delivers extraordinary musical performance with its superb detail, resolution and soundstage, as well as ultra-low noise distortion and extremely fast transient response. To get the most out of the 1ET6525SA's capabilities, our custom-designed BB-SPL7879C-2F buffer board features the cutting-edge Sparkos Labs SS78XX and SS79XX discrete voltage regulators, eliminating any unnecessary noise and interference before the power reaches the Op amps of this buffer board, thus supplying extremely stable power to the module. Combined with a choice of Op Amps such as Sparkos Labs or Sonic Imagery operating in full Class-A, the sound is richer, denser and more delicate while adding warmth and depth. Benefiting from the continuous innovation of digital amplifier technologies over the years, our latest generation of amplifiers not only retains the unique sound characteristics, high efficiency power and lightweight size of provide digital amplifiers, but also provide sound quality comparable to traditional amplifiers on the market that are several times more expensive, whether they are Class-A, Class-AB or even other Class-D types.
To acheive the best possible sound from the CY-1ET6525SA-03, the quality of the power supply to the buffer board is one of the key factor. After continuous research and testing on the power supply by our R&D team, the following three requirements must be met in order to bring its performance to the next level: first, the power must be stable; second, the power must be sufficient; third, the power must be pure. The first requirement has been fully accomplished by adapting discrete voltage regulators with the most powerful noise reduction capabilities, while the remaining two requirements are fulfilled by using our specially designed LPS-AUX03B-2H auxiliary linear power supply module. With three sets of internal power supplies, it independently powers the buffer board of each channel to secure that the Op amps of each channel obtain the most sufficient current supply. To ensure that the Op amps draw the purest and cleanest power in the entire power chain, each set of power supplies uses an audiophile-quality linear power supply to power the buffer board, which perfectly complements its discrete voltage regulators, bringing its power quality closer to perfection. In addition, a variety of efficient power management functions are also implemented, including the ability to control the power state of the main power supply and support for 12V trigger control switch functions. As for the main power, this amplifier in the Regular Series is supplied by a Hypex SMPS3KA400 switching power supply, which fully utilizes the potential of 1ET6525SA.
Introducing its triple-power supply version, CY-1ET6525SA-03T, to satisfy customers who cannot compromise on any music details. This model is a true triple-mono system to ensure that the power supply of each channel is independent and does not interfere with each other, so that when listening to songs with large dynamic ranges such as jazz or classical music, each channel has continuous of power supply. In the standard configuration of our regular series, each buffer board of both models comes with audiophile-grade Sparkos Labs SS3602 full-discrete Class-A dual Op amps, and all connectors are equipped with our carefully selected high quality components. Benefiting from internal structure of the modular configuration, Op amps can be replaced with equivalent Sonic Imagery 994Enh or higher grade Sparkos Labs SS2590 upon customers request. Not just limited to Op amps, customers can also choose to upgrade other components before shipment, including power IEC inlet, XLR Socket and speaker post as well as Neotech 7N UP-OCC copper internal cable and other accessories. In addition, the existing single-power system can be upgraded to a triple-power system in the future by replacing the existing power supply with 3 pcs of SMPS1200A400 switching power supplies. Lastly, all of our amplifiers also employ a new symmetrical internal and rear panel layout to keep the internal wiring as short as possible.
