       CY-1ET7040SA-03 MK3 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 latest generation 1ET7040SA modules, 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 1ET7040SA's capabilities, our custom-designed 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 a pure and clean 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. By using our built-in LPS-AUX03B-2V auxiliary power module, versatile power supply functions are implemented to make this amplifier even more powerful. The main function of this power module is to further improve the efficiency of the buffer board, taking the audio performance of this amplifier to another level. 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 stable current supply. To further bring the power quality closer to perfection, each set of power supplies uses an audiophile-quality linear power supply to power the buffer board, which perfectly complements its ultra noise reduction SS78XX/SS79XX voltage regulators, ensuring that the Op amps draw the purest and cleanest power in the entire power chain. In addition, a variety of efficient power management functions are also provided, including the ability to control the power state of the main power supply and support for 12V trigger control switch functions. The main power for this amplifier in the Regular Series is supplied by a Hypex SMPS3KA400 switching power supply, which fully utilizes the potential of 1ET7040SA.


       In the standard configuration of our regular series, each buffer board of this amplifier comes with a pair of studio-grade Sparkos Labs SS2590 full-discrete Class-A audiophile 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 990Enh upon customers request. Not just limited to Op amps, customers can also choose to upgrade other components, including power IEC inlet, XLR Socket and speaker post as well as Neotech 7N UP-OCC copper internal cable and other accessories. For even better performance, a true triple mono system can be achieved by replacing the existing power supply with 3 pcs of SMPS1200A400 switching power supplies so that when listening to songs with large dynamic ranges such as jazz or classical music, each channel has continuous of power supply. In addition, all of our amplifiers also employ a new symmetrical internal and rear panel layout to keep the internal wiring as short as possible.
