CY-1ET7040SA-03 Pro 3-Channel Digital Power Amplifier
CY-1ET7040SA-03 Pro 3-Channel Digital Power Amplifier
HOT!NEW!
CY-1ET7040SA-03 Pro is a spectacular three channel digital power amplifier in our Pro 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 linear 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 Pro Series is supplied by 3 pcs of Hypex SMPS1200A400 switching power supplies that perfectly match with the 1ET7040SA, creating a true triple mono design to maximize its performance 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 Pro 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, including red copper speaker post and power IEC inlet from Furutech. Independent from the power IEC inlet, the audiophile-grade Schurter fuse socket also allows customers to upgrade with different types of audiophile-grade fuses according to their own preferences. Benefiting from internal structure of the modular configuration, Op amps can be replaced with equivalent Sonic Imagery 990Enh or the cutting-edge Weiss OP2-BP 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. In order to allow users to have a better experience during the operation, most of the functions of this amplifier can be controlled through the LCD display button on the front panel, such as system on/off, gain setting, input selection, etc. In addition, all of our Pro Series cases are treated with an anti-fingerprint nano-coating that not only prevents fingerprints, but also adds a touch of sparkle to its appearance and provides better protection. Lastly, all of our amplifiers also employ a new symmetrical internal and rear panel layout to keep the internal wiring as short as possible.
