Although the budget was relatively low, our ambitions were great because QLS has always been committed to creating products that are irreplaceable in the market and truly bring value to users. For the QP02 product, it cannot be replaced by mainstream linear power supplies already on the market; it needs to provide more value in terms of sound.\u003c\/p\u003e\n\u003cp\u003eHowever, when we started the research and development, we found that we had overestimated ourselves. The cost of the power supply was too high. To make it better, every component was expensive, and the cost gradually increased. We found that the cost of components alone far exceeded $200. We began to question whether we should continue with the project. If we were to pursue excellence, it meant we couldn't cut costs. In the end, we were convinced by the sound performance of QP02. We designed it at this cost without considering return on investment.\u003c\/p\u003e\n\u003cp\u003eBecause when we grow old and look back on our lives, we usually regret not having done anything, rather than regretting what we have done. Therefore, the QP02, priced at $600, was born.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0888\/2348\/files\/2_1732f92c-5f98-4018-8f08-5a21dccb707c.jpg?v=1777935719\"\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eWhat are the differences between QP02 and other linear power\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eElectricity is the mother of sound, and the power supply is the key to determining the equipment's sound quality.

Whereas most HiFi equipment only has a power consumption of 10-20W, QP02 is designed at 80W, leaving plenty of room for extra power.\u003c\/p\u003e\n\u003cp\u003e2. QP02 uses only high-end components from beginning to end, ensuring that the upper limit of sound quality is high enough.\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eLeave sufficient headroom for high volume\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eWe have found that the power reserve of the power supply must be sufficiently large in order for the upper limit of the volume to be high enough. When the power reserve is large enough, the most obvious change is that the sound field will be larger, the sound details will be more abundant, and the overall sound will be fuller, more stable, and atmospheric.\u003c\/p\u003e\n\u003cp\u003eUnder the premise of power consumption of less than 20W for general HiFi equipment, we have used an 80W toroidal transformer, 6A Schottky rectifier diodes, voltage regulators with a 5A output current for each path, and a DC output power cord that can withstand a 8A current for the QP02... we have left sufficient headroom for all of them.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0888\/2348\/files\/3_96b38ab3-7d3a-4d57-80e8-1673a64d5df3.jpg?v=1777935794\"\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eFull use of high-end components\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eMany friends also enjoy using HiFi cables and fuses. A single HiFi cable can have such a significant impact on sound quality, and this is even more important for components used in power supply, as electricity is the mother of sound. Experience has shown that almost every component in the power path has a significant impact on sound quality.\u003c\/p\u003e\n\u003cp\u003eTherefore, the materials used in the power supply must not have any weaknesses, and the QP02 is a linear power supply composed entirely of high-end components, from the Swiss Schurter power socket and fuse, to the Nuvoten Talema toroidal transformer from Ireland, to the Vishay high-current Schottky rectifier diode, Philips large electrolytic capacitor, Linear LT1084 high-current low-noise power supply regulator chip, Welwyn resistor, Siemens non-inductive film capacitor, Vishay MKP1837 capacitor, Wima MKP10 capacitor and DC-1X DC power cable...all are high-end components. It is only when every piece of wood in a barrel is long enough that more water can be stored, and using high-end components throughout the entire process is the foundation for improving the sound ceiling.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0888\/2348\/files\/4_d3825152-977a-4dd6-9c01-8e36b66e534b.jpg?v=1777935828\"\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eVoltage Regulator Circuit\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eThe power chip of Linear Technology (LT) is known as having no other drawbacks except being expensive. It is a regular guest in some military and industrial automation applications that require very high standards. Besides having low noise and high performance, its delicate, stable, and pure sound performance is also outstanding, which makes it a frequent guest in many Hi-End products from brands such as Weiss, DCS, Goldmund, and darTZeel.\u003c\/p\u003e\n\u003cp\u003eEach output channel of the QP02 uses an LT1084 regulator from Linear Technology. This regulator can continuously output a current of 5A and has a line regulation of 0.015% and a load regulation of 0.01%. This LT1084, which is several tens of times more expensive than regular voltage regulators, is superior in performance reliability and sound performance compared to many other brand voltage regulators and most voltage regulator circuits designed with discrete components.
