Quality creates brand, service creates value. As a well-known private enterprise, Chunyin has a professional testing system and a team of dedicated, skilled and innovative employees. Chun Yin’s engineers have been engaged in the design of audio products for nearly 20 years and have been pursuing perfect sound quality with rich experience. The product development has been rigorously tested, and the product is finalized only after our professional tuner adjusts the sound. CD-MU15 uses dual Es9038Q2M for decoding, one piece for each channel, which makes the whole machine more analytical. The op amp uses 4 pieces of OPA604, and the capacitors use high-quality capacitors such as Philips and Ruby. The tube adopts Philips 6922. The overall high-frequency slender hall is rich, the mid-frequency is full and smooth and sweet, the low-frequency dive is deep and flexible, and the control is good and will not be muddy.
