Rome wasn't built in a day, but it sure burned in one

Let's see how they waste these two 9038Pro DAC chips (yes, the measurement results are very terrible)



This is the result of feeling lost and even angry. I mean, what should they do? How do they launch this junk product and sell it publicly? Shouldn't they be ashamed of it?

Previously I saw someone in this thread @Kane1972 requesting a measurement of Weiliang Audio 2019 DC300 DAC .The device is easy to purchase in China and is guaranteed an unconditional refund. So I ordered one from Taobao for measurement.The manufacturer is known in China for selling many "cheap and seemingly adequate" equipment. But in my experience, many of their circuit designs have serious problems. Especially the lack of basic design capabilities for digital circuits, which is why I only buy equipment with unconditional money back guarantees.As we all know, 9038Pro is an excellent DAC chip. Many DACs based on it have excellent performance-most of the highest DACs on the ASR DAC SINAD chart are based on 9038ProAudio measurementI took several measurements to confirm that what I saw was true. I tried to replace the cable / reconfirm the ground. The end result has not changed. You will see the measurement results under the XLR connection. The noise floor of RCA made me even more shocked.This is the FFT result of the noise floor of the RCA来自RCA的动态范围测量：Regardless, the remaining measurements are as follows:The process of taking these measurements made me uncomfortable.My advice: Never consider buying a DAC from this manufacturer. They will turn the best DAC chips into terrible products.There are many excellent manufacturers from China, such as Gustard TOPPING SMSL, etc., but this manufacturer is not included
