I get where you are coming from chayro and I agree that power supply quality is of paramount importance. That being said, the progress in DAC chip power/capability/flexibility, digital circuitry, output stage design, etc plays a part too.
In this particular case (the LKS 004), it really is three things: the utilization of two powerful DAC chips in a dual-mono 2 channel configuration (vs, for example, Oppo using the same 2 chips, but with one for two channel mode and one for multi-channel mode in their 205), the elimination of op amps in the output stage (discrete), and the fact that a Chinese firm is able to design, build, and direct market a quality full-function DAC with high-end sonics/construction/feature set at a selling price 50% (perhaps up to 90%) less than past or even current established-brand products with comparable sound quality.
