Firstly, the reviewer is plainly wrong about K01-XD being the most expensive source from Esoteric. The Grandioso player is significantly more expensive. He's right about it being the best built digital player. The comments about its character being best compared to a high-class turntable, I think that is utter rubbish. I haven't heard a turntable character anywhere like an Esoteric digital source. Perhaps something got messed up in the translation. Or maybe the reviewer was padding it out for words. I wouldn't describe the Esoteric digital source sound being shaped in any specific way. The migration from AKM to FPGA microprocessors in Esoteric players produced another flavor of good. The algorithms Esoteric put into the FPGA's can certainly shape the sound in any way it wants. I had no criticism of the AKM DAC sound. Shaping of sound is far more at the mercy on the speakers, then the pre-amp, then the power amp. Cables have a bit to do with it also, but less so. I enjoyed the sound of my N-01. I enjoy the sound of my D1X. I don't really have a preference for one over the other. I have never found a quality source to make it easier to listen to music recorded in less than optimal quality. I lean in the other direction, the quality source is inclined to expose flaws in the recorded music that diminish the listening experience.
