I've been using the ATV2 since it was released. Once I switched to a wireworld SuperNova 6 glass toslink cable, it equaled my CDP in sound quality. I did extensive A/B testing with the CDP hooked to my DAC1 and the ATV2 hooked to my DAC1 playing identical material. Then switched back and forth for instantaneous comparison. With a good cable, ATV2 equaled CDP to my ears. Sold CDP right after that.
