I'm only using the Ayon Spirit II, no Ayon CD player. My system consist of a Denon DCM 290 changer plugged into a Valab DAC via stereovox digital IC then from the Valab to an Eastern Electric Mimimax using the Silent Audio Appollo ICs and also Apollo's to the Spirit II. Huge soundstage with very delicate highs, nice midrange and full bass. My speakers are the Legacy Classic and the cables are the Bogdan silver early issue. Right now I'm waiting for a new pair of ICs from SoundSilver. I'll post the results at a later time.
