@mikeg I have never received and Ayon product on trade and I am not an Ayon dealer. If I get one on trade I will write it up.
@jimmy2615 my 204 arrived on Saturday and I will be writing up an evaluation of it. You are right that the Helios is using an 8 channel chip with 4 channels of processing dedicated to left and right channels. The 501/502 uses 2 channels of processing dedicated per channel and the 204 uses 4. I can say that the Helios is rather impressive with the deepest soundstage I have heard in my system, hands down. I also find it less bright vs. the 501 and incredibly smooth and detailed. It is between Playback and EMM in terms of Dynamics. It is in impressive unit That is priced well vs. what it is delivering.
I have the Lampizatior Amber 4, Weiss Helios, Weiss 204 and Innuos Pulse Mini to write up. We are not Lampizator dealers but have recently become Innuos dealers. I have heard insanely good things about the Pulse Mini so I am excited to hear it as an all-in-one streamer.
