I recently purchased an Eversolo A8 streamer that has the latest AKM Velvet chips. I also have a Gustard R26 (R2R) that I have comparing the two.
I too like the sound of AKM having owned the E30 prior to the Gustard R26.
I must say, the Gustard R26 and the new Velvet AKM 4191EQ, AK4499EX chips are very close. I could easily live with either for the long term.
I would defintley lean toward the Gishelli at that price.
