That’s interesting. One of my DAPs is the Hiby R8. So you think the Composer makes a difference of sorts?
Since you’ve obviously tried the R8 directly into the Soloist, what volume on each did you find you needed to reach for reasonable listening levels? When I set it up for the first time yesterday, at first I thought there was something wrong as I couldn’t hear anything with the R8 on around 35 on high gain and the Soloist on around 50 on high gain, driving my Odins. I had to crank it up to 70 on each. But on medium or high gain on the Soloist I get a lot of hiss on the Odins. That disappears at low gain, but then I have to crank it up even more to the point where there is no head room.
