Sounds like my experience with all BA sets. My T800 just doesn't sound as good on tube as they do with SS IMO. I think you might be right about the ping. BA bass is a bit slower already (though not terribly so), and the tone is different than DD or ortho DD, so this could also come into play.My Sony ier m9 sound meh on the 13, JH Lola sound good not the best but the moondrop blessing 2 sounds great. The Sony and JH are better with the 11 amp and the 12 amp. Maybe the 13 amp isn't for me giving the tube ping when you switch iems and noise with streaming. Great idea the amp 13 just a bit too niche for me
Now with some other sets they just sound "right" to my ears (IT07, Chaconne, Deva, etc..) for just about anything I throw at them. As for the noise while streaming, I don't mind it all that much because it only lasts for a few seconds for me, then goes away.
Edit: Re read what you said, and I read it wrong the first time. Regarding ping, I was referring to time. Tube amps slow things down a bit.
