LOL, if we’re talking about me, I concur. 
My amp was bright when I plugged it in. I’ve tried different cables and different combinations of SE, XLR, high gain, low gain just to see if I could get rid of the brightness. I think my experimentation may have caused some confusion regarding what I was trying to do, but I was just trying to see if I could tame the highs.
The only thing that worked was a set of cables that were unusable on my other amps because they cut the treble way too much, but they appeared to work some magic on the Jot.
No-one else appears to have that brightness issue, so I’ve emailed Schiit to ask for a replacement, only because I’d like to hear the same amp that everyone else is raving about. Schiit may say no, and to be honest, I’m not going to have a big fight with them, because it was only $399 and my EQ’d amp sounds fine driving my monitors, and I’m happy to use my other (better) amps for headphones. I told Schiit that I will continue to buy their products irrespective of their response.
I’d imagine everyone is sick of my story by now, so I’ll try my best to refrain from talking about the Jot, unless Schiit agrees to replace it, in which case I’ll let you all know how it sounds.
