I have the Schitt Kara. It's quite neutral and quiet. Having a passive mode is a big plus as I can use it as a remote volume control for pieces that don't have one. It's audio functionality is excellent.
However, there are two issues that are annoying. The remote has a very narrow range. You must point it directly at the hole. Even an inch or two away and it doesn't respond.
The other is its sensitivity to static electricity. A slight touch and it will go into some strange mode and has to be power cycled.
I have 5 Schiit products. I returned one. Their CS is terrible and it's nearly impossible to communicate with anyone besides AI. But their products are a great value and I haven't had any issues.
