I ignored some of the scepticism I've read about Schiit and picked up the Jot 2 + 4490 combo while it's on run-out and... man do I regret it.
The amp stage is really nice, but the DAC has a huge ground hum if anything is using it, and worse yet, just having something connected causes the hum to come through when the source is the RCA or XLR, as well. I'm bemused how their QA could have let that ship.
What's worse is that to get it looked at, I'm shipping it internationally, which is costing me close to $300 on top of the purchase price.
A really, really lousy experience, and the promise of "good at an affordable price" has turned into "faulty at an astronomical price". Perhaps they're a great buy if you're in the mainland US, but I would recommend you stay well away otherwise.
