Hey, I have a Job too and am pretty happy with it. Also, it's true the Maggie's would be a hard load, and he admitted he wasn't able to do an apples to apples comparison with the others due to grounding/noise issues with DAC direct. He also admitted he needs to do more listening and will be doing a more thorough follow up. It was also clearly the most inexpensive amp in the comparison by a wide margin and held its own in some ways, even in an unfair speaker matching. I think I recall that he has Devore Orangutan speakers, and I'd be really curious about that pairing.
All that said, I could see his point that speed might be the Job's biggest strength, and not as much tone density. In my own system, I run a different model of Tekton speaker and get my tone from a fine tube preamp and an analog sounding NOS DAC.
In my opinion, the Job doesn't have to be universally perfect to still be a grand bargain. And what it does well it does really well. I just get tired with the back and forth on forums of best amp ever vs. hyped up flawed design. Seems worth characterizing the Job's strengths and letting people know about some ares that aren't quite as strong so they can make educated choices about whether to try it or what other components might help complement its character.
