If your speakers are a difficult load the Job amps may have a problem if not they will work fine. The biggest differences between them and their Goldmund branded conterparts, other than casework, is in the power supplies and the ability to deal with speakers like Wilson, ML, Raidho, etc. I have a friend that has had the Job Integrated since it first came out as his "back-up" and it has worked fine with Revel Studio II's, SF Strad's and big JBL's and though those speakers are up there in price they are not difficult loads. If you're looking in the "big dollar" category also look at Audia Flight and Trilogy.
