Normally, I don't pay any attention to what reviewers say, but the one you quote may be relevant. Your 11a is a very laid back component. If the ET3 is similar in sonic character, it really may be too much of a good thing. The 17 may be a better option if you don't want to go too far in one direction.
As far as looking to another brand, ARC or otherwise, I don't think you have to. CJ's preamps are outstanding overall. I've owned several and still have a Premier 18. Its SS and wouldn't hesitate to recommend that, as well.
