I bought from both. The FO speakers all had flaws, but I had to look very hard to find them on all but one. The 600 had a vinyl overrun on a corner. Looked pretty bad, but a jeweler’s file took care of the problem and now it’s undetectable.

So, don’t buy them thinking you won’t find anything wrong, you may. It may be too much, but then again, you may not be able to find anything wrong at all.
