I received my SW51+ unit a few days ago. First, as I told @Zampotech, it was remarkably well packaged and traveled intact from Russia to Colorado. Here are a few pictures to illustrate this... https://mega.nz/folder/3BwRyIJY#bGo4vGQ7_xS7F1JLoPpaNw End result: Not a single scuff or scratch, even though the corners of the box were quite worked up. Then, there is the quality of this amp. A lot has already been said and I don't feel competent enough to add anything that hasn't already been said. It's a great amp and I don't think you can do better for less than twice the price at least. So, thank you, @Zampotech, I will recommend you!
