With Decwares backlog and current economy all workable inventory is a go from my perspective. If a defect like that is noticed after wiring when turning the amp over it would be very hard and time consuming to replace that cosmetic defect. In a material starved world the nitpick rejection of receivables is out of the question. IMO.
Not sure the process at Decware but would hope that each artesian involvement in the process of building the piece would start with selection of parts thru running preliminary tests. Again in a material starved economy and backlog some slack must be given for cosmetics.
I have built several of Decware's pieces as well as bought many from previous owners. All have had some little 'defect'. Some were caused by the previous owner and some were obvious built and shipped that way. But, all ended up working as Steve describes in the owner manuals and colorfully here on the forum.
