A couple of years ago I inquired with a dealer who had a used Line Magnetic amp listed on his website (he otherwise did not carry the LM brand). He tried to discourage me from buying his listed amp and stated the following in an email back to me:
In my opinion and my experience, the gear out of China is inferior and we had way too many technical issues. The sound performance is also disappointing. We recommend that you buy USA, European or Japanese, Only.
I wonder if we are all talking about the same dealer here? These comments were completely off-putting and I ended up purchasing a brand new LM805ia from an authorized dealer. The LM has been flawless and is my favorite amp in my stable by a long margin.
