I have bought many China electronics. I have learned to use Google chrome translation on the China Taobao site and other Chinese reviews. There are cheap knockoffs and there are VERY good ones. Unless you know the language or spend time on the Chinese language sites you may never know. For the most part the ones on Aliexpress are the better ones but the best ones are only on the Chinese language Taobao.
I have very high end original equipment and some of the best clones. The best clones sound incredible but are slightly different from the exact sound of the originals. Unfortunately there are some real turds as well as outstanding products as well. Most are modeled after discontinued products though which probably circumvents the issue with copyright. The Dart Zeel boards are 100% exact circuitboards and the component choice and device matching it what will seperate the original sond from the clone in absolute terms.
