While I really appreciate this thread from the standpoint of information, I'm more than a bit disheartened to read it.
The reason being, I'm getting together with some audio friends tomorrow to visit a couple of local dealerships, with my intent being to audition the 2805 and/or 2905. For the record, the previous two generations did not suit my tastes, and I've not as yet had the opportunity to hear the ESL57. I have no idea if this current iteration will work for me, as I've yet to hear them, but I'm more than curious at this point. I was going in with a completely open mind and the feeling that if they turned out to be the answer, I'd most likely move forward with a purchase. However, after reading this, even if I fell in love with them, I have truly serious reservations.
At any rate, having an intimate knowledge of some Chinese audio components, I'm not at all surprised regarding the issues regarding reliability and workmanship. Sadly, most of us see the things they do well (such as component weight and cosmetics - chassis, paint, etc.) and mistake that for solid engineering and build quality. I've learned the hard way the two categories are not at all intertwined.
