”what does sound have to do with anything, i was talking about the build quality”

This comment might be construed by some as a bit of a disconnect. I’m not trying to be inconsiderate but how can you possibly make a determination on build quality? You haven’t heard the dacs you mention and you are passing judgement on build quality based on internet photos or the opinions of others on the net? Are you saying dacs made only of milled aluminum cases can be good?

Read all the different Amazon Topping listings with a 1 rating and you will see exactly what I said. That’s all. I was going to order one, but decided against it. From units buzzing, not working as they should, DOA etc....it’s all there.  One listing here....

Virtually all the bad 13 reviews you reference are from 2013 - 2107 with but 1 in 2018.....I had forgotten but researched it again the D%) as currently sold was released in March of 2018.....thus all the 2013, 2014 201 etc reviews that bother you are NOT relevant to this current unit....have a good day anyway.....  http://www.tpdz.net/news_detail/newsId=79.html
