Well, I've read trough the comments and quite sincerely, I's great if the current owners enjoy what they got, but the thing is, most people will use it for the USB input so it's a non issue, in my case I have zero need for a USB DAC, I only need optical and coax. But before throwing rock at the unsatisfied, the thing is, topping do read forums like that, it does hurt them and the good news is, they will definitely check the polarity before launching a new product, so as a whole, the audiophile community wins. It's relevent because it is one of the purpose of a forum likethis one. To push manufacturers to up their game. You are allowed to not care, but we certainly should be allowed to care. Most people won't notice any difference if the SINAD is 95 vs if the Sinad is 115, but still, the 95 one will not get more love here and will even get a stamp of "not reccomended" Don't buy this. I feel like something objectively measurable, audible in some specific conditions of music content, should not be swept away as just complaining and bashing, and unproductive. I find quite the opposite and personally would really love to see a polarity check in the list of measurments published here. Why not? I don't want to denigrate Topping as a compagny and will let them deal with this the way they see fit, but I, for one, am happythat I read about it here, that I have been to cancel my order, so it's informative and relevent for me. I'm sure that as is, it's still a great product for the price, just not a product I want. I would have like to have been able to get such a promising little DAC for so little, but in this case, unfortunately, this set of measurments don't tell the whole story, it shows that some corners have been cut, and it is to be expected, there is no free lunch and it's very cheap. Now I just need to decide on something else (suggestions?) or I'll order this in a heart beat if we get confirmation that the spdifs in have the proper polarity.
