mmm......let's just agree to disagree and move on. Whether you believe the cu is better than the rest or not is immaterial. Some will say it is, Some will say it isn't. It is a zero sum game since none of us here knows how many cu units iRiver has sold since launch. Did it outsell comparable DAPs in the market? Did it outsell the previous AK flagship? Did it sell all 500 units of the cu? In other words, how did the market vote with their wallet?
I do agree with @louisarmstrong that the 380 cu is the best of the best of the best, in terms of SQ in the (unmodified/stock) DAP market. The only real competitor is the AK 380. If you look at the DAP market and setting aside the price tags, there isn't any finer. Not the Sonys. Not the iBasso. Not the Cayins. Not the Fiios. Not the Luxury and Precision. Of the DAPs, I've auditioned or owned, the only non-AK DAP that comes close in terms of SQ would be the super-ugly Lotoo Paw Gold and the qualitative difference is not even close. If given a free gift from Santa Claus, I bet you that 9 out of 10 headfier would choose the cu.
A large part of the dislike for the AK players is due the huge price tag. I can understand that and I do agree that iRiver is dangerously close to pricing itself out of the market, specially if its competitors step up their game in the luxury DAP segment.
I am not trying to persuade anyone here to get the cu. I don't care if iRiver sells 10 or 10,000. That's not my problem. I am just being honest as a headfier would really fancies high-end DAPs.
