The trouble with the Mini-M8 is that there hasnt been enough reviews or impressions as of yet.
One or two people have shared their impressions of the Mini-M8 and some have reported hiss, this is far from conclusive.
Usually the first impressions/reviews are what people remember - whether on not they are accurate or true for most of the users.
We havent enough information of what kind of source they were using, their files, the headphones etc.
When I tried it at an audio show I had no problems with it. I am reserving my final thoughts for when it actually in my hands.
I will try it with different players, different cables, different types of music files, I will use my different headphones and also take it to a store where I can sample 100s of in ears If needed. I will also test at one day, one week, one month to see If there are any changes.
If its a dud or there are any issues I will share them, regardless of my love for Centrance products.

As for the Skyn, as a company Centrance do have to promote their product. Although in this instance I think its more a case of Centrance gathering information from users in the same way they did with their Hifi-M8 (for better or worse, I like to think of the Mini-M8 as the final refined product of the Hifi-M8) to improve the product to better serve user wants and needs.
There are a few flag wavers and kool aid drinkers on the Skyn thread, which isnt Centrances fault.
Mini-M8 didnt get enough promotion I think, perhaps its the current saturation of the portable dac/amp market. Although its a great all in one device with many inputs.
