Hello, I bought my N8 in 2008 after demoing most of the top daps. My main focus was sound. This wasnt my first round of searching for "the dap", way back in 2006, I bought what was back then the top dap. I bought: Cowon, iAudio, Creative, Colorfly, Hifiman, and an Apple player. Then bought the iBasso DX100 , another Cowon , the the newer upgraded A&K daps like the 100 , 120 , and so on. Well since buying the N8 I bought daps that I demoed months before inorder to make sure Ill still like the N8. I bought a new A&K, a 3,000 USD dap, a new Colorfly dap, a new Cowon dap, a new dap that can play music from the internet etc. Well I ended up selling most of them. Why did I sell them ? Cause the N8 still sounds better to me. The N8 sounds better at home where its quiet and sounds great outside where its crowded and very loud. Interesting that I noticed many of the top daps do sounds great when the enviroment is quiet but stop sounding great when the enviroment gets noisy. I am curious if Cayin could make a top portable amp ? Im using headphones and I do enjoy using a portable amp.
