After a month of agonizing customs and shipping problems I finally was able to get Martin’s S9 over to him. He couldn’t be more pleased sighting the brilliant screen and native video support. With that as our trusted headphone editor he has performed listening and RMAA comparison tests side by side with the Cowon O2 and D2.
While I didn’t buy in the hype of being the best sounding Cowon to date (check out my S9 review), he didn’t either- though stating it is nearly the same as the recent Cowon players. Check out the details and frequency response graphs comparing the S9 to the O2 and D2.
