I havent been following but you guys are installing firmwares from someone who just joined headfi? I guess the risk is less with the dx50 since it doesnt house any personal info like our smart phones but is the difference really noticeable that you would do that? I guess I dont have golden ears because I rather wait for something a little more official.
Well, like you say, the only risk is that the player would be bricked - there's no personal info on there to be stolen or anything, so a relatively minor risk. For me, the temptation to marry the SQ of earlier FWs with the stability of the current one was too great, so I decided to take the plunge and let everyone here know how I got on. As it was, it's fine.. no problems at all and I think it's worthwhile doing.
If I had a tube amp, i'd be tube rolling I guess.. I don't, so I'll have to stick with FW rolling instead - it's fun!
