I currently have an X3/1 which i love. I did buy an X3/2 but didn't like it. The first gen. is bassier and that is a deal breaker with me, the bass. I imagine i like the sound of the first gen. because of the Wolfsen DAC? Is it used in any other FiiO player? Also i didn't like the fact the 2nd gen. didn't have bass and treble controls. The equalizer is good but i find having the seperate bass/treble controls a bonus. I use my player with an E5. Which generation of the X5 is bassier? I've read some people complaining about the first generation's wheel, is it a major concern? Are there bass/treble controls with any of the X5s?[got a feeling there won't be!] Which generation of the X5 has the better sound quality? Thanks.
