Have had my Dali Zensor 1's for almost a year and a few months ago their sound changed quite noticeably. They're no longer as crisp as they used to sound and struggle when turned up to higher volumes as well as the bass sounding a lot less tight than it used to and a drop it treble too 
Is this normal or should I take them back to Richer Sounds? They have a 5 year warranty which surely covers them if they've deteriorated that quickly?
Appreciate any advice, thanks!
