I think a problem with her voice may come from the quality of speakers,usally if you have a good set up with base, then you can get more of how it would of sounded there. Its like complaining about techno songs after hearing them on pc speakers. You need good speakers to get the best from ayus music tv live
and no LQ versions of things. But it could also be ayus heart isn't in her tv lives anymore, she may just do them to get it out of the way. Her hearts in her tours and concerts and they sound good, from a-nation to her team ayu tours. And she's not promoting a new song so her tv preformance isn't selling a new single, so no matter how much she could spend and new outfits, it would be a loss in profits. She may be ayu, but music is a money making business. Also ayu can easily pull of the grand gowns so why not, not everyone can pull that look off good.
