That's not really something any of us can answer. A lot of this hobby deals with ego and the rush one gets from buying tke latest and greatest audio jewelry just because one wants it.
I'd say that if you can hear a difference, and feel you can justify the cost for that difference, and you can afford it, and you want it, then I'd say go for it, If you say "no" to any one of those for questions, then I would forgo it.
Make sure you can return it if you decide to try it.
