Call me bias but I like watching anime in original un-dubbed format. There are WAY TOO MANY overused voices actors in America. >3<
imo
The reason you hear the same actors is because the most prominent company is the one licensing the most recent series. The ones that are advertised and most interesting will of course make it seem as if the actor pool is the same, but if you expand beyond Funimation you will see quite a lot. There is a notable slump of anime in North America though, and Funimation can't seem to hire other VAs due to contract reasons.
In Japan (for example) you have Ueda Kana and Seki Tomokazu who seems to be stuck doing the same role every season. If you watched a lot of series from one company, you will notice they hire the same voice actors quite a lot. And the most popular one, at whatever moment, will always get the lead role, ala Aya Hirano for instance.
In addition to both countries, there are people who claim they want to hear new VAs, but when one is gotten, they accuse the company of hiring "a nobody".
