No problem to insert the cables into the banana plugs, which fit perfectly in all my terminal blocks (by cons, do not be afraid to push, there are obviously some resistance due to the effect of "spring" produced by strips ... but, rest assured, no problem to remove them!)
By cons, they are not lockable (as some more expensive models, such Audiophonics), which can cause problems on a smaller section cables. In this case, it will insert the side hole banana plugs.
Otherwise, no significant difference in the ear before and after the installation of Banana Plugs (before the cables were just twisted and directly inserted into my terminals). Good product, then! :)
