Not sure how a 'reclocker' works but I have just added an 'external' very high quality clock to my digital system. This does not 'reclock' the signal, but presents an external timing reference to the component. The component was a dCS Network Bridge.
The impact was magic.
The bigger 'magic' (by orders of magnitude) was upgrading the clock cable from the basic one that was supplied - this is not necessarily expensive. Caelin Gabriel (owner Shunyata) advises the jitter removal from this action is what brings digital into analog territory. I can only agree.
Best wishes
