If the accurate reproduction of the music contained on discs is the goal, then the resonators should not be used in a system. I have no doubt that they can effect a system's sound, and for some people they might like the sonic change, but the arbitrary addition of metallic overtones is not a step forward in high fidelity sound reproduction.
In effect, the resonators are plate reverbs, but without any adjustability. If you really like this sort of processing effect, then why not get a Lexicon PCM91? It has dozens of different types of reverbs and spatial programs and massive adjustability. Virtually all audiophile would consider the Lexicon not suitable for high end systems, but that same judgement should also apply to the resonators.
