I think you may have missed my point Kiddman, I was simply saying the S5's are transparent and revealing of upstream equipment, therefore time should be taken auditioning different amps to see what has good synergy to your ears. Obviously most good ESL's, ribbon or quasi ribbon speakers would have an edge in transparency over a dynamic speaker, but that is only one aspect of it's sound. Tone, timbre, smoothness, balance/coherency, imaging & the ability to scale and realistically convey the full impact of an orchestra (without the need for a sub) are important considerations also.
In general, fast, smooth, tube-like amps sound best with Magico imho. I've had great success running a Vitus amp in Class a which suits my tastes.
