Tannoy Westminister Royal SE Pre-amp Preference?

For thirty years, I have been a proponent of electro-static speakers. Six weeks ago, I acquire brand new Tannoy Westminister Royal SE speakers. My electronics have been tailored to electro-statics; powerful solid-state power amps (Classe Omega Omicron) with tube pre-amps (ARC REF 5). Now it seems low-power high-quality tube amp(s) are in order with the Westminister speakers. My question is simple (hmm ...): should I consider using a high-quality solid-state pre-amp with equally high-quality tube (Viva Auroa) power amps? Or, should I retain the ARC pre-amp for use with tube mono-blocks/amp?
