Tannoy Prestige Canterbury GR - Amp Recommendations

Folks,

I am considering buying these speakers and would like to hear some tube amp suggestions from the current owners of Tannoy speakers.  

Does anyone using the SUPERTWEETERS with their Tannoy’s? If yes, is it worth the improvements? 

My current system consist of ARC GS150 & REF6.  

I spoke to one of the current owner of Canterbury SE’s and he recommended Cary 805SE or 211FE and Mastersound 845 or 300B amps. 

Thank you for your feedback!
