Experience with Tannoy Westminster Royal Gold Reference


I own these great looking speakers for a few months, and i am looking for views on its sound quality and people who have long experienced these speakers with different amps, electronics, and rooms, etc..
Based on my short experience, it seems that they are very easy on power quantity as being very efficient speakers, but require absolute quality watts to sound their best.
It feels as if they have infinite potential for sound quality and power, as long as you have what it takes to feed them, so how far can i, should i go with these in terms of associated equipment?
I hope that experienced audiophiles out there can help me realize the full potential on these beauties.
Thanks

"...As a preamble to those reviews, let me just say that the synergy between ASR and the Tannoy Kingdom Royals reported to me by listeners from around the world is quite real, and if there are Kingdom Royals in your future, you might as well starting writing the check now for the ASR electronics, as they are a superb match..."
Yes, they are indeed!!
For the sake of the discussion, I am actually using Esoteric Grandioso P1 & D1 as source and DAC with G1 masterclock, Coincident Statement Linestage for preamp with WE101D Psvane tubes, amps are Coincident Dragon 211PP MkII monoblocks with upgraded caps and WE211 Psvane tubes, and cabling is Tellurium top line Silver Diamond. I forgot to mention that the Tannoy are complemented by the Prestige supertweeter. The sound is very good, but i would like it to be absolutely great, and I think the element to improve is the amps. So any experience out there is welcome!!
