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

Hddg, that does sound like a good deal on the Gryphon Mephisto mono's. And no question they are great amps. Though I don't agree the Mephisto mono's are a grade superior to Gryphon. I can tell you, Vitus's factory is SOTA, and arguably superior to even Boulder. Virus designs his gear to achieve a sound which offers the best of SS, Class A, zero NFB design, with a natural/organic tube-like quality. He also designs his amps to be non-fatiguing. 

Fyi, Vitus will be releasing new SM-103 mono's, probably by early next year based on the SS-103 stereo amp which should be around $60kEUR. Like the SS-103, they will operate in pure Class A with Zero NFB & feature Intelligent Class A bias' & two tunable modes 'Classic' and 'Rock'. They will absolutely compete with the Gryphon amps on any metric. Though I wouldn't pair Vitus monos with a tube preamp. Rule of thumb: Vitus sounds best with Vitus. Sound-wise, I think you'd find Vitus sounds more organic and tube-like compared to Gryphon, but still with PLENTY on control, speed and resolution. Just with a more natural presentation. Just another option to consider...
In an earlier post on this thread I think hddg indicated that he's not looking to spend that kind of $$$$$.
There has been good feedback using Sophia Electric 300B amplifiers. The life they bring to the speakers is in the midrange.

According to XE.com, $60,000 USD = €54,511.64EUR, so he is not far off the mark. Also, Vitus is made in Denmark so he would be able to access better pricing than in the US. Besides that, personally given the choice I would prefer to own a Vitus SS-103 & SL-103 preamp over the Gryphon Mephisto solo & Pandora pre. But in the end, this is all subjective.
