Experience with Tannoy Westminster Royal Gold Reference

HDDG 10-14-2016
My preamp output impedance is 500 ohms, would an amp input of 10K ohms be fine??

The Coincident Statement Line Stage has transformer coupled outputs, and no capacitors in the signal path.  Therefore it will avoid the large rise in output impedance at deep bass frequencies that occurs in most tube preamps due to the use of a coupling capacitor at their outputs, which can result in the deep bass rolloff Dover referred to earlier if power amp input impedance is low.

However it is conceivable to me that other adverse sonic effects might occur, at least to a slight degree, if the CSLS is loaded with a low impedance such as the 10K input impedance of the Gryphon Mephisto Solo.  So I would suggest contacting Mr. Blume of Coincident and asking what minimum load impedance he would recommend for use with the CSLS.

Good luck.  Regards,

hddg, if you pick up the pair of Mephisto amps up FS on the ’Gon right now, you will do very well. They are great amps as I said & will sound great for many years to come. I just had to correct some apparent misconceptions about Vitus amps which I know are equally, if not even better engineered than the Gryphon amps & have equal merit depending on one’s tastes and equipment of course.

JF runs a business, and as you correctly pointed out, some reviewers ’get in bed’ with manufacturers for what I would describe as mutual back scratching. Nuff said. Enjoy the Gryphons!

I don't think it would be wise to spend lots of money on amplifiers for speakers that you are not sure you like. Here is a review on the Sophia Electric 300B amplifiers paired with a pair of the large Tannoy's. Not sure you could do much better for any price.

Very good advise from Al, i will put to practice and contact I.Blume to check out. If need be, i have another high end preamp that might be better (Esoteric Grandioso C1), could try that as well.
Jim, i do like those speakers, they sound great with my top notch SET amp outfitted with the famous and great sounding Takatsuki TA300B tubes, but they just don't have the stamina for complex musical pieces at a good volume for a large room. Simple as that. That's why i termed them as difficult speakers, they need absolutely everything, and primarily big watts of big quality.
Melbguy1, was going to take the ones on Audiogon, but big hassle and additional cost for transport and to change them to 230V, and no ways to use transformer, and warranty is not transferable. I prefer to get new ones with my deal from Europe for just a few more bucks.

I should have mentioned that I have used the Sophia Electric mono blocks with the Tannoy Kensington's. Sounded good to my ears. My ears are not as good as they were when I first got married. I could hear my wife call me from the second floor when I was in the basement. Not so much any more.
