Amplifier Recommendations to Match the Tannoy GRF90


Hi Everyone,

I previously posted a very similar post, but it was about the Tannoy Westminster GR, and it appears that since, I have become a Tannoy adept. I have a second system which sounds real good, but the Westminster GR are just stratospheric, so I have opted for another pair of Tannoy, and I got a real good deal for the GRF90. The thing is that I have never heard them, but I got a fairly good description from the agent which is a well reputed and trustworthy person. From what he says, they are in the Prestige line, but do not play at all like the Prestige speakers. They are built and sound more like the Kingdom Royal which is top of the line; very dynamic, with a more nuanced bass and especially a very transparent speaker. They are 95dB.

My idea of sound is simple; it needs to have everything done very well - resolution, tones, imaging, soundstage, scale, rythm/timing, balance, and I particularly love attack and dynamics, which to me are essential because they bring the music to life!

My gears are Esoteric P-01X and D-01X for transport & DAC, Masterclock is Esoteric G-01X, preamp is Coincident Statement Line Stage.

Now I am looking for the fantastic amps, must be monoblocks, that will make the GRF90 go to full potential!! So, thanks a lot in advance for sharing your knowledge, views and experience, especially if you have or know well about these GRF90.

Tunefully yours,

mulveling, thanks a lot for that input. I usely prefer SState because of dynamics and general handling of speakers. I heard about some hard mids on those GRF, and was wondering whether there wasn't a lack of break-in there. It is often the case. My Westminster were very much ear wrecking when new, and it took much much more hours than the few hours mentioned by Tannoy to get them tuned in. It seems that they are still improving to date. They are playing on Gryphon Mephisto monos, and it is just phenomenal in every way, never heard this level/quality of sound anywhere before. If I had the means, I would have gone for Gryphon Colosseum (Mephisto maybe too neutral for the GRF, although I also read that putting a very neutral amp like the Bryston 7B3 would be great to keep that neutrality), but no longer the budget for such amps. What would you think about the Coincident Dragon 211 MkII, they are 75W pure classA and have great low end.
Thanks blindjim, i share those views... and Pass is actually in my thoughts. Tubes are nice, and i own some nice ones, but I've come back on them, except for smaller applications. In reliability, power, dynamics, attack, bass control, all versus their cost and put up against serious and well built SS, they seem to lose the battle, especially for bigger speakers and rooms.
Hi charles1dad,

Funny!! I actually own all the amps you are talking about, and i will be trying the Dragon on the Tannoy for sure. But I am in a tropical region and summer with big PP 211 tubes is just very sweaty. Moreover, i have tried those on the Westminster GR (99dB!!!), they were doing actually well, but i’m a real difficult guy when it comes to sound, and thought that they did not have full dynamic control and did not completely seperate instruments, especially bass at higher level. So i am suspecting they wont fully satisfy me with the GRF, along with the heat issue. I must admit that the Coincident products generally have great sound when they are working properly. But I’ve had a lot of "bad luck" with them for just about every single thing i bought there, although I kept renewing my trust to I.Blume, but susbequent orders kept coming with issues, and it was never his fault, always the transport or something else, and he would never make up for it, unless I argued strongly with him. I have conculded that there is some serious quality control problems at CST, and with the assembly/mounting of gears at the workshop. His attitude has been unacceptable, and I have decided to end all relations with CST. Just recenlty with the preamp, less than 2yrs old, the right hand side volume has come off from inside. I am sure (and hope) it is easy to repair, but this should not happen and does not happen with other gear at that price.
Hi charles1dad,
CST products sound real good, that's actually why despite several first issues which i decided to put aside on bad luck's account, I kept purchasing products from them for my various applications, but now enough with "bad luck". Still using some of them, and will someday get them all upgraded/serviced by some tube specialist. The Franks work great, rolling Psvane WE300B and incredible Takatsuki TA300B.
Thanks for your wishes,
Best,
Hello everyone, thanks for all your help so far.
  
I wanted to share the last developments on my side and get your advice and thoughts about it. I have just received a very good offer/opportunity for a pair of Pass XA.8. Why a pair will you ask since these are stereo amps. Actually, my thoughts are to use them as monos and vertical bi-amp the GRF. I have not heard these amps, but heard and read only very good evaluations about them.

What do ya think?  
mulveling, i totally agree with you about Tannoy, and that’s also part of the reason i chose the Westminster GR. But still, despite the high efficiency, I have put very powerful amps on them (Tannoy give a hint about that in their manual). So many Westminster are being played with real small and unpowerful tubes, surely sounding very nice to a certain point, but i believe these owners do not even guess or will probably never know the full potential of those, which is enornous.
