What I find very interesting about Tannoy speakers are the wide range of amplifiers used by their owners. From 300b SET to 300 watt solid state or class D. They all seem quite satisfied with their respective choices. Of course numerous variables will influence one’s preference.
That is why I said with regard to the OP, what type of sound is he seeking? I also know that even with the same speaker sensitivity, they all aren’t equally driven due to other factors. My speakers are 94db and just sing with 8 watt SET (Preferred over my 100watt PP tube amplifier). However, circumstances do vary among listeners.
The NAT Audio amplifiers have a reputation for exceptionally good power supply design and their own hand wired transformers. For my taste it’d be the NAT Single HPS. No doubt others would make different choices. Which is attested to by the diversity of amplifiers used among Tannoy owners. Many good options.
