What is the best amplifier for Tannoy Kensington ?

Thanks for the advice. Once I heard the Turnberry with ATM3 and with ATM1 S. The last was more musical. Maybe less tubes, so less components, cables and solders on the signal path leads to better transparency and a better direct contact with musicians...

I've upgraded to VAC 200iQ monos on my Canterbury GR. They sound phenomenal. Tannoy and VAC is a great combination! 15 Watts on Tannoys isn't enough for me. 80 Watts is ample. 

Unfortunately VAC is not in my price range. I think I will keep the ATM3s for now and wait for a used ATM1 (not S because I prefer tube rectification).
