RossEvans…. Welcome to the forum. Which Tannoy’s are you looking to buy? Apart from how loud you like to listen to your music as Lin pointed, you have to remember that each of the Decware amps have a certain sonic signature. Some are more relaxed and others are more bold.
Also….how complex is the crossover network? While I am not certain, I thought that certain Decware amps do a better job of handling more complex crossovers than others, but Steve and others here will be able to tell you better.
EdGuy on this forum runs a pair of Tannoy Canterbury’s with his Torii MkIII. Here is a his YouTube video…

Good luck and keep us posted on your journey.
