The Luxman 550 is great with these speakers. It is class 'A' so it runs hot. Do not be put out by the class 'A' power output (20 w/Ch). I had the AX version driving Turnberry SE's. If you don't like the heat, the 505 or the 507 may fit the bill. The Luxmans have excellent high's that I have found hard to beat, are very detailed while remaining neutral to warmish, good bass and timing. There is a model a ii on Audiogon currently - they often come up for good prices used. The Primaluna integrateds are also very nice with Tannoy, although I preferred the additional amount of detail that you get when you use their separates. If you got Primaluna, the 40 w/ch amps should be all you needed with the Tannoys.
