I'm not familiar with the Arundels, but Tannoys work well with a wide range of amplifiers. I'm using two polar opposites currently, a 9 Wpc SET 300B, and two Class D Audio CDA 254 amps bridged to mono, @500 Watts into 8 Ohms.
There are some very highly regarded pairings of Tannoy/Luxman, some Luxmans more so than others. I recommend you Google Hans Hilberink's Tannoy website, much information regarding this pairing can be found there.
Regards, and enjoy,
Dan
