best loudspeakers for full Gryphon system

Hello,
I'm a new forumer: wander, from Italy (sorry in advance for my poor english...) . I'm going to buy new loudspeakers to be matched with a full Gryphon chain: Mikado CD player, Sonata Allegro preamplifier, Antileon Signature Stereo power amplifier.
Which loudspeakers do you think would be a good match? I listen to rock and classical music, the listening room is not too big: roughly
15 x 15 x 9 ft.
I'm looking at ProAc D80, Tannoy yorkminster, B&W 800D, Wilson Audio Sophia II... other suggestions?

many thanks!!

Wander
