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!!

i suggest that Gryphon would be great match with;

Avalon.
Sonus Faber.
Verity.
Rockport.

i'm not so impressed with Gryphon CD and preamps. i would not want a full Gryphon gear myself, but the classA poweramps are special if partnered rightly.
hmm i experience a full Gryphon rig as a bit to the technically perfect side. it is very impressive on it's own terms, but personally i would choose speakers like Sonus Faber or Verity to bring the touch and soul and the music. partnering with Gryphon poweramps will likely give nice balance :-)
Agree 100% with Tuboo. 15x15x9 would have significant bass issues with speakers with extended bass response.
The Cantata is a sealed system using a Q controller and will help you bass issues in the small square room.
