Going to demo Quad L series - what else should I be trying? Booked for a demo session on Saturday morning. Im looking for speakers to complement a Marantz SR8500 amp. I like an open, airy sound, want to forget the speakers are there. Music takes priority over movies. Not interested in waking the dead with bass, the higher frequencies are very important, going to demo violin music to test this aspect. Your suggestions would be appreciated.
