Beautiful sound was the order of the day at Tone of Music Audio (1303 Castro Street, Suite D, San Francisco, CA 94114), as the small retailer, headquartered in the heart of San Francisco's Noe Valley, held the first of two spring open houses. Judging from what the 30 or so visitors heard at the first open house, on March 18, those who show up for the second listening session on Saturday, April 1, between noon and 5 pm (RSVP to info@toneofmusic.com), are in for a treat.
