- We're audio and music enthusiasts like yourself. We aren't in the business; we're amateurs interested in getting the most out of our systems and enjoying the music to max! There's no commercial pressure, just fun with friends!
- We have fun listening to records and CDs other members bring to meetings, to find out what are some of the hot recordings--both in terms of musical performance and sound quality. What kind of music makes you want to nod your head, tap your toes, wave your arms, sing along, or get up and dance?
- We like to share cheap tweaks as well as those which aren't so cheap, all in the search for sound which stirs and satisfies the soul. Each person may have a different opinion about what makes good sound, yet we understand measurements have some relevance. We try to learn about the science behind audio and recording in addition to the art.
