The second half of the music session is designed to help you evaluate the system with music that you are familiar with. All members and guests are welcome to offer music to share with us all. For this meeting you may bring some music via USB or CD playable on the club’s Reavon player or request to stream a track.
All we ask is that the music and recordings be interesting. We'll ask you to tell us a little about the artist/recording before it is played. Tracks over 5 minutes will be faded out, to give everyone a fair go.
Whether you are a novice or a seasoned veteran, you will have the opportunity to listen, learn and share your experiences with others. Feel free to come and hear the capabilities of the system, or to just share the experience with like-minded music lovers in a friendly and relaxed atmosphere.
Venue: Mathews Room, Epping Creative Centre, Dence Park
Address: 26 Stanley Road, Epping
When: Sunday 9th August 2026
NOTE: It is a requirement of entry to the Epping Creative Centre that everyone sign-in to the visitors’ book upon arrival.
Hope to see you there on Sunday.
