Demonstrations at a HiFi Store are limited to the equipment of interest in a certain Price Bracket.
It is best to bring a owned item along wanting to be exchanged if this is practical and acceptable.
Demonstrations of equipment are not only limited to a Dealership Premises.
Sharing musical encounters with likeminded friends who are creating a HiFi System works, Being a Forum Member and using arranged events, as well as being a Local HiFi Club member has created many friendships and has got me access to numerous demonstrations of a variety of equipment, with no need to appear as interested customer.
Some of the equipment I use today and am totally wed to, are a result of meeting like-minded friends, meeting individuals presenting their equipment at a Forum Event or the Membership/Interaction with the HiFi Club.
