Hi,

It will make a more mechanically and electrically secure connection, but you won't hear any difference, unless the old guillotine connector is intermittent (you'd hear static-like sounds if you wiggle the wire in the connector). The spring-loaded connectors can gradually deteriorate or slice off fine strands of bare wire, which can make a connection poor or intermittent.

Binding posts, especially gold-plated ones, won't oxidize or corrode over the long term.
