Current, Amperage



I’m trying to make sense of the argument about various types of speakers [ sensitivity, brand, etc ] and their relationship with power/ current/ amperage.

Can someone please provide some basic perspective.

I have a 91.5db tall floor speaker [ Focal Chorus 826V ] and what should I look for in an amp to drive these? How much power do I really need with all things being equal? I use a VTL tube 2.5 amp if that matters to the discussion.

Thank you.

The amperes/channel spec is basically meaningless along with most other ampere ratings. Current is a function of (ohm) load and will swing as the load varies across the frequency range. My rule of thumb is picking a reputable (voltage source) amp that doubles its power as the load is halved is usually a good starting point. Adding a class A design is icing on the top if the extra heat is not a concern. Current source amp tend to pair much better with (very) high efficiency single driver speakers, based on my albeit limited experience.
