I'm building an amp for a friend with more sensitive speakers, so my setup and ears aren't his. Hence the thread.
Bigger chokes seem to be a starting point so I looked up KGA, the Hammond importer in the UK. I had a shock to find prices in 2023 had more than doubled in one fell swoop. So Hammond is good value no more.
Looking for other UK winders who do chokes. Fortunately I have one or two as backups.
