I ordered these to remake my cartridge leads for a Dual 1229 table. These were very easy to work with and look great. The clips have a nice design that allows you to quickly solder the lead cables in place. very satisfied with my purchase. I can't say if they make the sound any better (currently re-cabling my tone arm as well) but I know I am much more confident that I am getting good contact and these clips will last a long time.
