No. To leary of opening up my speakers (Tektons, Vandersteen and Maggies) for that. Although my friends that have Tektons have done it and it certainly works! I have been experimenting with placing them on back plates of cd players right next to where power cords enter the unit. They are magnetized so they stick right on to the back plate. Also on top of DAC's and on top of interconnects coming out of DAC's. Still experimenting. Not sure of best application.I have no idea how or why they work but they do to my ears, seem to actually clarify things perhaps by lowering noise floor, making things seem more natural and open. Vocals seem to pop out in a natural but more detailed way unlike say a detailed cable that may be hard at the same time. Hard to explain and I know people are disgusted by these types of descriptions of tweaks like these. Wrote to Mr Bybee and asked about application and he said to experiment as well. My friend is getting great results by placing them in breaker box!
