Vortex HiFi | Power Cap | Sigma
- Product Review (submitted on May 26, 2022):
- Following the advice from Ron Kemp, I installed six Power Caps Sigma in wall outlets surrounding the listening position. So not in the power blocks of the big stereo system, but at the power plugs of lamps and such. To my amasument, the effect on the sound was heard immediately, most clearly when listening to piano solo. A better articulated sound emerged, allowing one to hear small ornamentations much better. Also the more refined timbre was obvious, characteristic of the particular instrument. It’s a miracle really … . The effects are certainly comparable to what a real audio tweak costing much more can do for the sound … .
