Tweaks in High-End Audio are invariably controversial. Mind you, I am extremely cynical when it comes to high-end audio tweaks. However, as I have traversed along this high-end audio journey, I have found a few that have enhanced the sonic presentation of my system. This review is for one of those "FEW" tweaks that enhances my sonic presentation: The IsoClean RCA Caps and AC Outlet CAPS. These products give the musical presentation from your high-end system greater "Coherence".
Coherence is defined as follows: a : systematic or logical connection or consistency, b : integration of diverse elements, relationships, or values. Eliminating the stray RFI/EMI contamination that can enter your system via your unused RCA inputs/outputs results in a noise floor that is non-existent. Consequently, this brings out more musical elements that the stray EMI/RFI contamination masks. These additional musical elements raise the bar in Dynamics, Tonality and Harmonic Texturing of the the recorded event.
This tonal, harmonic and dynamics accretion from the elimination of the stray EMI/RFI, takes the musical beauty of the recorded presentation to a much higher level and allows you to delve much deeper into the recorded event rendering an even greater emotional connection. The musical tapestry becomes more complete, more relaxed, less constrained, and more logical with the additional integration of the musical elements that were previously absent or subdued.
IsoClean RCA Caps are made from solid, high-quality copper and have a removable center pin (see note below) on the end to fully protect your system from airborne noise. These are the best caps currently available. Highly recommended! NOTE: The IsoClean RCA Caps have a special Center Pin which helps prevent RFI/EMI contamination. If you are placing these RCA Caps on any OUTPUT RCA jacks – YOU MUST REMOVE THE CENTER PIN. You can use the pin on any INPUTS without any risk.
