I, like Illusion, use triphazers in my system, with very favorable results from a "tweak" such as this. As with all tweaks, UMMV depending on your system components, interconnects, speaker cables and condition of your AC source..etc. However what makes the triphazers very different from other tweaks are their extended "conditioning period (aka "break-in")necessary to experience the awesome impact that can be made to your system's sonics. I started experimenting with Triphazers about 14 months ago, and now use a 20.0 speaker triphazer with my Osborn Epitome spkrs, a 25.0 Power AC triphazer on my DAC (EVS Millenium II), a 2.0 line phazer between the output of my preamp (Wyetech Opal)and the input of my monoblocks (Denalis). I have just recently placed the power AC and line triphazers in my system and is right in the middle of "conditioning" my system with the new additions. I can give details of my experience (impact on frequencies, soundstage, separation, background, imaging..etc.) if the thread wish to hear such. As a one-liner summary I would say:The triphazers allows your system to fill the room with music, with a great presentation of acoustical space. The sound is taken from a forward, in-your-face type of presentation (for example) to one that is more musical, balanced, with a depth of field that increases your level of enjoyment. NOTE: We are talking about a level of change to your system due to a tweak. I was a non-believer until after I experienced results after a substantial conditioning period. If you have the patience for this type of system tweak, it's well worth the effort.
