Indeed, the ElectraClears are an amazing bargain. I have several distributed around my system and home, and there is a fullness and dynamism to the sound that is quite satisfying, whether the source is digital or analog, Even the OLED picture shows a startling improvement.
Even the wi-fi appears to be faster! Does anyone else notice the improvement to your computer image or wi-fi?

Also, the Symphony Pro adds another level of sonic tonic!

Yes, i have an ElectraClear plugged in where both my modem and router is and I definitely got not only an increase in clarity and presence on my stereo but also my tv picture where I stream movies from my Apple TV. 

How would you rate the increase performance of the Symphony Pro versus an ElectraClear?

Does anyone have experience with the "Wizard" unit? What does it do and how does it perform in comparison to Electraclears, Symphony Pro, and Sorcer units? What are the dimensions of it?

@t_ramey    Sorry for the delay to reply.
Question: So you think that the ElectraClear is improving the performance of your computer, i.e. speed? Maybe that would also account for an improved image and streaming experience?
If the processor speed increases then ....whoa! wow! certainly stop the presses news! Eh?
The Symphony Pro definitely does a fine thing to improve tonality in the music - night and day increase in transparency, as well as big time increase in the sound stage. ElectraClear has a nice warnth and fullness, ala tube, plus it creates a fullness to the sound. Yes, punchy, articulate, solid, dimensional. Carity and presence also improved. 
i can continue with more adjectives, so I'll stop.
Together they are a no brainer -
I even hear a wonderful improvement to the radio in a Panasonic boom box, driving a pair of small Dyne audio speakers used in the RS Optimus line (from a long time ago.)!

@yoby : The Wizard does what the Sorcer does but just not with as much "in your face" attention or urgency. It makes the presentation more relaxed and smoother. Placed near the digital or pre-amp front end is the best location. It extracts detail and nuance that is buried in the digital signal. Amazing!
It is a modest 13 x 11.5 x 1.5".
It gives more of what the Sym Pro and Electra Clear are doing - harmonizing / tuning the system (with the antenna coils I suspect) plus inserting harmonics onto the AC line in such a way as to resonate the entire music signal. Sort of like a real time tone control but without any of the phasing artifacts!
