Alan, since the "Cable Cooker" uses a switching power supply, isn't it possible that this could become a source of both EMI and RFI ??? It is well known that switching supplies are notoriously "dirty" due to the spikes and glitches that they generate when turning off and on continually. Have you taken steps towards filtering and shielding the pollution that this design is capable of ? It would be a shame to spend HUNDREDS of dollars on a product that actually added more intereference into the electrical system of the house.
As to the total cost of such a device, wouldn't it have made MUCH more sense to use common low cost devices such as IC's to get the job done ??? I see NO technical benefits to using discrete devices in a "burner". Since we will not be listening to anything through it, something that can generate and amplify the basic signal with good reliability, ease of production and lowest manufacturing costs would seem to be the best route to take in a device like this. While discrete components might sound good in terms of advertising, the burner is there simply to "pre-condition" the cables, NOT become another active component in our systems.
Also, since we seem to have your attention, what type of signal does the cable cooker produce ? Is it a sine wave, square wave, sawtooth, etc ??? Is it centered on one specific frequency, does it do rolling sweeps or is it simply a broadband "hash" like pink or white noise ? Is the signal constant in amplitude or is it ramped up and down ? What is the amplitude of the signal being used ??? All of these are things that will vary the effectiveness of this device. Needless to say, i'm quite curious about it and i'm sure others are too.
