Yes I agree GigaWatt PC3 SE EVO is beautifully built, relatively light weight and easy to use. Torus bigger Power Isolation Transformer are big (very deep) and heavy.
I use my GigaWatt PC3 SE EVO only for my audio gear and one Oehlbach - XXL Powerstation 909 for my computer. I like to keep them separated and think that it’s important to prevent one audio gear to infect another audio gear, as interference generated by one devices in an audio system can have vary serious effect on the sound. Some people clam that all audio gear should be used in one distribution list. I have tried it and it was no good (for me). A simple isolation transformation is not going to keep noise generated within the system from pollute other gear and make all kinds of leaks and ground loops. My Gigawatt has 6 outlets in 3 independent filtering branches, separated for each pair of output sockets. I need 4 independent filtering branches as I don’t want to have my streamer and DAC at the same branch as the computer or amp. I have tried.
I like my Gigawatt especially together with Powerstation 909. I’m sure that I would be just as happy with some other of the TOTAL mains power cleaners. PS Audio P10 is great as is Torus Power and Audience new stuff.
A PP like Gigawatt improve sound by take away noise. Less noise increase every audio aspect, IE better dynamic, superior clarity, improved image and definition, better bass punch, deeper bass, bigger and deeper soundstage, truer colours, richer mids, better coherence, more engaging and less fatigue sound. Good quality mains power is the most important thing IMO. In reports from shows you can often read things like the room was no good, and yes for speakers the room is essential, but equally essential is to feed clean power. Many manufacturer seems to neglect it then showing there 100 000 speaker system that sound like crap.
I have heard many of the more well-known mains power gear (not all), but not in the same system, so I cannot say exactly how one sound compared to another (and I believe what’s best in one household is not necessarily the best in another, on this near SOTA level we are talking about). I can only say which system that sounded good or not. People like Leif Mårten of Martin Audio have the time and resources to test them all, and probably have. If they choose Gigawatt to be used in their super system (that sound so great) its fine for me and my more modest setup. In some cases I have tried two PP or regenerators in the same system (mostly mid-priced PP and PG) but it’s a really difficult task to do as we need to put everything in correct phase, right filter branch and to wait for all device to warm up again, no quick A/B comparison. Very time consuming and hard to do in system that I don’t know very well.
I will and my discussion on this topic for now, but please report after you got your mains power cleaner. Am sure it going to lift your system sound to new heights.
