Eye-watering price for what it does.. Some people already have balanced power, I know I do right from the supply. 115 and 115 out of phase

It´s basically a transformer in a box.

Thanks for the information, guys. It’s what keeps me coming back to this forum. After reading your comments, I’m rethinking the value proposition of the EquiTech product.

Rap, are you saying that your power is balanced at the panel, so that your whole house is getting balanced power to all your appliances? If so, that sounds like a new construction installation. (I bet it also sounds like heaven).

CAJ, thanks for the explanation. I knew a little bit of what you wrote, but not all. I have a couple of isolation transformers, but they must not be balanced, as they have a helluva hum. I use them as glorified extensions cords in the garage where noise doesn’t matter. Can you share what brand balanced transformer you use? Is it quiet?

Crazy Bill, what an interesting company! Thanks for sharing. i wonder if anyone has tried the Goertz speaker cables.

Bottlehead,

We have 3 phase into the house and it´s broken down from the panel into 2 phase where 2 wires are live and one is the neutral out of the three. The fuse box carries double breakers one for each line of live wire and they measure 115v each for a total of 230v which is code here in Iceland. I´m not an electrician so not sure how they convert 3 to 2 maybe they use some form of Scott-t transformers.

Electricity is generally good here but think that might be more because we dont use those pole-transformers outside the houses. I use a powerstrip with ferrite beads in it for the hifi but not sure I need it though it should filter out high-frequency noise from the line if any.

Hope you find a good solution that doesn´t cost an arm and a leg...

p.s As to "a new construction installation" I gather it´s actually an obsolete style of power distribution, it´s in a lot of the older houses here in Reykjavik...

This may be what CAJames is talking about... not the thing I typically used to think of as an isolation transformer... like those triplite types that hum.

I got mine from a Chinese seller off aliexpress, so can't comment on this seller, but this looks like the one I have. It sounded fine when I got it. Then I upgraded the fuse, and by sound, the caps across the AC receptacles (with bypass caps), and maybe something else in there... can't recall... but it sounds quite good to me.

Yes it is a nice unit, clearly made for audio, with a pretty heavy aluminum case, OFC custom wound transformer, gold plated copper IEC, mine either had pure copper receptacles or gold plated copper, low key cap filtering, etc... this one anyway, just seems nicely designed and made.

I am glad you got on a good trail with toroid.com. I look forward to hearing about what you come up with finally, and listening impressions! Power is a real trick to me, inside components and feeding them, every choice seems audible. Makes me wonder what a signal path really is functionally in resolving system/rooms. Well we know what we call a signal path, but to me, it seems the power feeding that path is just as important in the big picture.

Sounds intersting. Seems a lot of folks really like Puritan. I would love to hear them.

Right now I am running in four stages, 1st a Mapleshade receptacle, then, all modified with better parts by sound... The Chinese made balanced transformer, followed by a Pi Uber, followed by an Audio Brickwall.

There is a Furutech filter plugged into the Uber, and a Shunyata filter plugged into the Brickwall.

All nice sounding cables, two DIY, and one Chinese made UPOCC copper with UPOCC gold plated copper ends. In the beginning, the power cable coming off the Mapleshade receptacle and going to the balanced transformer... and at the end, the cable out of the Uber and going into the Brickwall, both have QSA Power Jitter Power Conditioners – Yellow on the AC ends, the QSA things looking like over-sized ground lifter adapters, but they are power refining units.

Fun to play with power! I'd love to hear about your balanced transformer tests with and without your Puritan setup!

this is not dissimilar to how some high-end Turntable speed selectors are in that they put in a pot to control frequency of the electricity and run it through what is by all purpose just an amplifier.

I just received my Core Power Technologies Equicore 1800 MKii from Mark Shifter (formerly owned) and I am now a firm believer.  Needless to say, he has been very helpful and gave me a great deal on this balanced power conditioner and the floor noise is so noticeable that I am hearing instruments in more detail right off the bat.  Well worth it.  Next are the digital fuse boxes that should be coming soon.

Randy,
Thank you for the reply.  Mark has been great to work with and he provided sound and honest advice.  Very responsive and would not hesitate to call you back in a jiffy.  Glad I got the power conditioner from him.  To date it has been the most dramatic improvement in my system for such a very modest price compared to other balanced power conditioners on the market.  I hope you enjoy your power conditioner as I have and yes they are very heavy!
