Balanced vs standard power

I will say that, in a way, I envy your overkill of this power system. Most people seem to think that a plug in surge protector will do the job. The way that you have implemented the devices, i.e. not having them close to the HT/audio systems, is absolutely correct. I can't tell you how many times I have owned devices that made more physical noise than the electrical noise that they were trying to eliminate in the first place!
I took my situation as far as I could by having the secondary feed to the house replaced, as well as having three other houses replace theirs too. We all fed off of the same transformer. Then I replaced an old panel with a decent Square D panel. Then I ran a 10 Ga. dedicated line to the audio system. And finally, I use a BPT balanced device that uses 8 different secondary windings to help isolate one section from the other. Did it help, you bet. I am eager to see what positive effects that your method adds.

Well, I finally had Controlled Power co's Ultra K 600 isolation transformer (15 kva with triple shield and k 13 factor correction ) installed in front of the Isoclean Zero Ohm breaker panel. I have pics but unsure how to upload them here. The benefits were discernible immediately and performance continues to improve at 100 hrs currently.

Oversizing did not hurt performance or create excessive noise as mentioned in this thread, and the results i am getting are nothing short of exhilarating. Unfortunately, I can't comment if its better than 10 kva or 5 kva since I don't have these on hand. However, since the size of the exterior of these units are very similar and the weight varies by roughly 150 lbs from lowest to highest and the cost variation is not significant, 15kva @$3700 vs 10kva @$2900 vs 5kva @2700, I would say opting to oversize is a no brainer.
I am convinced that whether you live in the city, or in the country as I do,
whether your sharing the grid with multiple neighbors,or just a few as I am, that an isolation transformer is one of those audio purchases that is so satisfying that the monetary investment becomes a pleasure rather
than a burden. Honestly, I think some would pay a lot more than $3650 to get this kind of performance upgrade. But Controlled power has no idea of this, yet. And I'm sure some savvy audio dealer may eventually get them
to tweak their design with audio applications in mind.

So while the balanced vs standard power debate rages on, I am thrilled with my current set up.

Natan6355,
Hello and congratulations on your sucessful implementation of the balanced power (BP) transformer. Is the size overkill? I `d say yes (for home audio components) but absoluttely harmless(and hey, it`s what you wanted).Your results don`t surprise me but are what one would expect.

As I wrote earlier in this thread my experience with a BP transformer (in use 3 years) has been a completely positive move 'without any downside'. The improvement was immediate and substantial, and when I tried putting the components back into the wall outlets(dedicated 20 amp service) the decline in sound is undeniable. I don`t understand what is 'debatable' about balanced AC power at this point.

Thanks for the follow-up. Would like to see that more often.

I, also, recently joined the BP ranks. I’m using a Signal DU-10 transformer wired for balanced power with electronics that can potentially draw a max. of 3400kVA. My findings with BP are similar to that of Zmanastroomy & Charles1dad. By adding a 220uf capacitor to the secondary side of the transformer, this made a HUGE improvement to the sound. The improvement with the added capacitance is far more impressive than BP alone, which was already a significant upgrade. The down side with the added capacitance the trannie generates more heat and noise.
