Isolation Transformer or Power Regenerator

How are they different? Is one better than the other?

Let’s first just I assume that I have bad power. I have a Topaz 1.8 (.9 balanced) that I put my McCormack DNA-1 Deluxe (SMcAudio silver upgrade) on recently and the difference in sound was night and day. Was expecting subtle changes but not dramatic changes. The amp right out of the wall did not sound very good at all, which just did not make sense…it’s a good amp. Putting the iso in line explained why. So, my feeling is I need to get fresh power to my entire system. The Topaz in balanced form may have just enough headroom to squeek by (according to Steve McCormack) with just the amp on it. More would be better.

So, should I get a higher power iso (Topaz, Oneac) for the amp and using the existing one iso on the other gear? If so, does it matter if it is a IE-core or Torroid? Some say EIs let less noise through, some say a good Torriod will equal EI in terms of noise reduction and create less noise (EMI) than an IE. Any final verdicts on this?

Or would it make more sense to get a (Exact Power, PS Audio Power Plant Premier) power regenerator and put the whole system on it. Would any of these have enough headroom to cover my whole system?

I already have a dedicated 20A line to this system. Looking for bang-for-buck solution.

My System:

TADAC Tube Pre/DAC = 25W According to Paul at TAD)
Apple TV = 20W (according to Apple)
DIP (Original) = 10W (according to back panel)
Tivo HD = 40W (according to tivocommunity)
Video Switcher = (don't know but could it be much?)
TV = 240W (according to manual)
McCormack DNA-1 Deluxe = 400 (according to SmCAudio)
Paradigm PS1000 powered (250W/750W peak) Subwoofer = I can’t find this, any ideas? Let’s say 375

TOTAL = 1110W

Main panel to two 5 KVA Xetreme isolation transformers to sub-panel that feeds three major audio systems. Two used isolation transformers for $800. Works very well. Just a way to save some bucks. Not for everyone.

note of caution. if you are dealing with installing an isolation transformer into your home make sure you follow local code requirements.....or your home owners insurance won't cover you in a fire related to power.

the Equi=tech is fully UL rated and is up to code.

some 'esoteric' wall panels are not code and not UL rated. when you install an isolation transformer the limiting part is the quality of the panel and the breakers.

The device Elizabeth refers to maybe the Goertz balanced power outlet. Interesting idea. I have no exprience with it.

does the Equi=Tech meet Canadian code standards as well?

Well, if bang-for- your-buck is where your headed, then you should consider,and contact Consolidated Power Co. in Troy, Mi. as they manufacture many of the lines that are advertized as audio grade products, and although Equitech is considered and oriented as an audiophile, studio product, their pricing is also reflective of this, and they seem short on specs to back up their product. Most of these companies have excellent product,but have different ways of achieving their end result. Never the less, a full blown dedicated power supply should always be ones STARTING point, to gain the most from ones system.
