Is an isolation transformer better than a power conditioner?


I was never thrilled with my Shunyata Triton/Typhon pc.

It improves the SQ but not dramatically. And it is two large chassis that take up a lot of real estate. And not particularly attractive. And we’re $18K new! One would expect transformative performance.

Just went to great lengths and expense to run a dedicated AC line. $4.5K of special Oyaide cable, duplexes and cover plates. And $1.2K electrician.

It was also highly recommended that I also go with an isolation transformer. Went from Torus to Bryston to Equitech. Focusing on the balanced power Equitech.

Getting one, I am curious to know if it will “blow away” my T/T as I have been told.

And with the dedicated AC, maybe not plugging my amps into the new duplexes but the Et would be better. Or plugging in the Et to the T/T and the T/T into the wall.

But I sure would like to get rid of the Shunyatas.

The change in SQ with the Shunyata Triton/Typhon PC is truly tremendous.

Every LP is  greatly improved but the changes are most notable on classical.

The instruments are separated with air around each. There is layering with 3D presentation. The emotion is more present than ever producing a gripping sound.

Taking the Shunyatas out the soundstage collapses and all of these factors go away. I am still wanting to get  PS Audio P12 but may wind up using it together with the T/T.

 

I have Torus TOT Max in my system. I'm afraid to try plugging my integrated Luxman into the wall directly because it may sound better, thus there will be no surge protection.

A very valid concern. I think the equation changes over one’s lifetime as you realize you only live once and for a finite time. What is the real probability of having your equipment fried? I lived in Tucson Arizona for 25 years… I was in charge of a data center that went down because of thunderstorms every summer… yet have never lost a single piece of audio equipment.

Equitech "balanced" power is used by countless professionals who must have clean power. Travelling bands love balanced power by Equitech. Recording studios. University research labs, etc. Check out Equitech website, perhaps they have a customer list. Anyway, their product is based on "basic" electrial principals. Those don't change :) Good luck with your research. Pete

Well, you can pay for a $189.00 or so for a Tripplight isolation transformer.It has 1800w capability and regulates down to 85v to 145v to 120v.  It also has RFI suppression. Filters spikes and noise.  I use a Furman power strip in front of that which also has RFI filtering and a 145V clamp circuit which shuts down power at that Threshold to protect the isolation transformer. Probably under $300 total.  My primaluna is silent with this turned up loud. No hum no hiss. Or you can pay thousands if that makes you feel better. I dare to  compare.  $$$$$$$ does not always add up to better sound.

FWIW. Balanced AC is simply 120 Volts that has been split evenly across two AC mains. One phase is +60V while the other is -60V. The mains are always 180 degrees out of phase across the load and therefore sum to 120 Volts, the same voltage and frequency for which equipment power supplies were designed... When the incoming 120 volts is split into 2 60 volt lines 1/2 the powerline noise/distortion is on each 60 volt leg. When the legs rejoin, out of phase -to make 120 volts- the 'mirror image' noise/distortions of each leg cancel each other leaving dramatically cleaner power. This is not rocket science or magic; and it works. Complementary products can certainly improve on this if wisely chosen. Experiment and have fun. 

I'd go with one of the ultra low capacitance Ultra/Extreme/High Isolation transformers from the likes of Topaz/MGE/ECA/Xentek/Elgar/Daitron. A lot of them come with balanced output (and it not they can be wired that way). They may also come with a film capacitor on the outlet output. The best of the lot will have .0005, .0001, or even .00001 pico farad capacitance and -150 dB+ and -65+ common and normal mode noise reduction respectively. Then have a nice passive power strip plugged into it to plug in all your components.

The BPT 10.5 and 3.5 units also seem to be a real bang for your buck with a giant Plitron toroid, and extra shielding, premium wiring and outlets, capacitors on the outlets, and other goodies.

As for a UPS, they are a great option, go for an on-line (not like internet online) double conversion unit from the likes of Eaton, Liebert, APS, Cyberpower, MGE, or SurgeX. In my research Liebert has the lowest THD and highest Power Factor capabilities. I cannot speak for other noise reduction capabilities. I know Furman, Monster (in the past), and PS Audio make or have made UPS' but I am not sure if any of those are on-line units.

There's a better option of ac power source/power supply generators that are better then UPS' or audiophile regenerator units. They are sine wave ac generators where you can choose the frequency and voltage output, but they rarely have a built in outlet, and cost a lot for high VA/Watts output. You can find quite a few with 900 VA output with a single duplex, not many with output over 1,000 VA. I just saw a couple of Titan MAC 01 units on eBay with 1,000 VA output.

There's also Topaz and MGE line conditioner/power conditioner + voltage regulators. They have a large transformer in them that is saturated by a large capacitor but aren't just isolation transformers.
