Equi~Tech vs Torus

chrisr said:

For those of you with Torus units, do you hear ANY hum from the unit? Particularly for the stand-alone units that can be placed on an equipment rack?

Thanks.

My RM 15 Pluses are very quiet. You almost have to put your ear on the unit itself to hear any hum. I have heard that the equi-tech component box units have audible hum within 6' ear shot of the unit.

I am still wavering between the Torus wall mount and Equi=tech wall mount units. They accomplish noise reduction in different ways. Equi=tech has balanced power out and Torus does not. There is no way to A/B them so at some point I will have to just decide.

Both companies have been very helpful in describing their products and deciding which sized unit I need.

The Equi=tech unit is a couple thousand more expensive than the Torus so that isn't a huge consideration.

I know 2 people who switched from Equi-tech to Torus after A-B comparison.
The strong points of equitech is bass and strongpoints of Torus is more 3dimensional, open sound, more airy , better midrange and less noisy overall than equitech.

IMHO you should have your mains diagnosed and also ask the advice of Doshi. Does Doshi Audio use mains filters in their units? Can you measure your equipment individual leakage current?

Interesting that you should say that. Nick actually reached out to me after seeing that I was looking for power conditioning assistance. How's that for customer service!

Nick really likes his equi=tech unit which is why I am rethinking this after having made the decision to get a Torus. He said he would look at the specs/technology on the Torus for me.

I am not sure how to measure the current leakage. That is not something I have ever done.

My electrician is coming next week. i am going to ask him to diagnose the mains, if he can.

Thanks.

Very interesting. Were they both using the wall mount units? It may not matter, but I am just curious.

Both went for RM-16 European version which is equivalent of RM-30 or something in U.S.

Torus Power is actually Plitron who in the past made the torroids for equitech and now makes all the transformers for all major USA highend amplifiers manufacturers.

But with both units one can't go wrong.
Both are best of the kind.

Hi Torus WM owners.


I just picked up a used Torus Wall mount unit and am planning on self installing and then having my county inspector sign off on the install.
The unit appears to be straight forward to install, however I want to things to go smoothly with my inspector.

If you have an installed Torus Wall Mount, would you mind uploading a Pic of the 240V wiring and grounding as it connects to the unit?

Thanks

Respectfully, I kinda think you are doing it backwards. I strongly recommend getting a licensed electrician and your local inspector onboard with the instal first not last. Electrical codes are local. Your existing electrical system and how you instal the Torus are related. It all fits together and how someone else did there's in a different system and jurisdiction may not be relevant.

i have to chime in and agree with this advice. Additionally, having a licensed electrician will also give you an opportunity to check/upgrade the ground in your location which will enhance the performance of all your gear

This is how I plan on doing it. My electrician is coming today so he can review the specs of the torus and equi=tech and provide me with a plan.

What is the preferred approach to the ground? Nick, I know you like to use a ground strap. What else should be considered?

The electrical setup (and room construction/acoustical setup) are the foundation of the listening experience. We all love to talk gear and this stuff is not sexy. The fact remains that all of us have electrical distribution in our houses that complies with code for safety but was built to a budget. A little attention to where the neutral bonds to ground, the number of rods used for the ground and their impedance will dictate how your system responds to noise. I would recommend having an electrician check the condition of the grounding rod (in free standing houses), if possible have them sink in a couple additional. Tie them together with good copper and build a buss bar ground at your breaker/disconnect. You can use copper ground strap to tie the ground rods to the buss if possible. Ground strap has much more surface area and therefore less impedance at higher frequencies which will provide more lightning protection and a better RF shunt. My personal preference is for balanced power. It allows for common mode cancellation in the primary of the individual equipment, separating the neutral from ground, lower shock hazard and balanced current draw. I build my gear with schurter iec inlets that have dual fuse protection and ground chokes to take advantage of balanced power where available.Additionally, in my experience, power filtering in the digital side of my audio rig has provided benefits.
