Isolation Transformers
brskie Isolation Transformers Product OverviewThe IS250 is a 120VAC 2.1A 60Hz Isolation transformer-based Power Conditioner offers complete line isolation, continuous noise filtering and enhanced normal and common mode surge suppression. Internal low-impedance isolation transformer component with Faraday Shield offers 100% isolation from the input AC line. Secondary neutral to ground bonding eliminates common mode noise, providing an isolated ground reference for sensitive equipment and an inexpensive alternative to the installation of dedicated circuits and site electrical upgrades. Removes EMI/RFI noise, utility switching transients, background spikes generated by other on-site loads and utility or lightning related surge conditions. Additional surge suppression components placed at both the line input and transformer output combined with full line isolation offers continuous line filtering of a full range of power line noise in all modes. Great, they have very good Gavanic Isolation as they have an air gap, just don’t use them on poweramps better they to go direct into the mains to get the "stiffest" power transfer (lowest impedance) for control. For your source/preamps this is all you need. (Don’t waist your money on expensive fancy "HiFi" filters ect) https://www.newark.com/tripp-lite/is250/isolation-transformer/dp/90B6979 Cheers George |
I have the Furman Elite 20 PFi that I am using with my home theater system. Having so many amplifier channels (11.2) it helps that it has "in excess of 4.5 amps continuous power with 55 amps peak up-charge that is cleaner and faster than a dedicated line from your local power station." Your system contains many excellent components and I believe it would benefit from a component having really fine filtering and surge suppression that the 20 PFi offers. It also protects your internet and ethernet connections. You can read the owners manual here, https://www.furmanpower.com/products/all/component-power/elite-series |

Inakustik 3500P $3.5K!!! I'd go the $149 Newark one above first. Here's the data sheet. http://www.farnell.com/datasheets/2357270.pdf?_ga=2.235938311.78280552.1582701028-203377982.1582701028 It's got no audiophile markup $$$'s attached to it, as it's made for all types of very sensitive non audio electronic equipment. And put the $3.5K towards amp or source upgrades. Cheers George |
No but at $3.5k!!! I would try the $149usd option first. Which ever nothing is still best for poweramps, as they need to have the stiffest connection to the mains, no "resistive components" between their power supplies and the mains zero impedance if possible. Unless you want similar to soggy "tube rectification" type bass. Cheers George |
If the $149 250w isn’t big enough, there are bigger, right up to 1000w, https://www.newark.com/c/transformers/isolation-transformers?brand=tripp-lite But still no power amp should go through any conditioner no matter what the cost. Cheers George |
So how would you know what the Inakustik does or does not?I’m just saying anything between the poweramp’s power supply and the mains "has to" introduce some sort of series resistance. And that "has to" reduce the stiffness of the amps power supply, which has to effect it’s bass performance. VTL’s David Manley (rip) did a very famous paper way back on it back in the 80’s, you should read it changed all views on poweramps power supplies design and how to get their power from the mains and how they should behave, I think for memory maybe even Dan D’Agostino took heed of his words on it. The OP’s Torus do not sell for $200 eitherI don’t think I said they did Cheers George |
Thanks so much everyone. I appreciate the recommendations for the Inakustik 3500P and I am definitely researching that unit. I am still hopeful that some of you have had experience with either the Equitech 2RQ or Torus RM20 rack units that you could advise me on. I am still up in the air about the balanced output of Equitech and how effective it is as opposed to the Torus NBT technology. Two different approaches, but which is better? Thanks again for all your feedback!! Bruce |
