Here is a Torus Power Single A 20 power conditioner. Please see the photos for the excellent cosmetic condition. There are 2 small nicks in the font edge at the top of the face plate. They are less than 1 mm.From the Torus Website: Isolation is combined with proven proprietary technologies from PLITRON in the oversized toroidal transformer. NBT works as a low pass filter using the controlled leakage inductance and capacitance within the transformer to cancel common mode and differential mode noise. LoNo technology has been used for years by high-end audio companies who demand silent transformers. Imin technology reduces inrush currents. UST provides additional common mode filtering using a highly efficient faraday screen.” “Low impedance output with balanced high power primary input provides the most unconstrained, yet protected, energy source available to your equipment.” Well, now that we�ve been buried in acronyms, we�ll just have to go a little deeper to find out what they all mean, and do! According to the Torus section of the Bryston web site, NBT stands for Narrow Bandwidth Technology, which “substantially attenuates differential and common-mode noise without external circuits such as low-pass filters. NBT also starts to attenuate noise at lower frequencies, starting at 1 kHz.”
This is a one owner unit and is 100% original and 100% operational. I will answer any pertinent questions. This is a used power conditioner and it carries NO warranty of any kind. It will not arrive DOA because it works. Local pick up is OK. If you are local I will even bring it to you. The power conditioner will weigh in at 105 lbs boxed. Original packing is not included but it will be double boxed for safe shipping. I am an excellent packer. Please see my feedback that includes many unsolicited positive comments regarding my packaging. I have an account with FedEx to save on shipping. Please contact me for a shipping cost. Do not use the UPS or Fedex shipping guides provided here. Paypal users will pay the 2.9% fees they charge me.
