How to improve power supply?

Thanks Ja. As you see above I am using the oversize 2Q Equitech unit to provide balanced power. I appreciate your PLITRON suggestion however EQUITECH products are being used by NASA and Ames Research Centre so the quality must be there. Also, I note BETA Transformer Technology Corporation is providing the same to NASA and Military.

Hi K.
I know it's deficient because of the "inordinate" gains I obtain from using a 'combination' of ac power isolation & conditioning devices bought to enhance my listening. I am using -and need to use- an Equitech 2Q balanced transformer, MIT AC2 & AC1 reference power cords, and MIT Z Stabilizers--all to excellent effect. Spectral advertised the DMC 20 separate power supply as very effective - and it is the size of the preamp control unit; however I don't find that it is good in the real world (knowing nothing of lab tests/performance). Perhaps it's excellence is in it's ability to allow me to hear the gains by my power products? But, I expected it to provide quite clear power on it's own. Do I expect too much?

Thanks Bomb. I don't want to start a disagreement but in my understanding regulation does not provide "clean" power. It provides a degree of stability, ie regulation within given parameters. I may not be up on the latest facts so I will do some research before commenting further. When I complain the PS is inadequate it is based on the statements by the products representatives when I bought the units new-- that the PS made the pre virtually immune to ac powerline disturbances(noise). Oh well, I will look into the info that has come into this thread and probably have more questions. I'm not in the least interested in technical aspects but a degree of self education seems helpful in this hi-fi / well , music listening hobby. Thanks for your input.

Hi Rod. My biggest efforts have been to remove noise. Equitech balanced power, MIT, Furutech. All to "great" effect. Love that silence.

Geoff, I don't understand.

Geoff, I understand and agree with the goal of eliminating stray magnetic fields; but I don't understand 'how' to do it.

How should I "Mu metal the transformer"?

Good morning Geoff and a big thank you. Listening to classical gets better for me with every refinement. I will look into Mu metals to find the most appropriate and post it here. Using the cork makes perfect sense. Maybe there's a sandwich with cork that can be more effective. Looking into it. Enjoy the day :-)

Thanks Rod, that makes sense. So basically I take it there should be 'isolation' material as a "washer" between the afixing bolt head and transformer surface as well as under the transformer.
I am going to check the torque required to loosen the bolt, which will be more than it needs to be retightened. Thanks for the SORBOTHANE idea. Coincidently I've read a bit about it lately and it sound good to me. If it's good enough for NASA and the Liberty Bell--it's good enough for me!

Thanks Rod.

Rod, finally had time to check Wiki article. Very informative and food for thought. Thanks again.

I've just come back to this post. Rodman, I'm finally getting around to my gear as I may need to send my pre back to Spectral for some type of switch for changing phase. I'll research your info again and post more soon.

Just read about GIRON from LessEMF.com. Any experiences?/ Comments?
