What does the SSPS sound like; I am a bit suspicious of the inductors' effect, both L and R.

Hi fmak,

One of the reasons I contacted Norman was to order a pair of SSPS; I'll let you know how they sound!

The chokes are 'CMC's or common mode chokes designed to block out capacitivily coupled noise that makes it through the transformer. They are often used in digital work where their high leakage inductance filters out RF noise... the result will be quieter backgrounds, better detail and definition.

FWIW

Thumbs up Another power supply kit

This one is at http://www.welbornelabs.com/ps1.htm. The Linear Technology LT1085CT/LT1033CT are the best three terminal regulators that I know of.

Default large gifs`?

Hi jwb,

how did you get to post that gif image? I tried to post a scan the file of which was only 20 k in size, but the forum computer refused to accept bitmap images larger than 800x600. How come it accepted yours?

Eric

Mine is actually a reference to my own website. I didn't upload it to the forums.

Theory apart, not necessarilly sonically better. My own experience points to low noise, low source impedance as prerequisites. Inductances and resistances do not help; they seem to suppress dynamics. Pl post your assessment.
