I added an external DC power jack some time ago in this forum to check the possibility of adding battery power supply. The best sounding battery I could come up with was a large Lithium Ion Laptop Extender Pack. Removing the AC power supply noise provides a very open, detailed see through sound stage, problem is a major lack of dynamic's which leaves the music lifeless. My friend Gary had warned me this would be the case as he played down this avenue himself. Our hope is the new super capacitors which are just becoming available will make battery power a reality. But as always at the cutting edge, they are expensive.
Plugging in various DC power supply's I have laying around paints all kinds of sonic landscapes with the Valab.
This you have to hear for yourself, wildly different. (In the end I am holding out for Rhodes to report back on the Paul Hynes power supply.) Hooking up my bench DC power supply and swinging the voltage changes the sound, but no position sounded good to me. I discovered my Bench Supply is for testing purposes only, it sounds like crap, just like the other power supply's I have laying around.
Power supply's are a black art!
I think as Jogi describes, having a "quality" power supply with the ability to adjust the input voltage may make all the difference.
Jogi or Dubai could you take pictures and further elaborate exactly what type of power supply you are using and the mods you performed to them.
