I have a 19VDC3A Laptop Power Supply powering a JFET BOZ preamp and it sounds very nice. For the hell of it, I hooked up two 9V batteries in series and it sounded quite a bit better. Clearer and deeper is all I can say. I do not think it sounds better due to the difference of 1V.
Now the question is this. Can I make a dull sounding powersupply like this Laptop SMPS better by just adding filters? Could it be all about better filtering or is there something more to it?
I could easily build a supply with a tranny, rectifiers and CRC filter, but I have a quite a few of these laptop power supplies (eight to ten of them) and wouldn't mind using them.
I have parts to make a CRCRC arrangement with C=2200uF and R=.5 ohm on this laptop supply, and before doing it decided to ask here first.
I also have connected two of these same laptop PS to get dual rails and a center tap. Works great as a 19v - 0 - 19v at 3A supply. I have been thinking of using it to power a Zen V5, until I tried the battery thingy mentioned above. I also have enough parts to further filter the dual rails for this supply with a CRCRC arrangement also.
Am I kidding myself on thinking these supplies are usable in Audio?
