I bought an hoer wege PS and not satisfied with it.. its dull sounding. Instruments are sounding fuzzy, i could pinpoint before.
The original LM317 PS with just only 2 caps per voltage rail is sounding more dynamic.
Had anyone made /finished this LM3042/3045 design ?

I had a similar experience with LM3045 designs. It is crucial to fine-tune them... to try different decoupling capacitors and different values (within the sensible range... to ensure stability).

In the end, I settled on a linear power supply with paralleled pass transistors and no emitter/collector resistors. Apart from excellent current handling, load regulation, very low noise and low impedance, these types of power supplies allow for easy tuning of all capacitors. This approach can yield excellent results - a very natural sound, close to reality, with a great harmonic spectrum... which is quite an achievement with digital sound reproduction.

So what is your final design? Do you have a technical drawing?
