Default I've upped my on-chip capacitance. Up Yours!

Haaaaha! My coworker ... 15 years ago told me a joke with that in it and I've been waiting ....

I've upped my on-chip capacitance! Panasonic THA 15,000uF, 63V

Chipamp, upped capacitance!.jpg

Up Yours!



P.S. All Hail the Great AMT Heil!

I've tried similar and frankly there is clear audible result/ advantage in increased capacitance. Sounds are surprisingly good
Try it and listen ...then disparage :-)

Strange... according to "theory" increasing the caps (2x1000u -> 2x10000u) in my pre-amp also would be to no avail... sound and soundstage however did improve.

I guess the lowered impedance of the psu is audible, even at low current demand..

Chipamps can sound great, I have made few inverting with Jfet buffer on the front, and the results is excelent sound.
I am working on transconductance version.
Any idea if regulated power supply improves the sound of chipamp? Anybody did direct comparison?

There have been several threads were genuine improvement was noted when the supply was regulated. Can't re identify them off hand tho
Search a bit?

And there are who say that regulating kills the sound.
I have one regulated and one unregulated, but different chips. Both sound great. So nobody can tell I chose sides
Still, big caps are a must.

IMHO: Looks like one of the caps on top is a puff. Should be replaced to be safe.

puf used to mean a low pico-Farad capacitor.
What do you mean?
