Cheers!
I'm just starting to try to understand the working of electronics in
amps etc. and reading all this bits and bobs all helps to start filling
in, the big big picture :-)

Hi Brian,
Yes, that is true - I just didn't realize that the equivalent series
inductance (ESL) would be so high for the electrolytic that it had an
effect below 20kHz. I found this document showing the effect of ESL in
a very nice graphical way
Here's another article on replacing/bypassing Capacitors..

Bypassing capacitors makes for better high frequency transmission.
Here is an explanation:

The output capacitors in the original Squeezebox are fairly
Yes, I'm also confused. Connecting capacitors in parallel certainly does
not amount to bypassing the original capacitor!
If you have two capacitors with capacitances C1 and C2, the resulting
capacitance after connecting them in parallel will be Ctotal = C1 + C2.
So, I'm also wondering how will

What you say of capacitors in parallel is only true of perfect
(theoretical) capacitors, but those we buy are not so. They have
capacitance, resistance and inductance,
All you do is put them across the capacitors already there.
Are you saying that you connected the new caps in parallel with the old
ones?
If so, how come that the resulting 110.1 is making a noticeable
difference in audio quality? Am I missing something here?

dpuopolo - would you mind, posting a pic? so the ones of us that are
interested and not knowing much about electronics and have a soldering
iron, may be able to follow a picture while not understanding the
electronic words.
Many thanks :)

If the OP means the electrolytic capacitors on the analog outputs, than
it has nothing to do with decoupling capacitors. A decoupling capacitor
always has one end connected to the return-path of the signal... which
I recently bought an original Squeezebox on ebay. When I opened it up, I
noticed that the output capacitors were large value (110 uf)
electrolytics, and were unbypassed. I bypassed these capacitors with .1
uf metal films bought at Radio Shack (If you have not used these caps,
