I found a link to an article:

http://www.spectrum.ieee.org/WEBONLY/wonews/jun05/0605ngeek.html

about improving audio from a DVD player. First step: swap out bridge
rectifier diodes and buffer cap on the line side. Second step: exchange
the X-rated caps across the line voltage for non-certified audiophile
caps costing $13 each!

What oh what has become of the IEEE?

That is indeed weird. I would never advise anyone to compromise safety
or violate UL regulations.

Often the best approach in audio gear is to get rid of switchers
altogether and replace them with properly designed low noise linear
power supplies. Your electricity bill might go up a few cents per month ;-)

This article was featured on Slashdot -- http://slashdot.org/

The comments on it are pretty good:

There, I knew it was a good idea to drop out of the IEEE about 30
years ago.

I dropped out 40+ years ago when they started charging an outrageous
price for the Proceedings.

Re-joined about 5 years ago so I could get member prices for copies of
papers.

To access that information, you MUST first:

1) Have a current membership of the IEEE,
2) Have a Credit Card
3) Part with USD 25,-- to to download a paper, that either MIGHT have the
answer your question (but, equally likely, instead might be an answer to the
researchers problem: "How do I get Job to pay for my trip to
<nice-conference-location>" ....

I am getting sooo cynical over all those "URGENT - ABSOLUTELY THE VERY LAST
CHANGE" BUMF envelopes.

Which is entirely *ILLEGAL* to do !

Apparently turned into a talking shop for buffoons.

The idead of improving a producvt with 'boutique' parts is plain assinine.
Manufacturers already use the best part for the job at the relelevant price
point.

Rather than buy a $150 CD player and 'upgrade it' with $150 of 'boutique
parts - just go and buy a $300 player. The manufacturers can buy parts far,
far cheaper than the individual can and aren't to dumb as to do some of
idiotic things suggested in the article.

What bothers me almost more than anything is that author apparently thinks
that 'boutique' caps for EMI suppresion on the ac line side will have the
remotest influence an audio quality.

Also the concept of 'better bass' by tweaking the PSU is idiotic when
applied to a CD player. The load on the PSU is essentially constant. It's
not like a power amplifier at all. Essentially the author apparently knows
nothing about good practice for audio power supply decoupling too.

The author probably thinks DVD players have tooobz in them ;-)
