Apparently the numbers of consumers that are providing their 'HT room' with
more than two speakers are increasing considerably. I know it is a matter of
personal test and subjectiveness; however I would be interested in knowing
what you think about listening conventional stereo CD or any two channel
music through four or five speakers. What's your opinion about it?

I think it can sound very, very good, if done correctly in a
well-setup system. Done well means using Lexicon's Logic 7,
Meridian's Trifield, or Dolby's Pro Logic II. There really isn't any
law that a number of channels must be reproduced by the same number of
speakers, and psychoacoustically speaking, two speakers in front
cannot reproduce all perceptual cues in an optimal or even useful way.
Some advantages:

1. Reduction of comb-filtering artifacts in centered images due to
phantom imaging by using a center channel.

2. Moving hall ambience to the sides of the listening position so the
ambience can properly envelop you.

The effect you hear shouldn't be the obvious presence of speakers to
the sides or rear, but instead of a deeper, wider, more solid front
soundstage. The subjective impression is being drawn into the
recorded acoustic space, instead of observing it through a window.

Hi,

Regarding Pro Logic II Music: Is there any compression or loss of
resolution when an audio CD is played in that format?

Thank you for taking the time.
Regards,

There's no compression, but there is steering which some could argue
is a loss of resolution since the signals in the left and right
channels are being altered, but it's not a clear issue since the
typical audiophile definiteion of resolution is so ephemeral. There
are of course good and bad implementations of algorithms, some of
which may sound worse than others. I think Dolby's gotten around this
by supplying reference code that's supplied with DSPs with PLII.

The best thing to do is to have a listen for yourself on a good system
(like a Meridian or Lexicon system), and decide with your ears whether
it does anything for you. Make sure such a system is well-setup with
regards to speaker distances and levels.

Since you said the magic word, I suggest that the Meridian TriField
system does wonders with stereo sources and a 5.1 system (or as many
channels as you have).

That's my experience with the Lexicon processors. Dolby Pro-Logic II works well
in many situations too.
