Hi All,

After reading your posts, curiosity moved me to try, so i spent the
long Week end (from friday to tuesday, was Holyday in Italy) lissening
to different music and looking for differences.

I was skeptic, becouse i knew and i'ìve personaly verified that you can
convert from wave to flac and viceversa any time you want, but if you
compare the two wave files are BIT PERFECT, so i was realy surprised
about the results:

in my personal experience, limitetd at SB+ and 7.4.1, there is a little
but audible difference in playng Wave or Flac files, more strange (to
me) is that the same type of differences (reduced) still remain if you
play a flac file 'converted' in wave at the server side.

In few words those are the major difference to me:

a) Stereo Image: 

Playng the Wave file, the scene is more focused and deeper, but
smaller, means that if you play i.e. "Old Love" from Eric Clapton
Umplugged album, mr. Clapton seems to be 10 cm shorter, the bass is
behind and not on top of the voice, the piano asolo is not so far in the
left. 

b)Sound 'color':

Playng Flac, voices, arcs and cimbals are a little bit 'harder' and
cold, some 'electric' take place, in wave they are smoorher, some more
air around and more 'natural'. No big differences in bass, maybe a bit
more control in wave.

All above IMHO and i want to point that differences are small but
auidible in my system, if you pay attention to details in a critical
lissening session. Also in 'blind test' I always recogniced the WAVE
(non always the flac and the flac converted in wave)if played in
sequence.

Last point: often in the past, after a long listening session (I love
Wagner, so you can imagine how long they are...) I founded myself
claiming about some roughness and "nasality" (hope is correct in
english)in the sound, that make me tired, my first impression today, but
i've to try for much more time, is that playing wave files make this
point better (far away form LP's, anyhow).

At the end of the day, and just to give you an idea, changes are
similar to the one I had using an AC insulator transformer on the
Amplifier power line.

I personaly think is not a matter of file format that is proven to be
truly lossless, but some difference is in, maybe some tech guy could
think about? 

My library is FLAC and now i'm thinking to move it back to WAVE, payng
the cost of more disk space.

Hope to be usefull, some other guy had similar experience?

regards, Marco.
