Check Settings > Advanced > File Types. There are rules to convert to
both AIFF and PCM (WAV with no header). Since AIFF takes precedence in
the server code, it would be streamed. If you want to force PCM you can
simply disable the AIFF rule.
You can also check out the convert.conf file, which has the commands to
external programs that are run to do the conversions. For FLAC the
decoding rules are shown below. You can override any rule in the file,
or add new ones by creating a file named custom-convert.conf (placed in
the same folder as convert.conf).
Code:
--------------------
flc pcm * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs --force-raw-format --endian=little --sign=signed $START$
$END$ -- $FILE$
flc aif * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs --force-raw-format --endian=big --sign=signed $START$ $END$
-- $FILE$
--------------------
The only difference between the two is the 'endianness'
(http://www.google.com/url?sa=t&rct=j&q=endianness&source=web&cd=1&ved=0CCcQFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FEndianness&ei=Wv8KT46VJoe62wWah-W3Aw&usg=AFQjCNEcYWBropgp-Eoe84G6njx-XOfysg&sig2=NZTWK-2ELkeODaW7r3n3Bg)
of the data. In both cases the headers are not included in the stream
(the --force-raw-format option), so only audio data is sent to the
players.
Which is 'better' for the Touch? That may depend on the endianness of
the ARM processor used in the device. Turns out that ARM processors are
"bi-endian" - they can be set to treat data as either big-endian or
little-endian.

I have no idea which is used in the design of the Touch.
