Ripping SACD's can be done but has a couple of major drawbacks:

1) It takes expensive equipment (see below)
2) It takes a lot-of-hard-disk-space!!!
3) It is difficult to play the high resolution music. 

Slimserver/Squeezebox/Transporter etc can't do it, you need other
players. Even so, you may not get the full resolution when playing.

How to do it:

You need a SACD player with a digital out, this is the expensive bit. A
dCS Verdi will sort it, but it will set you back a serious amount of
money.

The digital out will be a firewire. The format of the audio is not PCM,
as pointed out above, but rather DSD and it is copy protected (that is a
native feature of the firewire). So you need to shift it over to a
non-copy protected format. To do this, you can use a digital filter
like the dCS Purcell. That is a digital up/down sampler. The later
versions of this will take firewire input (DSD format) and
resample/reformat it to whatever you like and what you like here is
"Dual AES". The AES format contains no copy protection, so the Purcell
kindly removes the protection and puts out a 192 kS/s PCM formatted
audio signal.

Now, handling this signal is a bit of a nightmare. The "dual AES" means
exactly that; It is two AES cables. You want to feed this into a
computer sound card and record the digital signal to hard disk.
Unfortunately, not many soundcards will handle a dual AES which is a
pretty extreme format. You can find one though, but it will again set
you back a lot of money.

The whole setup of a dCS SACD player, a digital filter and a soundcard
able to receive the 192 kS/s signal is - expensive.

I don't know of any other consumer SACD player capable of producing
digital DSD out, but they might exist. There is also some studio
equipment, notably dCS again, that can do this.

I've compared the quality of SACD to an upsampled 44.1 kS/s source of
the same music (so the CD layer of an SACD recording) and the quality
difference is there, but it is small. I haven't found it worth
bothering really so I use streaming audio via Slimserver and 44.1 kS/s
into an upsampler and very rarely actually play an SACD recording.
