:-) bravissimo...finalmente...
ricordatevi che Creative labZZZ è solo Vetrina, Pubblicità e Fumo
negli occhi al popolino...di asio 2, di latenza, dei pre-amp di qualità,
ecc...ecc...ecc...non gli frega assolutamente niente...

Dove si trovano recensioni della audigy 2 e eventuali problemi di compatibilita'
come la prima?
Ciao,
Lorenzo

 problemi.
occhio, la 2 è stata recensita da tomshardware che sostiene sia ottima... ho
visto alcune cose nella recensione che non mi sono piaciute troppo, comunque
credo che la Terratec sia ancora preferibile in caso di utilizzo per home
recording di basso livello.

Ecco alcune parti interessanti della lunga recensione:
"...Apart from the Audigy 2 DSP, Creative Labs has used some new chips
to ensure the card really does support 24-bit/ 96 kHz playback,
recording and DVD Audio. The key element in this support is the Cirrus
Logic CS4382. This is an eight-channel DAC (Digital to Analog
Converter), providing 6.1 and 24-bit/ 192 kHz support for playing DVD
Audio. Here are the features of this classy chip; Eight channels; 24-bit
conversion; 
4 to 192 kHz sampling rate; Dynamic Range of 114 dB; Total Harmonic
Distortion -100 dB; PCM and DSD format support; Volume control in steps
of 1 dB (transition without clicks); Simultaneous support of two
synchronous sampling rates. 
When Creative decides to go for 24-bit sound, they don't do it by
halves. The CS4382 enables the Audigy 2 to support 24-bit/ 192 kHz
playback and even reproduce sound on eight channels (5.1 for DVD Audio).
And CS4382 is also compatible with the Direct Stream Digital (DSD)
technology used for SACD encoding. 
...Another component not found on the Audigy 1 is the Sigmatel STAC9721.
This is an AC97 codec designed on the whole for internal inputs since it
is limited to a maximum sampling rate of 48 kHz. So, it acts as an
internal DAC and uses delta sigma technology, the most usual for
digital-to-analog conversion. Its signal-to-noise ratio is given as 95
dB, and the chip has a DAC and an ADC (Analog-to-Digital Converter) with
the following analog inputs and outputs: four stereo inputs, two mono
inputs, two stereo outputs and one mono output. 
...The objective tests with Right Mark Audio Analyser proved this
unquestionable quality. Just look at the results for playback in 24
bits/ 96 kHz with the Audigy 2 Rear Out - DMX 6Fire 24/ 96 Line in Rear
test line...Here is an overall table that speaks for itself, giving
excellent marks at practically all levels.
...The 16-bit/ 44.1 kHz tests gave positive results, though not the same
level of quality. This is because when the Audigy 2 resamples all the
44.1 kHz flow rates in 48 kHz, corresponding to the DSP's internal
frequency, rates above 48 kHz do not get resampled. So here we have a
paradox: the Audigy 2 produces near-perfect sound in 24-bit/ 96 kHz
playback (i.e. DVD Audio), but is not as good in 16-bit/ 44.1 kHz
playback (such as CD Audio). You can see the test results are generally
positive, except for the intermodulation one. This is evidently due to
resampling in 48 kHz....
...For someone who only plays games, the Audigy 2 is the very best sound
card. But they will only be using a small portion of its capacities: the
EAX Advanced HD, CPU performance and surround sound quality. All the
other functions, however attractive, make it work out to be very
expensive. So, our gamers would be better off with the Audigy 1, which
has all the advantages of the Audigy 2 in games, with a slightly lower
sound quality. On the other hand, if you use your PC for playing music
or watching DVDs (as gamers may do), then you have no reason to
hesitate, provided you use speakers worthy of the Audigy 2. And you will
be satisfied with the Audigy 2 Platinum and its IR remote control and
digital inputs/ outputs. Amateur musicians will also love its
converters, the full 24-bit/ 96 kHz support and the ASIO drivers. "
