The short answer is: Yes, if you are playing a 20 or 24 bit audio file. 
The A/D & D/A converters are 20-bit, which allows cleaner transfers and
fidelity.

Now the 'long' answer:

This is a complicated issue. The Multisound Pinnacle and Fiji soundcards are
constructed on the Motorola 56002 DSP, which is capable of 56 bit internal 
processing with 24 bit I/O. This means that the Pinnacle and Fiji are '24 bit
internal' soundcards. 

The Pinnacle and Fiji are fitted with 20 bit Analog-to-Digital and 
Digital-to-Analog converters. 

This means that you can record a sound to the Pinnacle/Fiji card in a maximum 
bit-depth of 20 bits, even if you save the sound as a 24 bit PCM Wave file 
(which the Pinnacle/Fiji can do). The remaining 4 bits will be left in the 
Zero State (i.e. essentially unused). 

If you have a 24 bit Wave file on your hard drive and you play it through the
Pinnacle/Fiji, you will hear the file in 20 bit resolution through the card's
20 bit Digital-to-Analog converters. The 24 bit file remains a 24 bit file; 
you will just hear 20 of those 24 bits. 

So the final word on the *hardware* is that the Pinnacle/Fiji can record at 
20 bit resolution, can edit and save PCM audio files in 24 bits, and can play
them back at 20 bit resolution. This is actually a higher resolution than the 
latest Alesis ADAT digital tape recorders! That's not too shabby for an ISA 
card designed over half a decade ago!


NOTE:
Most Windows audio *software* can record at a maximum resolution of 16 bits.
Check with the manufacturer of your audio software for more information.
