Also be advised of a few things.
1 - The digi001 converters are not really all that much better than many other converters.
2 - The digi001 has a "wave driver" so that other pc applications can use it, BUT, it only allows those programs to use 2 channels! Also, the wave driver is "buggy" right now.
3 - PT software WILL NOT work with anything other than PT hardware. You are stuck using the digi001 with PT on a PC. (that may be your aim)
4 - PT software uses RTAS plugin's and does not support VST and/or Direct X plugin's. Plugin's for PT systems tend to cost a lot of money.
5 - PT LE software offers really NOTHING I haven't seen in Sonar, Nuendo, Vegas, etc....It doesn't sound any better either. It DOES keep the master buss from clipping though, and to me, that is very problematic because the audio volume is reduced. I have verified this comparing 8 tracks of audio, with no faders turned down, and nothing on the master buss being turned down, no dithering, etc....Those same 8 tracks made into a stereo .wav file in Sonar and Nuendo had digital peak distortions, the PT LE outputted file DID NOT, and the PT LE file was MUCH quieter. I do not like that because obviously, PT LE takes it upon itself to "fix" the overload problem by reducing the overall audio volume on the master buss. WRONG!!!
6 - PC's running os's on the NT platform and Mac's are about as stable as each other. As stated earlier, PC's will support more software/hardware, and the software/hardware tends to cost a bit less without usually sacrificing quality/features.
7 - Mac users will try to pick this post apart.
8 - PC users will try to pick this post apart.
9 - PC and Mac users can both fuck off! These are my OPINIONS, and some of them are based upon a lot of research, computer experience, audio experience, and just plain common sense.
10 - Pick your setup based upon which software/hardware you would like to fun. Nuendo with most any 8 I/O card is going to compete quite favorably with PT LE and the digi001. Consider the above that I posted concerning prices, capatibility, and driver issues when making this post. You will see that PC/Nuendo/average 8 I/O card is almost always going to win.
Good luck.
