Oh one other thing.
Concerning the difference between a digital or analog mixdown.
I have heard lot's of both that sound killer, and lot's that sound really bad. Just because you may have a 1/4" reel to reel doesn't mean that the machine is very good sounding. Also, good noise reduction tends to help analog decks obtain reasonable dynamic range signal to noise levels. But, anything less then Dolby SR is probably not all that great, and Dolby DOES apply some artifacts to the sound (SR is the best sounding of them all though).
Cheap A/D converters have their problems too.
So, it really comes down to a couple things concerning digital vs. analog.
Is noise an issue with you? If so, you will need a very high end analog recorder with a great noise reduction system to record quiet recordings that just about any decent 16 bit A/D converter will.
Is controlling Transient Peaks in the mix more important than noise to you? If so, analog will be better as it "gradually" distorts transient peaks rather then just outright bad sounding distortion like you would have overloading any A/D converter.
If you have access to a nice analog 1/2 track machine that has some decent noise reduction, you will like the results a lot better then most digital A/D conversions. But price becomes an issue. I bought
my Lynx One card (24bit/48K sampling rate) for $450 bucks, and it has a very nice sound that is only surpassed by A/D converters that cost many times the cost, and also sounds better then all but the best analog 1/2 tracks machines, which cost many time as much too.
So, I am willing to trade a little sound quality for economics in this case. Of course, a nice Studer with Dolby SR will find it's way into my rig when finances permit, but for now, this soundcard works really well.
