This might make an interesting experiment but it's probably not worth your time. If you have some of those hidden gems that were never released on CD, then go for it. My experience with vinyl recording/restoration software is that it is extremely time consuming, depending of course on what sound quality you're aiming for.
I've never used Pure Vinyl but I can recommend some other options for you Mac:
Bias SoundSoap2 - relatively simple to use and inexpensive at $200.
Waves Restoration - this is the one I use. It's quite a bit more money at $1200 but it's the way to go if you want surgical control over restoring your vinyl.
Keep in mind these are programs for restoration (clip/pop removal, hum removal, etc..) if you're wanting to go that route. Any free audio recording program will do if you're just wanting to record.
