The biggest advantage to getting the separate phonostage is that it will have its own power supply. That could, probably would considering VAC's reputation, give you more of everything from vinyl playback. I'm sure Kevin could tell you what the differences will be. Of course it is still up to you to decide if it is worth the extra money. But if that isn't a big issue, I'd say go for the separate unit. Also, a small benefit is that if you do listen to digital for any length of time you can leave the phonostage off and save the tubes.
