Does anyone have an informed opinion regarding comparisons of SCA mic pres vs John Hardy, or Great River? I realize the "bang for the buck" argument on behalf of SCA. But from a head-to-head comparison of sheer sonic quality, can you hear a difference between e.g. the SCA J99 vs the John Hardy manufactured mic pre? Especially with respect to sonic seperation within the stero field. My dilemma: Do I want to IMMEDIATELY purchase an SCA Unit with say J99, Neve, API. Or would I rather buy the real deals at a rate of 1 per year for the next few years.
