Noise will come down to it's gain multiplier. You'd have to consult the manual. If it has a low gain multiplier, but more current output, then it probably has the same noise as the mini-X, but will simply gain volume faster. If it has a higher gain multiplier, it will be noisier.
UPA200 is 29dB gain.
Mini-X doesn't have it's value in it's manual.
