I was reading in another proaudio forum, that some guys use there API 512's for preamps (in a lunchbox). But what they do different is attach a bigger load (resistor) to the pre amp to make it sound smoother. For instance, they said that the API 512's were made to be installed into the slots on an API console. However, the circuit load on a board that size is signifigant, when campared with the circuit load contained in a lunchbox. Now one guy says that he read using a 600 ohm resistor was better than using it alone. His reasons were that, the load induced a more closely matched load from an API console, thus making the tails (peaks, ect.) have a different / better sound. And another guy says that a 1200 ohm resistor is better, because it is closer to an actual API console circuit design. Anybody else do something simular? I have an API3124+, and they are the same preamp as the 512's. Does this sound like it has any real truth to it?
