In addition to how changing the gain of a preamp can change sound due to nonlinearity of the gain control, another thing to consider is where you achieve the gain. For instance, I can change the gain on my phono preamp as well as on my main preamp. I have tried it both ways and using the main preamp for increased gain sounds better than increasing the gain in my phono stage.
Will changing gain affect frequency response?
NOT talking about increasing the volume at the listening position by turning the volume up...
Rather, with volume kept more or less constant at the listening position, is there some technical reason for things sounding a bit brighter when the pre-amp's gain setting is increased from -10 db to 0 db (again, volume adjusted downward, accordingly) OR is it my imagination?
Think I've encountered this with my pre-amp and most recently by altering the gain setting on my phono pre-amp. Increasing the gain by moving the jumper to the highest position seems like it opened up the sound from the Grado cart I run.
Hence the question...will changing gain affect frequency response?
Thanks in advance.
