So why do most of us have preamps? Are volume nobs better?
Can a simple DIY volume knob replace a pre-amp?
If I have only a cd (single source, can I make a simple volume knob instead getting a pre? Since it is simpler and "pure", will the sound better? I know Pre-amp will do some gain on the signal, what is the benefit to have that gain? I am shopping for a pre-amp and come across some people said that a simple volume can replace the pre. Thanks.
