[sdiy] Better testing techiques for audio circuits

[Justin Owen]

One follow up question to this...

How useful are simulations like SPICE in showing noise and distortion level in a circuit?

...or more specifically - if I was to simulate a 'bare bones' version of a simple, discrete circuit and a 'precision' version of the same circuit - how useful would simulations be in showing any differences between the two with regards to improvements (or drops) in noise and distortion?

Thanks again.
