Is the ONLY difference in the signal path when using the phono input vs aux or tape input, the fact that it goes thru a little phono stage/circuit board?

Yes.

The phono stage boosts and equalizes the signal from the turntable.

Yep, that little stage adds around 20-30db of gain and does the RIAA compensation curve correction. If the unit supports MC type cartridges also then there is another 20-30 db gain added on top of that.

This added gain makes it more vulnerable to noise and is why there is usually a grounding lug near the inputs to wire to the turntable.

Yes. And that is a big difference.

 

[soundweasel]

Yes. And that is a big difference.

What would happen if I ran my CD player through it? :scratch2:

 

[jfine]

Thanks guys I know its a big difference. I just want to make sure that after the phono stage, the signal path goes the same place as the aux input. No other funny capacitors or what not.

It would sound terrible.
