AVR preamp sound quality

That depends on whether the nr1711 is slightly coloring the sound to be more pleasing or not most likly.

How much do pre amps colour the sound? Is the colouring not mostly done by the power amp? Or both?

@davidj1 those will probably sound the same. Get whichever has the most features for the least amount of $$.

It depends in part on the input sensitivity of the amp. What amp are you using?

Looking at either the Model 30 or PM8006.

The PM8006 has a 250mV sensitivity on the line input which is plenty low for either of your listed AVRs to drive. The only real SQ difference I'd imagine being relevant between the 1711 and the 5015 is the different versions of Audyssey, with the 5015 having XT.

EDIT: Looks like the Model 30 has similarly low sensitivity so it could be a good pairing too.

Preamps should be the sole device that color the sound. The amps, if they're proper should be completely transparent - their only job is to make a signal more powerful, and any colouring the amp does is known as distortion, considered bad.

Preamps are where sound is processed - where you can adjust it's frequency response, add/cut bass, add/cut treble, etc. your preference of processor is determined by how you like the way it's colouring the sound. Now, you may prefer uncoloured sound and there are often plenty of things you can do to make the sound more neutral.
