Preamp and Amp how much influence each contributes?

I've heard preamps that influenced the sound character as much as amplifiers have.

But the reality is amplifiers are a more difficult product to consider because of the need to consider what sort of load it is driving (i.e. the speakers). And thus the larger number of questions and opinions about amplifiers.

I don't think an integrated amplifier is automatically equal to lower sound quality when compared to separates.

@kfz03110 if you're not sure about your speakers yet or if you go through speakers more frequently than your other components, it would probably be wiser to allocate higher priority to your amplifier budget in order to get an amplifier that will be capable of driving harder speaker loads.

In other words, if you change your speakers you might find your existing amplifier isn't driving them to their full potential. But that wouldn't be the case for the preamplifier which would either still be paired with the same amplifier or paired with a different amplifier which is still likely to have a high enough input impedance.

(That's all ignoring the question of sound character.)
