Can someone please explain to me the advantages of having a pre amp and power amp combination? Waht is the pre amps job and what is the power amps job and why is having amps dedicated to each job better?
I have a Rotel RA02 and know it can be used as a pre amp to go with a power amp. If I was to use a power amp a couple of price points ahead of it would I hear much difference or would it have the RA02 character?
Feel free to be as techincal as you want in your explanation, I have a reasonable understanding of audio electronics!
