Get the gear you are interested in then listen to it. If you dont like it you change it, I went through 5 pre amps before I found the one that gave me the best of what I was looking for. Its a long process that takes some time. Some stores will allow a couple weeks or up to 30 days to return, you might have to pay a restock fee but thats the price you pay for being a tire kicker. I have purchased used equipment and had to resell when not happy but I learned an important lesson too, for the small amount of money lost it was worth it in my opinion.
