My tip:
Start with the best gear you can possibly afford and go from there.
More expensive doesn't always mean better, but inexpensive usually means junk.
Tip#2:
Trust your ears, not what some fool on the internet with a multimeter says.
Happy Holidays and Your Favorite Tips?
Yes, I'm being inclusive.
What's your favorite tip to audiophiles? Here is mine:
If you are using a subwoofer with ported main speakers, consider plugging the ports and raising the sub crossover. Even if you don't have a subwoofer, sometimes plugging one or the other can really reduce bloat. It's worth listening to it since it's cheap and non destructive (assuming you don't lose your sock in the port).
