Depending upon how long all of the speaker & interconnect cables have been in place, I’ve found that removing them & cleaning both the cable terminations & the jacks on the speaker or electronics & replacing them can make a positive difference.I just use rubbing alcohol & cotton swabs on wooden sticks designed for this. Let any residual alcohol evaporate ( which it will pretty quickly) before re- connecting. I know there are specialty products for this but this seems to work just fine.
Are There Improvements that Can Be Easily and Quickly Made Without Buying More Stuff?
I appreciate that there are many people on this forum who have put a great deal of thought and effort into how to improve their audio systems. Most of the discussion relates to upgrading equipment. This is natural as most people here want to improve their music experience, and better equipment is a way to do that. I’ve taken advantage of this and made 5 or 6 upgrades over the last year! The result has been great! But are there some simple steps that can be taken that can be overlooked by someone who is newer to audio?
As examples I’ve read that facing a sub towards something like the back of a couch will improve its sound. And for rooms with bad effects that can’t be fixed, move the listening position closer to the speakers.
