i need someone to help explain how to make a less expensive system sound better, truthfully. with no lies at all.
1 Find the best sounding room to put your system in. Not too lively and certainly not too dull.
2 Set up your speakers (with the treble units near ear height) wherever they give their best sound. It will take some time, patience and experiment. Keep a record of the different positions you have tried for future reference.
Your lovely wife might be able to help you out there but some of us have to labour alone. My wife always finds something more interesting for her to do. It must be over 15 years since she stepped foot in Hi-Fi store.
3 Find some method of decoupling your speakers. There are numerous professional products out there that will help or you could experiment with springs / sorbothane.
4 Remember that @mahgister took his system setup to extremes, and it seemed to work for him, but would you really want to go that far?
5 Plan for the most effective future upgrades but keep in mind that your system is probably already in the top 1% of systems worldwide.
We audiophiles tend to be rather an extreme bunch.
