I think quite a few people have missed the detail that you haven’t made any upgrades in a year. A year is enough time living with a system to know what is lacking. It is quite possible your bookshelf speakers perform very well for their price tag, and that you would need to upgrade massively to hear enough improvement to feel it was worth any expense at all. If that’s what you find as you check out speakers, I would suggest again that you may get a lot of the improvement you are looking for by adding a subwoofer to fill in where your speakers leave off. You also may get more placement flexibility than if you were trying to rearrange the room for tower speakers. About a year ago, I went from bookshelf to floorstanding speakers thinking I could get basically full frequency response without a subwoofer. The speaker upgrade was a massive improvement, no question. A few months ago, though, I added a subwoofer to the system, and it was astounding how much fuller everything sounded immediately. Had I added the subwoofer first, I think it’s possible I would still be holding off on upgrading the main speakers. Regarding your “test” policy question, do you mean they would not do a demo in store for you? Or just that nothing leaves the store without payment? I am of the understanding in-store demos are a standard part of the business, so I’d probably be trying to find another dealer if they won’t do that for you. If they are just saying you can’t do an in-home audition free of charge, then that is typical.
