"Well since you have stated before that it all sounds the same, I guess it could be anything from Best Buy for you."
Maybe, maybe not, but it does not answer the question. I asked YOU, where does 'quality equipment' begin?
""Polk Lsi15. I have had the urge to 'upgrade' for 9 years. But there is nothing out there that would be an 'upgrade'"
Given my space and values, this is true. it also could be true in an absolute sense. I do not equate price and size with with sound quality. Now, there may be many fine speakers in the polk's class / price range, but that does not mean they would be upgrades. They may not be as good, or just as good. the 'monster' speakers are not considered due to size / appearance reasons. So saying for instance, that the Wilson Maxx is a better speaker, has no meaning to me. That's like saying a Formula 1 car is better than my fusion. It's too big and costly for me, and NO ONE has ever said it was the PERFECT speaker. I would rather have his and her S classes.
And I was not the first to say it all sounds the same. The FOUNDERS of this hobby said so. And they were true hobbyists. Made their system themselves. If I mentioned their names it would cause foaming at the mouth and howling throughout the site. I am sure you know your audio history, so you already know of them.
