You don't have to spend anywhere near $10k to get fantastic speakers.

At the $10k level we are talking car-priced audio jewelry.

Personally I am a huge fan of RBH out of Utah. They have build speakers for other well known brands with much higher pricetags for decades. Their own lines are very very good, even their budget impression series bookshelves sound very good.

I have their previous gen higher end speakers, the sx-6300 towers for my mains, Se-441 for my center channel and se-41 for my surrounds, and I am very happy with them
