I personally am a fan of KEF speakers. They are very clean sounding with excellent reproduction capabilities. The "Q' line is their lower end but blow blow away speakers 2 and 3 times their price. As they just released a new series of "Q" speakers many of the previous line are on sale directly from KEF. Crutchfield, Amazon & Best Buy have them for the same price with free shipping. The Q 350 is a Stand speaker that consistently gets excellent reviews. Their tower speakers are the 550, 750 & 950. If you can spring for 950's go for it. I have the 550s with a KEF Kube 10" sub. You really won't need a sub with the 750s & the 950s sound like you are in a concert hall.
I also think the higher end lines of POLK are great sounding speakers for the price, but all things being equal the KEFs are audiophile quality and a great bargain at the reduced prices.
