I tried three pairs last summer and chose the PSB CS1001 $550 due to its consistently appealing sound no matter the quality of the recording, level of detail and accuracy, and ability to produce satisfyingly deep bass. Excellent build quality to match the sound.
The Polk Audio Atrium 7 $499 (sale price) was a close runner-up. It played louder, but was a little more harsh with treble when playing poor studio recorded discs. Excellent build quality as well.
The Axiom Algonquin $378 was the worst speaker that I have ever owned. The build quality was horrible compared to the other two models and sound quality was average at best. This is the worst speaker I have ever owned with the exception (maybe) of the Sanyo rack system I owned as a kid.
All of the forementioned employ one inch tweeters, six point five inch mid/woofers, though different materials were used in the drivers.
Playback components involve a PC storing music files connected to AV Receiver with network audio and control, and multi-zone feature to send power to the speaker. Though the Receiver can be used as the player sending audio files over the Ethernet connection, I prefer to use the PC as the player because of the much superior software features. A small netbook pc is used as the controller: allowing remote control of Receiver volume and input selection, and control of the PC's desktop functions.
My experiences are detailed in a thread in this forum, if you want more details.
