i had a chance to go listen to the Spire's yesterday. I was actually disappointed. They did some things great, vocals were very upfront but so was everything else. They sounded interesting but not real. It seemed like the drums, guitar everything was on an even plane about a foot in front of the speaker. Also the sound off axis was a dramatic difference much more pronounced than the folks on the Logan forum care to admit. It was set up properly using an Ayre front end and they did sound good, just not what i was expecting.
What i was impressed with was the new 804 diamonds, they looked tiny in comparison but sounded just as big as the Spires. In fact they actually imaged higher and seemed more disconnected from speakers themselves. The bass was not as powerful but i think a sub could cure this. I had never thought about the 804ds but they are top on my list now. Would a sub cure the lack of slam?
