Bullot, of course its a matter of personal taste. However, having said that - it is typically recognized that high or treble center should be at ear level -- I believe this to be the basis of elevating speakers and I too, find this practice to be best, as I find that ear level highs/treble center pulls the sweet spot into better focus. Also, I find this to be a more natural sound, as I compare and judge my system to natural live music - as you know, most live venues place the players and orchestra/band on a elevated platform or stage - thus, listening acoustically the sound is centered above your seated position or even at amplified concerts the speakers are typically placed up high, often even hanging from the ceiling. Thus, my placement and many others. Of course, I have always started my placement ritual with the speakers on the floor but in 100% of my home experience I have eventually elevated my speakers to highs/treble center at ear level or sometimes just above (depending on the speaker). Again, my experience and taste...
Islandmandan, My Canterbury's are beginning to open up but they still have a ways to go... Unfortunately, I am spending a fair amount of time away from home now due to work and the results of our limping economy, thus, have been only able to enjoy the music on weekends and limited times. But, I have to say I do appreciate the sound more and more - its a real treat to come home to.
On a side note; if anyone is still interested, the buy I thought I had on the Quads did not follow through and thus, they are still for sale - I did remove them from the bases and box them up in factory condition. Its a real shame that high end gear is moving so extremely slow now... its a real buyers market
