Before considering the CS2's, bear in mind that yoou need 4 channels of amplification so if you only have an integrated amp you would have to add in the cost of a pre amp and power amps. Also the add in the cost of XLR cables and possibly additional Speaker cables.
The CS2's take a very long time to break in, but once they have they disappear unlike any speaker I have heard. But they do need a minimum of 5ft from the backwall to start singing.
One thing I have noticed, they go deep, organ music makes the floor vibrate but they don't do Reggae music very well. Strange that.
Just for the record, my system is vinyl and I am hearing more from the recordings with this setup even with the analogue-digital-analogue conversion.
