I was in the A/V store today - ready to purchase Paradigm Reference v3.0 (1) cc570, (2) Studio 60's, (3) SA15's or possibly CS60R's for surround sound. I had heard thru the grapevine that v4.0 was coming out. I then saw the catalog for the Reference Series v4.0 in the store. I asked the salesman about it - he had no idea that it was coming out. He then called the Paradigm rep and told me (a) that the new v4.0 will be out in Jan 07, and (b) the only change is with the "cross-over". Being in a home (newly constructed), with absolutely no rush, would you recommend waiting for the v4.0 speakers ? I have no idea - as I'm sure the prices will go up.
