I'm sure your right there. But as things stand I'm fully pleased with my 5 JBL 3600's bed setup and short of some catastrophe I'm hoping it will take me to the grave.If you are really interested, give it few more years, you will be able to find yourself a great deal on the used market.
At 75 my hearing isn't very "golden" any more, if it ever was.
After working with DRC, REW, etc; the integration with my 2 SVS SB-2000 subs and 4 SVS Prime Elevation overheads sounds quite linear and natural to me.
Most every evening when I throw on some high definition SOTA recording, the rig as it stands continues to amaze me with the listening experience it delivers.
YMMV
