Two different setups, the mancave with the A7s has an acoustically treated wall behind my chair, the bedroom has none beyond what my futon offers. The A7s have .22 and .68 on all the caps, the 604s have .68 on two caps of the four caps. Also they have different drivers, 802/515, 808/416, can't make a direct comparison, although the response of both setups has been greatly improved by the addition of the Russian Teflon caps.
PS Also wanted to add that the caps are a fantastic value for what they do, better caps out there but it will really cost you to surpass these caps.
