I am currently the proud owner of an Arcam A19 and CD73 hooked up to some B&W 606s. I love the standmounters, but I notice when playing some pop/rock music that on occasion the bass player's rhythm drops a little as if there isn't quite enough oomph in the speakers to go low enough to reproduce all of the bassline properly. I was thinking of adding a B&W ASW08 sub as this is a good sonic and aesthetic match for the standmounters and its a 30m2 room only. My question is what's the best way to connect the sub, do I 1) connect to the A19's speaker terminals with spade connections (the 606's are connected with bananas) to the subs speaker terminals, 2) connect a twin set of RCAs direct from the CD player to the subs RCAs, or 3) a sub RCA from the coax of the cd player to the sub's coax? Is there another (better) way? Are there any sound timing or integration issues with any of the methods I've suggested? Thanks guys and gals
