Yep 6 DCs are the most you're ever going to need. But for sonars, eventually you will want a few more than 6 since DDs and most CLs have 3 slots, and sonars give more ASW compared to their respective DC equivalent, making them the better choice for equipping in the 3rd slot.

But getting extra sonars isn't as important as getting the first 6 of each, and you'd probably want to focus on getting better planes or radars before getting extra sonars anyway :v
