Quote: If D6 will be running on 9V batteries the voltage swing will be larger than D12, which runs with 5V Lithium batteries. But until D6 will be officially announced so this is just speculation. D12's USB is 16/44.1 vs D6's 24/96.

Ron, if I have the Topkit for D4, D12 and Supplement Kit for P4 do I still need to purchase the D6 Topkit?

HiFlight, does it means that if I am going to buy P4 there is no need to buy a D12 Topkit as it is already included in the P4 stock opamp rolling kit.
