super V/I converter with LL 1684

Hello, I have doubts about super v / i converter with LL 1684 if it can equip my power amplifiers, there's only 2 volts at the end of the output. I have a Holton hpanvx 300 r2, and hpanvx 500 r1 in paralell in each cabinet, will super converter with LL 1684 be able to make enough output voltage for my amps.
I hope someone here can help me.
 
Parallel amps

I drive an amp and a subwoofer (class d amp inside most likely) in parallel from the output of my LL1684s. The amp is 100kohm input , however, I don't know what the input impediance of the subwoofer is. Using no preamp, direct out to transformers of a buffalo iiise.

OK, let me nervously join this GB for output stage only ...
... postition 12 (edbk) withdrew from the GB, so I will slip all numbers up, and join at position 30.

Hi Quanghao,

I already own the first version of the DAC-END, it's great.
I am on the list for just the new output stage. Can you tell me what I need if I want to change to the LL1684 transformer output stage? Can I just buy the LL1684 transformer or do I need to make additional modifications?

You need to remove the output jump to convert in voltage mode and connect the LL1684, there is a pcb with connectors available from Quanghao
 
Updated list, since I'll just need the LL1684 output board.
Removed myself from this list and now position 6 is available.
