FW F4 done but...

After quite a long time the F4 got to and end and made it to my place, very nice build off of the guy who made it for me, I will some day take pics to show the dual mono arrangement with custom filtering, very well done but...

But it doesn't do it with my JBL L220 (90dbW/m) and Audio Research SP9, with my other power amp (dual KT88) the volume knob to hour 11 at the most, now all the way to the max and still not enough pressure, I will try to move the line input to another source on the pre to see if there is a little more gain but to this moment in time I am quite disappointed.

I know the AR SP9 swings about 20/21db on the outputs, I am collecting stuff to build a BA-3 preamp with 30V to achieve a little more gain than the SP9, I left the thread a while ago as I am in my very busy season so I can't recall correct gain figures but would that be enough to not make me blame myself for my F4 decision vs the KT88?

Grazie
