Okay, maybe it is "elephantitis of the placebo" with these HUGE caps in here now...but the difference between the Super 7 and DAC1 HPA seems to be much more pronounced after cap replacement surgery.


I'll spend more time on more occasions, but the Jantzen 0.1 Silvers/Jantzen 10 Superiors seem to extend the bass and "sweeten everything" by making the stage bigger and also taking some of the "digititus treblitis" out of the DAC1 feed...overall a very worthy improvement on top of the tube combo I am digging ATM.

Definitely seems "sweeter/more natural" and closer to the "magic" that I have been chasing since hearing purrin's PWD>BA>800 rig.  I can turn this thing up now.     


Acclimating to the difference, it can sound a little "slower" on a couple of tracks such as David Gilmour's On An Island at first, but I'm fine forsaking the more "forward/edgy" sound of the DAC1>HD800 that seems "faster" for the better DAC1>Modded S7>800 presentation.
Thanks, Anaxilus for the cap-rolling and sharing of notes.   


And thanks also to particleman14 for the help in replacing "Tic Tac" sized caps with the "Coke cans".


(Don't try to mount the 10uf caps to the PCB.  Secure the big caps to the bottom of the case and then run extended leads to the PCB that's mounted to the top plate.  The red caps in the photo of this thread are not the red Jantzen Superior caps which are much larger and you ain't gonna fit them on the PCB. )
