If your are talking to me, I already own HE6 and HD800.
And at least 20 other dynamic headphones.
Electrostats... I can't count that high.
lil-knight will be selling the boards. all the boards
i'm going to change the on board heatsink version of the SS dynahi to
take the thatcorp bipolar input chip because i'm tired of waiting for the
here is the onboard version in progress
all current manufacture onsemi parts replace the almost impossible
to find old parts.
The ksa5 is a sweet amp. Very quiet, great for iems, essentially great
for everything unless you want really loud. At +/-22 volt rails it
is voltage limited. Dynahi is +/-30 volt rails, so larger voltage swing
and ssdynahi doubles that voltage swing.
On the diy ksa5, if you want to change the servo opamp to opa445
(and same on the power supply) then you can bump the rails to +/-30.
All the parts are minimum 80v rated, so no problem.

Its Krell. It gets hot. Not FPB600 style hot, but plenty hot.
At least you can hold onto the heatsinks. Its pure class A down to 4 ohms.
