does one hook up Electrostats to a Priimaluna HP Integrated......?

The only thing I Can come up with is use the output from my Blu Node digital out and connect to a Schiit DAC (for example) and then feed into the electrostatic amp......anybody?

i am considering the Koss ESP/95X any opinions. In this situation there is no Primaluna.....sad but True!

Forgive the title typo, on the iPadĀ 
You are talking headphones, not speakers? :)

Yes, the DAC can feed your ES amp directly.
