Can you please explain that briefly ? Capacitors inherently have a current vs voltage phase shift. In a band pass network, there may be no phase shift, but then, a band pass network has a coil(s) and capacitor(s).

Nothing to explain, phase shift only occurs in the roll-off region, proper design practice will render the point moot.

I won't hear the CAST in this lifetime, unless I win the Lotto, so should be good

Duelund Coherent Audio are the best.

CAST means 600V rating for tubes applications other users can go with normal ones 100V rating.

No...
CAST means they caps are 'casted'...

You can have 100/200V CAST for XO application and 630V CAST for circuit...

Thanks.

Well, i was a little worried that diverting some car repair $$$ to the purchase of Alexander caps would back fire on me...

Have them in my amp, and oh! boy! was i ever wrong

If they are this good out of the box (on box, just a figure of speech), I can't wait till i get a couple of hundred hours on them

OK about 80 hours on them and they have opened up some, everything about the sound is just correct, instruments and voices have never sounded so much like the real thing, rock solid sound stage... and again just presented correctly

May I know what caps did you use before for the coupling position?
