I am working up making high pass filters for 2 way speakers, for using with subs. My Ayre VX-5 Twenty amp has an input impedance of 2M Ohm - Balanced. Yes, 2 Meeeeelion. I want balanced connections, which means 1M Ohm per leg. If high pass crossing ~80hz, that means a cap of .002uF. I am a novice with this stuff. Any recommendations on a source for very high quality caps in that spec? Places like VH Audio don't appear to carry stuff like that.
Thanks for any help / advice.
