High pass filter capacitors


I’m making a high pass filter between my preamp and amplifier. This will be on XLR Interconnects. I need a .047 uf value . 
Looking for recommendations on what capacitor to use to have a good quality filter. I don’t want to spend lots of money on a new preamp and trash it with low quality caps. I also don’t want to spend $300 per cap if it’s not necessary.

In this range of capacitors, there are a number of excellent brands of caps for far less than $300.

Audyn TruCopper, and even some excellent Duelund models like this one.

I strongly recommend you practice however using like $2 poly caps first, just to make sure you have the right values and wiring.

Also, I think Parts Express has some modular XLR adapters.  They are like M to F adapters but you can shove little parts inside. Perfect for this type of prototyping.

     It's been decades, but- when I needed high quality, small value caps, for doing exactly what you are (using a Placette and/or Dahlquist DQ-LP1): Michael Percy was my go-to, for the best parts available.

                    He also offered a wealth of valuable information.

                            Can't even swear if he's still in business.

                                                     BUT:
