RE: How do I install Duelund PIO capacitors in Audio note dac

First of all, make sure that ALL the solder is removed from the holes. Do you have solder wick? If not, or even if you do, put a bare piece of copper or tin-coated wire through the hole and apply some heat to get any solder soft enough to lift out with the wire.

When you are absolutely certain that the hole is completely empty, file down the ends of the new leads until they fit into the holes. Be gentle, don't pull on the wire by holding the cap, but hold the wire itself while using a small, fine file, and don't make any sharp edges, tapering the wire down until it's thin enough to fit. I would NOT attempt to enlarge the holes unless you have experience with that and know what you're doing. It is easy to lift the pad or damage traces with a drill unless you go REAL easy. If the holes are through-plated, as many are, drilling will remove the plating. In that case, you must solder on both sides of the board.

Splicing leads can be tricky or nearly impossible to do a neat, secure job, and may introduce enough distortion to negate whatever improvement the new caps make.

A final option is to not connect the new caps to the board at all, but solder the leads directly to whatever parts the PCB traces lead to. This can be done on either side of the board. First you should slip or wrap some insulating material over the cap leads. Be careful of excessively heating the parts or existing solder joints.

When you're done soldering, make sure you secure the body of the cap somehow so it doesn't flop around or vibrate.
