Hi fellow builders
I'm after nice, practicable, affordable connectors for my amp- and preamp-projects... that is, signal-connections as in "wire-board" as well as "board-board".
There are plenty at the usual suppliers, but I'm a bit lost because of the many variables to look for, and a lack of relevant experience?
obviously important are
- connection-quality
- signal-integrity
- ease of use
- price & availability
of course, if there was something that is looking good it'd be all the better.
thank you!

If there is no need in some determined impedance (for example 50 Ohm for high-frequency applications), then for wire-board connection type I use usual popular ones. For example the cheapest 2.5 (2.54) mm one I think is NX2500 series: nx2500-02sms ( A2501WV-2P1 ) for PCB. NX2501-02PFS is Female wire part.

For crimp connectors I normally use JSTs (XH for signal and VH for power/speaker levels) there is a gold-plated version as well if that makes a difference. For wire-board connectors I use screw terminals of various sorts - either from Mouser or Reichelt.
I like Molex or JST connectors. Easy to work with. I don't crimp, just solder them, after tweezing them a bit with pliers, or they don't fit on the connector housing.
On newer digital amp stuff they use flat cables, not easy to work with & You are limited to standard length sizes. Not suited for many connections / disconnections.
Flat-cable like those used for old PATA HDDs & Floppy disks is also an alternative and was also used on many gear years ago.
You cut the wire and assemble the cable on a Vise for example.

Reichelt has clones of the KK serie which work ok. See the "pss" and "psk" connectors. The crimping tool isn't expensive either (18€).
If you do use Molex connectors, DON'T use the tin-plated pins---get the GOLD-plated ones. They're more expensive, but years down the road, you'll be glad you did!
Molex KK 100 for signal is OK. I never experienced trouble with the non gold plated versions but I heard of trouble with the tinned version long ago. Maybe it was solved as I use these a lot and they never fail. I have the original crimp tool and it is an easy job to crimp the connectors.
For power and higher currents: Phoenix MKDSN.
