In Reply to: RE: Best sounding IC sockets for op amps posted by Lew on February 24, 2016 at 19:30:00
I agree on soldering but I think he wants to easily switch them to compare.

But is there anyone in the world or on this forum who has actually "listened" to IC sockets? I would put a smidgeon of contact enhancer on each pin and then just go with a socket that appears to be well made with good conductors. End of story.
If comparing IC sockets have not been done yet I suggest that a group test a few different kinds in a blind test and get back to me. This could be big, or maybe even Huuuuge. Maybe Donald could arrange it. Looks like gold with your suggestion of a contact enhancer to protect the contact is the way to go. Tweaker
You can bet your life he would use gold sockets, too.
True. And I bet it's 7 9's OFG.

I suggest the group start with a quick look at the specs. GP Turned Pin sockets were reckoned to be best by a margin 40-odd years ago (when I first used them) and AFAIK still are. See e.g. figs re capacitance.
Best option, at least theoretically, is to solder devices to the board but I defy anyone, however "blind" the test, to detect the difference between a TP socket and a solder joint. It could indeed be Huuuuge but OTOH it could be treeevial.

I don't know, adding another connection via a cheap socket? Like I say I don't know but if you gave me money to bet Is say adding sockets vs direct to the board would be a negative.

The OP asked if anyone had compared sockets and sound quality. No, I haven't because I don't use anything other than turned-pin sockets in any critical application or DIY project. Though typically more expensive than other types (whose names I forget), they provide reliable connections for at least a couple of hundred re-insertions as well as low resistance and stray capacitance.
Anyone planning to try different op-amps in a circuit is being a bit silly if he/she doesn't use sockets for them. That aside, soldering them in is probably fine.
Provided, of course, you never need to fault-find the circuit and you're confident that soldering doesn't degrade the device in any way. I haven't listened out for that either.
An extra connection is always or almost always negative. I wanted to do some op amp rolling but it looks like it might be risky in my particular situation. Tweaker
I doubt anyone has compared sockets. There is also no gear that uses them. The OP always tries to leave no stone unturned IMO and sometimes takes things too far.
