Neotech NC-P313 vs. Furutech FI-28 Plugs

I don't know anything about the IeGo plugs.  sorry.  I've looked at pictures of the IeGo and the wire clamp mechanism sort of reminds me of Wattgate.  I think you're better off getting Furutech or Neotech.  I love the build quality and design of the Furutech wire clamping.  The Neotech is excellent as well.

I've used Furutech and Neotech.  Oyaide is another good brand, but I've never used them.  They have a palladium plated product, which is interesting, but I don't know how it sound.

I do not recommend using the Cardas plugs because the fold-out casing just rips away with hardly any pressure and you have a plug case that just fallen apart. 

Yes, you're probably right, auxinput. I saw how cheap they were compared to the Neotech and Furutech and was thinking of giving it a go based on price, but then I thought about the usual Chinese quality. 

I saw that it uses the Wattgate terminals, which is a blessing and a curse; it is much easier to terminate, but you have to be careful because they do not grip as tightly as the screw type terminals that most other brands use. 

I wasn't considering Cardas or Oyaide because they don't use conductors with high electrical conductivity. Phosphor Bronze and Beryllium Copper are not that great. 

Phosphor Bronze and Beryllium Copper are copper alloys (probably 92 to 98% copper).  They are actually not that bad - I have used them.  They are significantly better than the low end brass plugs (like Wattgate).  Pure copper is better though.  However, the low conductivity of Rhodium plating doesn't necessarily mean that it performs worse.  Low conductivity is almost like self-damping resistance.  The plating actually helps with two metals mating/touching that aren't actually soldered together (like you find in plugs and interconnects).

The Furutech FI-15 Plus (R) rhodium plugs are probably the "best for the money" at $55 each.  They are actually cheaper than the Neotech gold-plated plugs.

Yes, I was actually originally looking at the FI-15, but you said to stay away from the clam shell design, since it is easy to break. 

The Sonarquest plugs replaced Wattgate, and I can safely say the Wattgate is GARBAGE. 

One of the things that attracted me to the IeGo was the Wattgate-type clamp. It is both a blessing and curse. It makes it very easy to terminate the plug, but it also can be hard to know if the plug is tight, which can lead to it loosening. That being said, I like not having to maneuver the wire around the screw in the screw-type connectors. 

The IeGo connectors are 55/pair for the unplated copper. That's hard to beat. Shipping is $20, from Taiwan though, so I am debating buying those and seeing how they are. 

The Neotech seems like it may be my first choice, as for the money they are hard to beat. To get the high end Furutech seems outrageously expensive, to me at least. 

The Cardas clamshell is very fragile and not well manufactured.  It's almost like "you touch it and it breaks".

The Furutech FI-15 clamshell is actually very durable.  I have actually switched one of these FI-15 between about 5 or 6 different cables before one of the edges actually broke.  A good way to handle it is to have the bottom clamshell completely down while you tighten the clamp screws on the top with the top clamshell open.  The bottom clamshell actually helps hold the unit while you tighten the screws (and then vice versa with the top clamshell).

I don't like the Wattgate clamps as much.  Once you use the Furutech clamps, you will find that it's actually a very good design.  It operates in a similar way to the Wattgate clamps, but it is definitely superior.  You unscrew the clamp and it opens up a space in the hole.  The Furutech clamp actually forces the wire into a curve so that you have more contact surface to the plug conductors.

The IeGo connectors are definitely low cost, but just remember, you get what you pay for.
