Get a couple of these to make some cables for a home studio.
First of all, I like the size of the shell and its weight - it's lighter, narrower and a bit shorter, relatively to the Neutrik NP-style plugs. That makes Amphenol plugs ideal for a studio usage with a bunch of tight-placed input jacks and for a long-term applications, where you need to set and forget it for a long periods of time, i.e. in a patchbays or for connection studio monitors to your soundcard. Besides that, the lighter weight creates less stress on the input sockets, especially if it stays constantly plugged-in. But in a live setup and situations, I think you can found the smaller shell of these plugs a little less handy, then accustomed bigger-sized Neutriks.
The second - these plugs are really pleasure to solder! To be honest, much, much easier, then, again, the aforementioned Neutriks. Amphenols haven't required any additional treatment - just standard applying bit of a solder to the contact plates and tinkering the cable wires - and that's all!
The only downside, that I have noticed - one of the two plugs I've bought have slightly different radius of the tip and sleeve parts. When plugging in a TRS jack input, it feels way more stiffer, then another, and requires more power to take it out of socket. So it seems like an inconsistent quality or a lack of the quality control.
In terms of reliability, I can't say much, because at this moment I have not enough amount of these plugs to make any noteworthy statement. But they seem and feel pretty sturdy.
All in all, considering the price, I definitely would recommend these plugs primarily for using in a studio setup or in applications, where you don't need to reconnect them every day and every hour.
