The TRRS aren't hard to find, but quality ones are. The one you show is magnetic. I have the one shown, which is the most readily available but it is nickel plated and as mentioned, magnetic, which man TRS/mini plugs are.

Every single resistor in this amp is magnetic!

I don't know if those are or are not but I have SM resistors right here that are not and I just checked one of Rays amps and the ones I checked are not magnetic.

How are you testing? Care to post some pictures?

The reason I say this is that I have talked with most if not all manufacturers of SMD resistors and they cannot provide a non-magnetic SMD resistor due to the nickel barrier plating on their terminals that prevent leaching during the soldering process. Just not feasible.

Some nickel but the TRRS shown has a solid steel support. I tested with a super duper magnet that I use. If they have any it is very, very little and nothing like the solid steel support of the TRRS shown. Hey, it doesn't matter, what ever works is fine with me. I am back to listening to music. :^)

The red nail varnish is obviously an anti-magnetic coating. Finally I've figured out it's purpose

not to hijack

Not to hijack...but because Ray is a paying MOT anything related to his amps can be posted anywhere. And in defense of my buddy Jam, he is at the heart of these boards...THANK You for posting this!

I too am curious about the proprietary nature of the connector will others use this or other connectors, Im sure many are concerned with the universality

If your relationship with Ray Samuels is this tight (you're certainly a proliferate mouthpiece) then threads like this need to be considered under the MOT rules.

Personally, I think that what you're posting here skips around the rules and needs to be curtailed.

John, do you have any inside info on the release day? I'm amp less now...

What I find exciting about the little amp is that it appears with the greater voltage swing it will now have IEM's or headphones, like the HD600 can be used. This would mean that you can easily listen to balanced outside of a home or other "home" amp setup. Should prove to be very interesting.

The pictures are nice John, any news on the amps specs also the cost.

The potential amp definitely is interesting and innovative for IEMs. As for driving full-sized balanced cans well, I'll believe it when I hear it.

EDIT: Jamato, how does it sound so far?

Some questions & comments

1. Does this amp convert a single-ended source input into a true balanced drive output?

2. Regarding the resistors in the output stage, do IEMs really require much dampening? Since this amp is first & foremost designed for IEMs, I would think the requirement of coupling higher-voltage balanced output with a very low noise-floor is more important a design consideration, no?

Inevitably, there will be those that plug their balanced HDxxx's into this thing using the shown adapter. Maybe it will work fine, perhaps not so much - who knows at this point. But this is undoubtedly where the discussions (& criticisms) about this amp will go. I don't think any engineering design can be all things to all people (or headphones), so I hope expectations are tempered accordingly.

All that being said, I still have to wonder if IEMs really require a balanced output amp at all. I know there are people who have already balanced their Etymotic ER4's, claiming real benefits. I have no doubt that anyone who can afford JH13's can also afford a super-duper, balanced, after-market cable, and their money & wallet will soon be parted. Ray is simply catering to this portion of his customer-base.

some fair points, but why does it need to be a super duper balanced cable? the connectors are available, you can simply reterminate a stock cable. all the same I do indeed find that my JH13 sound great balanced our of my buffalo32. what i'm interested in is the battery in this, because if its just the same voltage split in half then there isnt any extra swing at all
