Make sure you don't fill in the bass port holes with paint or they will be a nightmare to tune. Learned that one the hard way.

On a totally different note, I'd really appreciate some help with the Hirose connectors.
I've seen the note included on the PDF file with the exploded view of the cups, indicating that Pin # 1 on the receptacle is for the signal, while Pin # 2 is for the ground.
Would it be possible to get confirmation that the PIN numbers are intended as viewed from the internal side of the Hirose connector, where the internal wires will be soldered?
Also, I'd be grateful if someone could shed som light on the correct pinouts for the plugs on the headphone cable as well.
Unfortunately, I have zero experience with the Hirose connectors, so I'm really afraid I could end up mixing the scheme up, thus rendering the connection between the cable and the headphone null! :-/
Many thanks for any indications on the above!
I'm going to receive my cups very soon. I am also working on a thunderpants mod for my t50rps. I'm busy right now, so in the coming months I will post a review of both and a comparison.
Another question I have is what would be a good amp to drive the alphas? I'm leaning towards the Project Ember 2, Beezar Torpedo 1, Schiit Asgard 2 and Valhalla, but I can't decide.
Many thanks for the info!
I'm waiting for the Hirose receptacles to be delivered. Once received, I will take a macro shot of the connector and share the photo on this thread, in case it could be useful to others in the future.
Meanwhile, I'd like to ask one more question:
I guess pin #1 and pin #2 on the receptacles (female connector) are mirrored on the cable plugs accordingly, so that both pins on the two connectors will match when the cable is plugged into the headphone jacks, right? Or should the pinouts on the two connectors be figured out properly when soldering the wires to the receptacle and plugs (i.e. is Pin#1 the signal/positive and Pin#2 the ground/negative on both connectors, or should the orientation of the two connectors be considered and reverse the pins on one of the two accordingly?).
I'd consider a Gustard H10 as well.
Amp choice is kinda personal and everyone will have a different answer. They'll all be correct.
Personally:
Considering sound only:
Torpedo>Ember>Valhalla>Gustard>Asgard.
Disclaimer: I've never heard a gustard though, so I'm going straight off secondhand accounts.
Things to consider:
Valhalla is an OTL, so while it'll work and sound good, it really isn't an ideal match like the Ember and Torpedo.
The Torpedo is awesome, but it's much more expensive than the rest. (Unless you assemble it yourself)
The Ember can be bought as a kit, but buying it assembled only adds a small markup.
Final fit and finish will put the Torpedo a distant last. The Ember is slightly behind the Schiits and Gustard.
The Torpedo form factor is really crappy! It doesn't fit well on a desk. All the rest are fairly small and convenient.
For straight ease, the Gustard and Asgard are ahead of the others. If you like to tinker (and you probably do since you're reading this thread) the Torpedo offers the most customization options during the build and the Ember offers the most after the build.
If you want to include tube rolling as part of your Open Alpha tuning, the Ember has by far the most options. (Even FrankenEmber)
The pins are numbered on the solder side. Depending on your, um, maturity level, you will need to use a magnifier to see the numbers and to solder the wires. I wrote up something on the DIY cables thread about the pinouts of MrSpeakers connectors and some others: http://www.head-fi.org/t/676402/diy-cable-questions-and-comments-thread/6045#post_12982540
I've received the Hirose receptacle today (HR10A-7R-4S).
I've taken out my camera and macro lens and took a picture of the connector from the back (pins side):
I was quite surprised to see such an offset between the pins and the reference numbers! Quite confusing!
Am I right in my understanding that the order of the pins is the following?
1 4
2 3
Many thanks again!
Now, this is really strange!
Sorry for double checking... but are you looking at an Hirose female or male connector?
If yours is a male connector, then I guess it's normal that the pinouts are reversed/mirrored when compared to mine.
It should be a design feature, in order for each pin on a female connector to match the corresponding pin number on the male connector... if your connector is a male one, we have a definitive answer!
Edit: To clarify, the photo I've posted before is showing one of the two female receptacles (HR10A-7R-4S), the ones to be mounted on the headphone cups.
I don't have the part that attaches to the headphones. The pinout should match the HR10A-7J-4S. So long as it matches the connector on the end of the cable, it should be fine.
