Morethanall connectors not in stock but I submitted an inquiry. It sounds like they are an OEM looking for large quantities so may not get a good answer. For DIY, JST/Molex/etc and standard panel mount jacks are just fine.

Do we have an option to get four more inputs? What would be the consequence of making a pin header to plug in a second tier daughtercard of inputs above the ones on the board?

I think if JPS64 designed a new input selector panel with 8inputs it could use same header pin cable. Otherwise, I don’t see how what you say could work. Maybe draw a schematic or redline the existence MB schematic?

If anyone can find deals on the special RCA jacks that would be appreciated. They are currently circa $9ea from mainstream dealers. Actually, I am having a hard time finding them.
I couldn't pass up the opportunity for some late night eBay / AliExpress sleuthing...

From what I can tell from comparing the morethanall.com and Hifi Collective CAD, these appear to be the same connectors as the much more readily available right-angle mounted jacks.

The best CAD of the right-angle variant I could find is on AliExpress at Taiwan GIGABAD plate welding BNC turntable DAC decoder digital coaxial input and output PCB instal special copper RCA socket-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group.

Looking at the CAD and the pictures on that page, it appears that it is only a matter of bending the pins straight and repositioning the pins from the bottom holes to the rear holes (I've see pictures with the rear holes both drilled and not drilled). This of course assumes that the pins are just press fit, but I would be surprised if they were not.

The right-angle version are available at around $2.66 each: Taiwan-made gold-plated RCA turntable DAC decoder digital coaxial PCB board sock | eBay. Given the price difference, it might be worth giving it a DIY try.

Default Using on main system now

I connected the Aksa Lender preamp to my new Pass Aleph J amp that I just finished building. The Aleph J is driving my ScanSpeak 10F/8424 & Dayton RS225-8 FAST speakers (fitted with transient perfect XO). The combination sounds amazingly dynamic and lifelike. Super clarity - so yes, the choice of preamp makes a difference with some power amplifiers. I will listen long term now. Initial impressions from the Eric Clapton "Unplugged" CD is very very good. That recording has a very high dynamic range and is ambient recorded with minimal post-production I think. Anyhow, I am quite certain that you will all be very pleased and blown away by the sound quality of the preamp.

I just saw mention of the OEM (AEC connectors), looking at the drawings available on their site, it seems even more likely that they are the same product, just configured differently: straight vs. right-angle.
