Heads-up for people with I2S transmission issues:

Twisted Pear offers a Teleporter module which converts I2S to LVDS (low voltage differential signaling) and back again at the receive end. They say it's good up to 100 feet (30 meters).

like a riddle So are you going to lay this panel horizontally onto something?
What you are looking at are the three assembled top plates. There will be a surrounding
walnut frame and all in/outputs will be on the left and right sides, Najda to the right. All
power inlets will be on the back. So yes, it will lay like this on/in something.
Like most tubeamps are built, sort of.

Not yet designed, I'll wait until experiments with Oled or VFD are done to select which one I'll choose.

Ah yes that barsteward as was at Scalford show.

Would be easy peasy now with two setups and flick between with the remote using Najda

+1

OLED would be very nice and also VFD has a pretty cool retro look to it.

Backlit LCD reminds me of the office printer. Sorry.

I'm busy doing my amps so Najda is on the backburner for a little while!

Perhaps I should explain the Strain gauge cart is not the barsteward, but the fact that one output is out of phase from it. Only way to correct this is to reverse polarity on one bank of speakers = swap 5 cables for my system. This we did many times on the day as we played Coco's Voyd / strain gauge cart TT and digital sources... As said, Najda solve this elegantly.

A possible (and economical) substitute to the 5 navigation push-buttons.

However I couldn't find anywhere a proper cap (cross shaped would be great!)

Nick,
I would vote for an 8-ch expansion board with DAC and volume that can take inputs from the I2S or SPDIF. This would give the ability to use the 7.1 output of something like the Oppo 93 + Vanity 93. The Najda used for the R & L main speakers with up to 5 ch each. Then the other 5.1 ch can go to the expansion board for DAC and volume control. One would add additional Najdas if more active multi-way speakers were wanted. The critical part is that all volume chips would need to be in sync.
