What do You mean exactly? As far as I see it just plugs in the 10pin J8 connector directly and is held by the female connector header..
Ah ok pardon I'm slow. There is some extra space provided by the standoffs included with the dac. (I'm talking about the original V1.2 version - but it looks much the same in this respect)
Only few mm's are needed for the U.FL connectors. They are flat

Is this board included with the DAC main board or is sold separately ?
Are you going to provide also the u-fl cables ?
Since it will be mounted in the free space between the dac and the output stage board are there some requirements in terms of height for standoff and J18 connector ?
Yes i will supply the adapter for free if needed.
As Joseph K says: The PCB and u.fl connector will add only 5mm in total to the height of the IDC connector.
The standoff needed between the DAC and Output stage is 18 - 20mm.
For the cables: Hirose 200mm u.fl. cables cost 7,6€ each. You will need three.
The length depends on the position of your RPI + FIFOPI.

Regarding TSSA V1.8
We will stop the production of it and replace it with a board that is build on the design of the Gain modules which is a lot better than the TSSA V1.8 sounding in my ears. So this time it is a JFET Folded cascode design. With balanced input.
It will cost 125€/channel. Have the same assembly holes as the TSSA V1.8
I guess in two weeks time the first batch will be ready

That's TSSA v4 you have, not 1.8 which is a different amplifier
See here for version 1.8

oh yes, thanks
Dac V1.2a
Yeah, I know, and I'm waiting for this new amp! And I'm very excited, I got a parcel from Sonny 😊 Thanks a lot!

Just want to confirm the TSA V1.8 replacement.
I did a quick calculation on it and i want to confirm some features on it.
What it does not have from the MIRAND A1 V1.2
But it comes at a lower pricetag.

I did a quick calculation on it and i want to confirm some features on it.
- Board size : 94x64x41mm
- up to +/-50VDC
- DC servo, 1 trimmer only for Bias current
- Build in undervoltage lockout
- Build in Output DC protection
- SSR output switch just like in the MIRAND A1 V1.2
- Slew rate 40V/usec
- 100Watt@8R
- Balanced input
What it does not have from the MIRAND A1 V1.2
- It does not have the Very high slewrate of 300V/usec
- It does not have Several supply voltage filter sections
- It does not the fine discrete voltage regulator of the A1 V1.2 per rail.
- It is Voltage feedback instead of current feedback
But it comes at a lower pricetag.

Wov!! Great! It is very nice to see Sonny back in good shape and You getting rewarded in your patience!!
Wish all the best to you both!
Datasheet on the DAC board.
OLED and Preamp will follow shortly.
Thanks for thedatasheet.
Where can I find dimensional drawings fo simple front panel (7 segment display)?
I made this frame to easy test everything..
But it also shows how fairly simple the build is... If preamp is kept out, the oled is still connected the same way View attachment 756819
What is the cost of this setup by component?
Thanks,
Robert
Hi coz.
The preamp board 480€
The dac board 428€
The discrete output stage xlr 360€ (can be SE in this setup for 220€ but will provide less thd+n performance compared to xlr)
Oled display 127€
And a powersupply... I use a smps in this case..
So without the smps
Preamp / DAC Setup 1255€ for SE dac or 1395€ for Xlr variant.
DAC Setup 775€ for SE dac or 915€ for Xlr variant.
