Hi David, Yes I have the CCS boards, I'm about to order more shunt regs for each board, hopefully they won't take too long to arrive.
I've already built the Buffer board, just waiting for this PSU to arrive Kubota low noise regulator full blown version kit !! | eBay
Your right, it would make perfect sense to build the four board DAC, then test it with the buffer board to see whats what.
Thanks for the pointers
Any chance of some reference photos for your 11-Stack build?
Why did you choose 11 but not 12?
I am just about to order another eight shunt regs from Tent Labs which will cost me 345.82 Euro
Sorry if this has been discussed before but has anyone compared the differences between Salas Shunts and Tent Shunt supplies?
Am I correct in thinking the Salas shunts are cheaper?
Thanks!

The Salas are cheaper, but you have to calculate the component's value for your desired voltage and load, source and stuff them yourself.
But as you can use only one for analog for example, it's way cheaper !
By the way, did you remember the volume discount in your calculation ?
Belleson have a pretty decent volume discount, but as nobody tested them againts shunts, they aren't popular.

Hi G600 , I did wonder about volume discount, but wasn't sure if that was something on offer, I'll email Guido now to see what the total cost would be.
If buying Salas shunts means running calculations myself then I would be way out of my depth.
Oh how i would love to have enough space in my head to learn about Ohms law. 🙁 When I retire I plan to do an awful lot of reading, but I have 25 years ahead of me yet of running a business 🙂
Hi Chanh,
As you can see from the photo I could not get any more stacks into the case if I am to keep the USB option.
Later on in the year I would like to remove the USB board and go to 16 stacks as I am still only listening to 44.1 Red book ...

Pricing & warrantee
All versions € 32.77 each ex VAT, € 39 each incl. VAT. All ex shipping cost. A 5-pack is priced at € 147.06 ! ex VAT, € 175 each incl. VAT. All ex shipping cost. All regs come fully assembled and tested with a 5-year full warrantee, assumed they are mounted and used according instructions.
Hi Sovereign
Don't want to poopoo the Tentlabs shunt regs, but i ordered some a few months ago and they arrived with components missing and noone at tentlabs would answer my emails. Lucckily someone on here helped me out (sorry i forget who) but they still measure 8.3v instead of 8v. I'm sure yours will be fine but maybe check them over when they arrive.

Hi all - 1st post in this thread.
Looking at building a 4 board DDAC but so much info and choices here I'd appreciate some guidance and experience to inform the best choice for me. Here are some of the questions I have:
1. I want a balanced output (will go through RelaixedSMD pre initially - eventually perhaps will use a TVC), do I need output capacitors or transformer? I think not - just connect +ve and -Ve outputs to balanced output and leave ground not connected to output xlrs?
2. I want to fit my build in a 2U case. Space-wise I can't fit 4 boards tall - but I can fit 2+2 next to each other. Is it essential to keep the input wires short or equal length between boards? or, given the length of wires inside the case are only a few cm, can I be confident in using a 2+2 arrangement?

One last question, some of you have shunt regs on the main board, does that make a significant difference ?
Thanks !
Thanks !
Very nice there. Two things I will recommend you doing prior to 16-boards upgrade are doing the raw choke input power supply and BBB with sync clocking i2s direct.
For that many boards, your doede ps will run extremely hot. Why not try to bypass the all the 0.1-Ohm filter resistors and the fuse. Relisten and may be you can hear better transparency, better bass and most of all timing/rhythm/phase are more precise. Alternatively, a choke can be introduced in the absence of R1 with the above mentioned. I found great result while experimented with it previously. Note-endure your choke rating is conservatively accommodate the power demands from your DAC.
Sorry if I talk too much...!?
I really found it hard to understand why you guys are so obsessed with TentShunt? Doede carried out an experiment and reported back many posts back said on digital size, TentShunt are a waste of investment.
you are right! If one is incompetently flying blind then a fuse in place no doubts an idiot proof! 😉
