If they can get $5K for that then obviously Soren has created something really good (not that we on here don't know this already!)
Hi Dady, for a three way system after you have digitally separated low, mid and high frequencies, what is you plan to amplify the signals before you feed your loudspeaker drivers with it?
The mass soothes and thus helpful in some places is known, mass inertia law. I too calm sensitive points of my music reproduction system with additional 90Kg weight. However, the stones on the high-end only 5-10 grams of weight and cost more than 100kg of processed granite. As we will surely meet again there Soekris DAC derivatives which will cost 5000€ to 50000€....
the reason you cant use the diy version for oem is because all the vendors dacs would sound almost identical
Lessloss has done something commercially smart
Their first to launch
Simple build an amanero a bipolar supply and a little power treatment and their done
Everyone else will have to be a little different by customising a more barebones oem board

Thats whats so smart their repackaging the dam
Something any novice diyer could do

Let's put it the other way, if one commercial DAC company takes the dam1021 and highly modify before putting into a nice wooden chassis, rather than just make the dam1021 works with minimal configuration and put it into a nice wooden chassis:
-Which way has higher profit margin?
-Can the customers identify the difference without "seeing" the inside?
Be real, it's all about business when we're talking about a profit making business but not a hobby.
In addition, Soren always recommend not to modify the DAC, I think the company just follow the official recommendation. Personally, I found that the factory default sounds great for my rev2 board!
what i said

indeed the best idea for business
the r3 is already good enough to be in the 5k category and probably easily beats them so no design changes are required and best to leave scope for updated models
but just because it's good
does not mean it can't be better
BTW, being the dam mods champion, did you consider upgrading the ladder resistors. This might be one of the most impacting upgrades. I remember somebody saying that after upgrading two (per channel) output filter rsistors the SQ was clearly improved.
It would be great to have and hear dam with recently released z-foil vishay vars SMD version resistors
Then what is the point if you calculate it that way Total DAC is a steal price DAC. Im sure the sound quality with Zfoil will be on another level but at what price? each resistor costing 20 USD so for 200 of them 4000USD alone?It would be great to have and hear dam with recently released z-foil vishay vars SMD version resistors
I think soren should focus more on the resistor quality here if he can source any better.
But like the previous replies I see alot of improvement is needed in the DAM.
Power supplies, Stock filters, and Jitter reduction as after the FPGA the jitter is about in 100ps i guess so no matter how good is the clock the FPGA will add the jitter.
Can't find the price for those:
Texas Components Corporation
Anyways even if they cost 20$ per each (through hole is ~10$ per each) in large quantities it would be cheaper ... I guess. So even 4000USD is still much cheaper than 13000EUR for total dac.
They seems to use a std dam1021.... The OEM version was just because I could, although it has taken me too long time to finish it....
But I have a question soren when you say its a signed magnitude dac then why each sign has 28 resistor + 28 resistor for positive and 28+28 on negative where each 28 is either R or 2R.
Technically isnt it like 14 for positive R and 14 for positive 2R and for negative sign 14 for R and 14 for 2R. Isnt the Dac upsampling in the above case?

It actually is, I'll leave for you to figure out why. Speaks volumes about Theta's engineering competence too btw.
