I am hi rez producer looking for most accurate NOS dac,money doesnt matter,I can afford anything
Soekris dac chip and Totaldac,these sounds great but I dont care about greatsound,I want truth,maximum bit precise accuracy.... 12-13 14 bit dacs,I love their sound but this is no game,I am producer not hi fi end user,I will use it for mixing and mastering,to hear every little microdetail so I can make consciouss decisions not shooting in dark
right now I see it between Phasure NOS1a and Metrum Pavane,thing is there are two other R2R dac chips that I think might be better than pcm1704 k and metrums Transient modules,problem is these other r2r chips are in oversampling dacs only
AD5791 currently only in Yggdrasil from Schiit,thinking about modifing the Yggyso it accept higher than 192khz pcm and also bypass or put out the oversampling filter.... or even builing AD5791 NOS dac from scratch with best components and powersupply
MSB R2R chips,they sell these separately like OEM,the Rockna Wavedream dac was made using these,I wonder if NOS dac could be made by modifing the wavedream or Signature series

If money is no object I could design you the most accurate NOS DAC. However do you also want dynamic accuracy in addition to static accuracy? If so then that's a whole different kettle of fish - note the AD5791 does not do very well on dynamic accuracy.
listen,what will I write now will probably sound like trolling or bullshiiting/lies but its true
I want to produce unique music that will be most dynamic music in the world,for example 20hz kickdrum that is uncompressed and its like only one cycle long, image a 20hz sine wave that is only one cycle long and is extremly loud compared to rest of music,it comes from total silence and there is only short pause between next infrabass transient assault,need something that would keep up with my insane ideas
it must be world most dynamicaly accurate DAC
so what chip you say is best for dynamics?
You'll probably be happy with a Trinity: Trinity Electronic Design GmbH
Personally, I feel your money would be better spent on a Benchmark and some better speakers.

I listened to Benchmark,I hate it,I much prefer R2R to S/D
Trinity I heard about it,its just 1704 oversampling dac with top quality implementation or did I miss something?
Goobicii,
How large a market do you think there is for your unique music? Or is the projected number of sales as irrelevant as the price of the DAC?

it will be for free,I dont care about sales or popularity,for me music is one of biggest joys life has to offer and I will make it honest,pure without any commercial thinking taking away from it.... it will be 100% uncompressed,I dont care about loudness wars,also it will have very low bass sounds,it will be music for maniacs with high end headphones and speakers not radio/tv
I've been working on getting maximum dynamics from my DACs for a number of years. Are you addressing recording in producing music or only playback? If only playback there's little point in working towards the ultimate dynamics DAC as it will only deliver ultimate dynamics when the recording was made with an ultimate dynamics ADC. ISTM many, perhaps most ADCs today are some way from that goal because they're S-D based.
There's more to getting ultimate dynamics than the chip itself, as the output stage is quite often the limit. Its my belief that TDA1541A is one of the top contenders in the audio world for dynamics but I've not played with it. TDA1387 does very well for dynamics when given a quiet enough power supply and a sympathetic implementation of an output stage.
I will make 100% synthethic music..... ADC problems I dont want to discuss in this thread.So these old 16bit chips are most accurate R2R chips on this planet currently when it comes to dynamics?
thank you for your knowledge,my problem is these are 16,not even 18 bit accurate
what solid state dac with these chips,commercial or diy would you say its best?

I think you are confusing 'accuracy' with precision. A 16bit chip is rarely 16bit accurate.
TDA1541A and TDA1387 aren't R2R chips - R2R chips suffer in terms of dynamics compared to these.
One of the best solid-state implementations of TDA1541A I believe to be Pedja Rogic's 'Audial'. Not had one to listen to myself but the design has a decent pedigree.

wow I thought these are R2R!!! what kind of chip is it then when it isnt sigma delta or r2r
NOS DACs usually run with little or no reconstruction filtering, and sometimes with no compensation for the HF rolloff caused by sample-and-hold output. Hence, by design, they are not accurate - if by accuracy you mean reconstructing the band-limited signal given to the ADC. You can add a good reconstruction filter to a NOS DAC, but high quality brick-wall analogue filters are difficult to implement - which is why oversampling was invented.

For a perfect 20bit DAC the THD (excluding noise) would be roughly -180dB. Compare this with the figure given in the DS.
I explicitly said 'excluding noise' - 120dB is roughly the quantisation noise of 20bits.
Even if you believe the THD should be -120dB, check the datasheet for the actual figure.
