Still with this problems, i could listen music easily, because feeling is natural. For es or ak dacs i couldnt say that.

A more natural sound
Yes I Totally agree
In fact once I've had a taste for a more natural (realistic) sound I am finding I can't go back to 'ordinary' DACs
Even with the noise - which still is a problem the sound is better than that achieved by most DACs
In fact I was so impressed with the sound I thought it could have been me and it was somehow a more 'coloured' sound that I was enjoying - so I set up my system like so:
A vinyl LP playing Cassandra Wilson -Travelling Miles this is a top pressing with great fidelity (180gm on two LPs) feeding a good SQ MC Cartdridge
the same album, but on CD ripped to disk and playing via:
1 Daphile at 128 DSD playing via XMOS to NoDAC/ 74ACT74 to a pre filter feeding an EDCOR XS1100 transformer (Now this transformer is a better option to my way of thinking because it has a meatier core than a Lundhal or Jensen etc which makes it better for those trying things because the core doesn't saturate at low DC offset currents. It also has benign distortion levels and flat frequency response to 50Khz)
2. an XMOS/AK4490 DAC running balanced into my pre - amplifier (and up until this point in time I was satisfied with this DAC)
Once I have adjusted the output/ volume levels of each of the three sources and cued each to be playing the same track at the same time (more or less) i can instantly switch between any of the three sources and therefore immediately detect differences in "the sound" coming from each of the sources ( my pre amp switches via push buttons connected to relays with no perceivable delays between them)
Now for the verdict:
The NoDAC is a better sounding DAC than the AK4490 because it renders ie converts digital into analogue across the whole spectrum of musical sounds
ie human voice, bass, guitars, brass, drums and percussion (ie transients)
Common garden variety DACS (ie DAC chips and others) do a great job with simple sounds eg sine waves ,where there distn levels at 0dB are to be admired and along with there ultra low noise levels give ear bleeding dynamic ranges, but fail to achieve any where near what the specs would suggest with real music..I will explain in my next post.
Regarding the No DAC and Vinyl well I am glad to say this was a close call with this album - some tracks I preferred the phono sound - others the NoDAC - and I know that is going to be controversial - if I haven't been controversial enough
Now the caveat is that the SNR of the NoDAC is poor and so comes a distant third to the other two sources - Vinyl and CD where the signal level is low ie quiet passages in the music - which is pretty rare in contemporary music.
This puts the AK4490 (or other chip dacs) first
and the NoDAC last
So the upshot of all that is I listen to the NoDAC 90% of the time, Use a DAC DAC where the signal levels are low ( esp if I am using HeadPhones) and I will spin up a Vinyl or two if I am feeling nostalgic ie go completely analogue.

Yes Mark I agree!
Do this work?
"No-Dac" and "No-USB" - DACs & Digital Source / Transport - StereoNET
Have any here tryd to use this?
Or do You have to use the powered ”no DAC”?
