Non-Oversampling (NOS) vs,

I am curious. Is a Non-Oversampling (NOS) DAC sound better than a DAC that upsamples the original signal? Or, in other words, is it better to maintain the “original signal” and not add mathematical calculated extra bits?

I also understand that a DAC’s implementation makes a huge different in the resulting sound quality and so does the analog section. I am just trying to better understand a NOS DAC vs one that upsamples.

@soix2 - DAC is a DHT (direct heated triode) tube DAC with separate power supply RR2R board, V-Caps & Caddock + Shinkoh resistors.

the Denafrips Pontus allows you to change from NOS to OS at the touch of a button.
I do change the setting occasionally but always find myself going back to NOS whether the music is served or streamed.

NOS is the better way to go.From my experience over the years I learnt the best way to achieve the sound I want is to keep things simple,all kind of sound "manipulation" gear maybe genuinely trying to improve the sound but in the end just making thing worst.

Thanks for these comments.  So, it seems, maybe, NOS is the better way to go.  

What NOS based DAC’s should I look at?  Are there any USA made NOS DAC’s?    Thanks.

I just settled on NOS for my Denafrips dac. I did spend few weeks testing the difference between the NOS and OS but at the end, I am enjoying the nos better but again the Denafrips is am R2R dac and I am sure it is a matter of taste in music and sound.
