DAC Upgrade
I currently using a Bryston BDA-1 DAC and although it is a pretty good DAC, I want to upgrade to a 2r2 DAC. I recently purchased a Jays Audio cdt2 mk.ll transport and it is exceptional. My budget is in the $2,000 range and after careful review, I have narrowed the list to Schitts-Yagdrasil, Denafrips-Pontus and Holo Spring 2 level 2(new). Unfortunately, It is difficult to compare the three of them side by side, so I have to rely on expert reviews. I am looking for a DAC that is transparent, extended but smooth highs, 3D midrange and tight bass. My equipment is Prima Luna Prologue Pre Amp, Prima Luna Dialogue HP Amp and Silverline Sonata Mk.III speakers. Any thoughts?

@georgehifi I couldn’t use the link as it says too many page visits. Either way, it doesn’t change the fact that NOS mode has no benefit in regards to transparency over OS mode, all it does is reduce the treble, add IMD, and introduces aliasing. It just shows you can’t trust your ears when you know what you are listening to. |

Either way, it doesn’t change the fact that NOS mode has no benefit in regards to transparency over OS mode, all it does is reduce the trebleWell, you’ll just have to stick to that belief, and be deprived. In NOS mode with the Holo Spring dac playing PCM RedBook, there is more body to the sound, and the treble has more transparent and noticeable harmonic extension to it. As for DSD it doesn’t interest me, maybe it sounds better in OS mode on the Holo, who cares. |
@georgehifi In NOS mode with the Holo Spring dac playing PCM RedBook, there is more body to the sound, and the treble has more transparent and noticeable harmonic extension to it. Making claims in regards to frequencies you can’t hear are we? https://www.stereophile.com/content/holoaudio-spring-kitsuné-tuned-edition-level-3-da-processor-meas... It very clearly has reduced treble in NOS mode with 44.1kHz, and with 96 or 192 it is practically identical to OS mode. Is “harmonic extension” the new marketing description for harmonic distortion. If so, that directly contradicts your statement about transparency, as we can clearly see it has more distortion in NOS mode. It’s like arguing a bookshelf speaker has deeper bass than a 12” sub, it just isn’t true. You should really consider the possibility what you are hearing is non-existent, which is common in Hi-Fi (power cords, headphone break-in, silver sounding different than copper (when conductivity is matched), etc.). |
+1 @mzkmxcv NOS will often roll off more than designs that upsample. R-2R is inherently less linear overall and has differential non-linearities also as it is impossible to design precision resistors to the requisite degree of accuracy. Therefore you will get more correlated musically related distortion. This is a fact. This is why engineers prefer Delta Sigma for linearity. Ultimate linearity is DSD or high resolution PCM through a delta sigma style DAC. The only issue with lower bit rates is higher noise. This is why the latest delta sigma designs are 6 bit - a hybrid between R-2R and a single bit delta-sigma which is achieved by massively parallel 1 bit delta sigma converters (equivalent to a resistor network that achieves bit depth through additionnof various resistors) |
