same PCM source played through the PCM & the SDM paths of the same DACWho expects sacd and pcm mixes to be the same, they won't be identical masters.
here I compared PCM turned SDM 256 feeding DSD module of the DAC and PCM turned PCM 1536 feeding R2R module ; please consider scrolling back to post #76 : some consider that all well engineered DACs sound alike and that I'm presenting pure measurement errors if I can measure differencesAt no point would I expect pcm and pcm fed into sdm to measure the same
I'm not sure that dsd and pcm dacs sound the same is a commonly held belief. If they measured the same, sure.
Thank you for showing differences do not come from some DSP trick that would modify the frequency response. I have no doubt your test is as earnest as mine. It simply is not relevant to show how the same music, made of impulses, excite differently certain frequencies of the room and thus our ears , whether it's PCM or SDM processed. Maybe because your test does not measure transients nor any time domain information.I measured them using Holo Spring just now. I don't see any of the large frequency differences posted by esteemed @Le Concombre . In fact, they are a very excellent match with no likely audible differences.

phase is a measure of transients ? please explain how. why can't you simply reproduce my test and show your results ?DSP trick? What are you talking about? And how could I not measure time domain when I measured both, frequency and phase?

that's a funny one : for I purchased a DAC supposed to perform at best identically as DACs costing a fraction, I live under a bridge. All I can see is that nobody dares showing his spectrum.Best leave this one alone, under his bridge...
I pay for their DSD conversion implementation. So far, from Holo Audio I have Cyan DSD, Spring 1, 2 and 3. And I use it only for playing DSD, because it performs better that way.
I could as well ask, why do you buy Spring or May if you don't want their DSD implementation?
(same way for T+A DACs, I pay for the DSD side, not for the PCM side which stays unused)
How does the Spring 3 compare to Spring 2 / May?
From objective point of view, there's no massive difference. Behavior is slightly different, in terms of distortion harmonic structure and such.
I was curious if being sent the same signal to both DACS, you feel there's a sound difference between them (Spring/May), but I guess you don't want to express your subjective point of view.
