I’ve got a DS Jr. And I was wondering if it many any sense - if there were any benefit - of upsampling in Roon before it gets to the DAC.
Since both the DS and the DSJ upsample everything they get in firmware, it would seem redundant. Or possibly degrading the sound, as I’ve heard it’s always better to upsample in hardware (DS) vs. software (Roon).
The only reason to do it is if you feel the computer filters and/or modulator can do a better job than the DAC. Most cases with very specialized FPGA implementations the DAC should do an amerable job as it’s the main selling point.
Naa… I’m so sick of A:B testing stuff. For me it takes the fun out of the hobby. I like listening.
So if I hear about something that sounds like it’ll make things sound better (and I can afford it, and it passes the spousal filter), I just do it. But that’s just me. And I do make exceptions for important stuff.
For this I’m happy to go with informed recommendations. And I think I’ve gotten that. Thanks.
I have the DS Jr. and I have gone back and forth with software DSP upsampling and just straight native to the source 44, 48, 96, 176, 192… and to my ears and setup, native sounds best by a mile/km, and as a side effect, the load on the computer is almost nothing, and that’s a good thing. In other words, I no longer upsample on the PS DS Jr.
On my second system, I do upsample by X2 and sometimes up to DSD256, but that’s on a exaSound E22, different ball game, entirely.
I’m asking for other peoples knowledge and experience. You’re implying that not deciding based on my own listening is a bad - or “uneducated” - decision. So be it. That’s my prerogative. I prefer getting other people’s insight and experience to A:B testing.
I read somewhere on this forum that one of the benefits of up-sampling upstream of the DAC is to allow the DAC to do less work internally (generating less noise internally?) and perhaps the computer software uses better algorithms.
And if you can up-sample to the DAC’s max supported rate, then the DAC essentially turns into a non oversampling DAC. Eg, I hear a massive improvement when I let Roon up-sample to 32/384 with my HiFiberry Dac+ Pro.
My DS up-samples to 20x the DSD rate now though (with Huron) which Roon can’t do, plus the inputs are limited to double DSD anyway, so I turn Roon DSP off with my DS since the DS will be upsampling regardless of what is done before.
All personal preference though but unless I’m able to upsample to the Dac’s max rate (like I can with the Dac+ Pro) I like to turn upsampling off.
Upsampling before the PS DS (jr or sr) really doesn’t make much sense - at least in my mind. You paid PS Audio for their DAC algorithm which is suppose to do that very function as cleanly and efficiently as possible. If you didn’t believe in their product’s ability to do what is a significant marketing point of their DACs then why buy it in the first place? You could have saved considerable money by buying a DAC on a chip that relies on higher sample sources for input.
I’m a DS jr owner. I believe in letting PS Audio do what I’ve paid them a lot of money to do.
Yes good point. If you want to leverage the best software up-sampling can offer, best to buy a DAC designed specifically to utilize software based up-sampling. Otherwise you end up passing the audio through 2 modulators as well as a plethora of other detrimental processes not necessary if the DAC was designed from the ground up to utilize software based SRC/SDM.
