Why you want upsampling and upconversion in a server and why it sounds way better!
tom6897 Ditto from me too, up/over/sideways sampling all BS, just another way to sell more dacs to the gullible.. Should just have a good listen to Redbook 16/44 PCM converted through a "good" discrete R2R Multibit nos dac Cheers George |
So I just tried upsampling to DSD 128. It takes up about 5-10x more CPU in the Roon server, I think this is as high as I can go with my pokey A10 CPU. My DAC (Mytek Brooklyn) has issues switching sample rates. Sometimes it glitches, which is annoying when going from my personal library to MQA/Tidal to internet radio. It doesn't happen every time, but it is annoying, so sample rate converting to a common standard removes this issue. I'll see if it sounds any better to me. :) Best, E |
I've done most of my upsampling to 768k using PCM. I have just been experimenting with DSD 512 upsampling on my Lumin X1. Pretty much the same results. DSD always tends to sound a little smoother anyway, but in a way I find artificial. The upsampled sound produced a slight background glare that I did not care for, and certainly did not sound better than playing it at native PCM resolution. |
OK, having just done some informal comparisons I am now absolutely ready to render the definitive verdict on the subject. For me. :) I went from straight PCM streaming to DSD 128. I agree with @rossb - Mostly what I heard was in the range of cymbals. Little that I heard was all that in terms of information, it felt like the top 2 octaves were turned up, and far too much at the cymbal range. It did not seem natural, but I can see why in a quick listen it may be impressive. I did not hear better sound stage for instance, or deeper fuller bass. What I heard was in the range of selecting different filter settings in a DAC. In the end, I’m not keeping this setting active. If I want the same effect I'll turn the treble up. |
