Hi, I’m using dedicated roon server + HQP win10 machine, and it is not very powerful. Generally I’m using Roon for library management and Tidal and HQP for DSD128 upsampling with ext2 filter without stuttering.
Yesterday I tried to upsample data in Roon and sent upsampled DSD256 audio to HQP and it worked! Additionally, I can use poly-sinc-xtr filter in HQP if I upsample data on Roon. Also I can see the all flow on Roon’s signal path diagram.
So, I want to understand that is this flow reasonable?
In this scenerio:
- Which filter is in use, filter on roon (ex. precise 7th order ) or filter on HQP (poly-sinc-xtr)
- Or is data filtering twice? Firstly on Roon then on Hqplayer?
- What is the difference of upsampling method and its quality between Roon and HQP?
- Which part is more important on sound quality; modulator or filter?
