I have a very resolving system with a very large sound stage.
On its own it up samples any incoming PCM signal to a PWM (Native format of DSD) at 844Khz.
Most beautiful trailing sounds I’ve heard from my system.ĭynamic but prefer the poly-sinc-mp family.Īs I mentioned earlier I have a NAD M51 dac, PCM only no DSD decoding. Poly-sinc-shrt-mp is my go to for anything driven by drums/percussion.Įdit: These filters really shine with decay. Rock and Roll baby ! Dynamic and detailed. These all sound good, but I keep gravitating back to poly-sinc-ext. Poly-sinc, poly-sinc-shrt, poly-sinc-hb, poly-sinc-ext Spacious but I prefer the linear phase poly family below which seems more detailed. I understand the WTA Filter used in the Chord DAC is a closed form interpolator. These are non-apodising filters (meaning noise from the ADC process is left where it was). I couldn’t distinguish fast (lower CPU) from the original. Very intensive on the CPU, starts the fan on my BRIX. I suspect it’s because of the extra processing it requires and it might not appear with more powerful hardware. Huge tracts of land !Įdit: Compared to poly-sinc-shrt-mp I hear some increased harshness in high frequencies with closed form. I thought these had the biggest space/soundstage. So far I have tried the filters described below (all upsampling Redbook local and Tidal to DSD128 into an Auralic Vega using ASDM7). These CA threads also contain useful information and discussion about the filters: Geoffrey Armstrong’s KIckstart guide contains some basic information about setting up HQP. The latest version of the manual, including descriptions of later filters, can be found in the HQP folder.

There is a link to the Version 3.1 manual in the Signal Chain footer in Roon. The filters are described in the HQP Manual. Thread to discuss which filters and modulators we are using in HQP and why.
