Popular Post StreamFidelity Posted March 27, 2020 Popular Post Share Posted March 27, 2020 HQPLayer is really not easy to understand. For example, if you think you have to set the volume control to 0dB, because you have a preamplifier, you've already lost. It's recommend -3dB or -4dB for sufficient headroom. I now use the HQPlayer without preamplifier and control the volume with the HQPlayer. Operation is via Roon. Great sound! I prefer PCM > DSD. The DAC is to be operated in NOS (Non OverSampling). I have listed some filter and modulator settings here. Blue are my favorits. biosailor, Solstice380 and motberg 2 1 Grigg Audio Solutions Owner StreamFidelitys Setup: Sonus Faber Amati Futura | T+A M10 | T+A SDV 3100 HV | fis Audio PC & Server | GigaWatt PC4-EVO+ | JCAT OPTIMO S ATX | FARAD Super10 & Super3 | Keces P8 | Afterdark Buffalo Switch | fis Audio Cables | Solidsteel HJ-3 / HY-A Link to comment

Or is the function of the dithering filter? Thanks 🙂 The number of bits depends on the DAC. My Denafrips Terminator can do 24bits / 44.1, 48, 88.2, 96, 176.4, 192KHz on all input and 1.536kHz on USB & I²S input. It doesn't matter for DSD, DSD is always 1 bit. Here is a list with DACs bypass digital filtering: Which DACs bypass digital filtering?

No, as far as I know, the HQPlayer does not change the music signal. In digital streams, the aim is to generate an analog amplitude from 0 and 1. In my opinion, the DAC (Digital Analog Converter) can do this better if it doesn't have to perform any filters and no upsampling (NOS). That is why it is not the output format (PCM or DSD) that matters. Important is only the format that is available shortly before the conversion. To my ears, DSD is more organic and less digital. Some manufacturers automatically convert all signals to DSD, for example PS Audio DirectStream DAC and EMM Labs DA2. These DACs are not for me because I prefer to do the DSD conversion with a powerful Audio PC and HQPlayer.

A good friend visited me and brought two DACs: - Matrix Audio DAC X-SABRE Pro - Gustard A20H DAC Purpose of the visit: I wanted to prove to him that the source (Audio PC) is more important than the DAC. The DAC should of course be able to convert without errors. According to the Forum Audiosciencereview, both the Matrix DAC and the Gustard DAC (an other model DAC-X26) have excellent measured values. We first heard with the Denafrips Terminator: high resolution, precise, excellent space and still no digital sharpening. Very analog sound with a lot of body and bass foundation. Then we heard the Gustard DAC: musty, imprecise, no space. We connected the Matrix DAC. Better but a bit annoying in the high range, digital sharpening. Our results: - Good measurements do not mean good sound (but in my opinion, good measurements are an important basic). - The weakest link determines the sound. - Music can be heard very well with the Gustard DAC and the Matrix DAC. But compared to the Denafrips Terminator, they were disappointing. There is always an improvement on DACs possible. 😁 motberg and digitaldufferme 2 Grigg Audio Solutions Owner StreamFidelitys Setup: Sonus Faber Amati Futura | T+A M10 | T+A SDV 3100 HV | fis Audio PC & Server | GigaWatt PC4-EVO+ | JCAT OPTIMO S ATX | FARAD Super10 & Super3 | Keces P8 | Afterdark Buffalo Switch | fis Audio Cables | Solidsteel HJ-3 / HY-A Link to comment

Yes, I use HQPlayer with great enthusiasm. What do you mean by changing the music signal? Changing the frequency response is a change for me. For example, by folding for room correction. Or through the loudness switch or bass control, etc. In my opinion, the great filters, oversampling algorithms, dither and DSD modulators from HQPlayer pursue a single goal: to get as close as possible to the original analog music signal on a digital level. Is this a change in the original music signal? I'm not sure. 😉 Grigg Audio Solutions Owner StreamFidelitys Setup: Sonus Faber Amati Futura | T+A M10 | T+A SDV 3100 HV | fis Audio PC & Server | GigaWatt PC4-EVO+ | JCAT OPTIMO S ATX | FARAD Super10 & Super3 | Keces P8 | Afterdark Buffalo Switch | fis Audio Cables | Solidsteel HJ-3 / HY-A Link to comment
