Just asking. @luisma31, what is a front end upsampler and HQPlayer? The streamer or transport?

Hqplayer is an app that runs on a PC, can be under windows or Linux in headless mode. It is not a streamer you can say it transports the audio but conceptually I see it differently.
When you send audio to a dac the Dac uses internal upsampling and digital to digital and digital to analog reconstruction filters for the entire digital to analog conversion. Obviously the Dac executes this conversion with simple mathematical operations and IIR and/or FIR filters.
If instead of sending audio to the Dac you send it to a computer first to be pre processed by a high speed Intel or AMD processor with more complex filters and operations doing the heavy lifting of conversion and passing near perfect digital audio afterwards to the Dac for final conversion the results in my opinion and others are outstanding.
So it does digital to digital conversion passing the result in DSD or PCM format to the Dac.
I don’t like this analogy but If you are familiar with Chord it does kind of the function of the Mscaler.
I have friends that conceptually never even tried it because they say it add colorations, I have other friends that will never go back to a system without using it.
This is another bad analogy but kind of valid, a cheap dac is simple an expensive dac will have more parts and components and software developed by the Dac designer to make the digital to digital conversion more accurate and sophisticated, typically the expensive dac sounds more refined, lowered noise floor and such this is what hqplayer does
I hope this helps
Edit, hqplayer has an internal basic player for local content which is very basic. It is also integrated in Roon so you can stream from roon to hqplayer directly qobuz or tidal or roon's library local content too. The pc holding hqplayer you connect via USB to the Dac or you send the audio via the network to a renderer pc, raspberry or what have you connected to the Dac
In the mid 2000’s, I auditioned the Musical Fidelity Trivista 21 DAC. That was an audible wow. I kept that DAC for 15 years.
Traded it in for a Lumin D2 so I could play hi Rez streamed audio, and I kept it for two years. Demoed a Lumin T2 and within minutes it was “wow”. Shortest demo I’ve ever done, the T2 was so clearly superior to my D2 with LPS.
I still prefer vinyl but on hi Rez songs, the difference is closer.
