Using HQPlayer (Desktop vs EMBEDED)

Hi!

I have a Roon Nucleus One.
My DAC is a SMSL DO400 connected to my windows pc via USB.

I can play Roon lossless (purple light) with DO400 exclusive mode (RAAT).

I am considering giving a try to HQPlayer given all the positive feedback I’m seeing.

My understanding is that I could simply install the desktop player and add it to Roon as a endpoint.

My question is:

  • since I’m already lossless would I get any benefit of using HQplayer?
  • Since my DAC support DPD512 should I force up sampling to DSD or is better to stick to PCM?
  • I saw some people mentioning NAA. With my current setup having DAC connected via USB is not needed right?
  • I am very new to this , thanks for the pointers!

Usually

A lot of us prefer the DSD.

Not needed.

HQPlayer is one of those things worth trying. I’d download desktop onto your machine there and get started. Play with the modulator and filter combinations. You may find one that answers all your questions. Note, DSD512 is fairly CPU intensive. It’s OK to run DSD128 or DSD256 to give yourself a solid taste for what it can do.

Others may have specific suggestions based on your DAC which I’m not familiar with.

Since it is based on ES9039, if you have enough processing power, I would recommend to try running it at DSD512, with the default filters in HQPlayer for starters at least, and you could try ASDM5EC-ul modulator. If this works, you could also try -light and -super (and x512 fs) versions of those modulators. This takes quite a bit of processing power, so depends on how powerful your PC is, and whether it has an Nvidia GPU for offloading some of the processing. If DSD512 doesn’t work, I would try with DSD256.

Once this works, you can also switch to ASDM7EC version of the same modulator (like ASDM7EC-ul) for example and compare. Once you know which modulator you prefer, you can look into the oversampling filters. In the PDF manual, there’s a filter table and some rough suggestions (by no means definitive) which ones may be good fit for your source material.

Please also remember not to turn HQPlayer volume higher than -3 dB, this leaves (usually) enough headroom for inter-sample overs that commonly happen with modern source material. Otherwise there is risk of triggering the limiter, which is best avoided. If limiter is triggered, Limited-counter increments and the volume knob turns red.

It worked seemlessly!

With CUDA offload CPU is at 13% and GPU 50%, which is great. (ASDM7ED-super 512+fs).

@jussi_laako would you say poly-sinc-gauss-hires-lp is a good filter for all genre (mainly POP but looking for something versatile)?

Yes, those default filters are the best general purpose filters I could come up with, thus the defaults. Those work very well in a balanced way for wide variety of source content.

I prefer poly-since-ext3 myself as a good all arounder, usually with ASD7ECv3.
