I’m starting a new thread as not to continue to derail the AirLens thread.

I’m very interested in knowing what your HQP settings are. I don’t have a DS DAC but from the reviews I don’t think I’ve ever read it described as bright. 🙂

Anyone else using HQP with the DSD? What are your settings? What are you hearing that’s different / better?

thanks

Any suggestions would be greatly appreciated.

I can’t seem to get DSD to work right, so I just skip HQPlayer when I play DSD.

Thank you

I would try shorter/less process intensive filters. For SDM defaults: poly-sinc-ext2, for DSD source settings: PCM conversion poly-ext2, SDM conversion wide; PCM Noise Filter Standard. DAC bits should also be 24, the DAC is going to throw away the last 8 anyways.

Thanks to ipeverywhere for starting this topic. I think it’s a good idea. 🙂  
I’ve been using HQPlayer Desktop with my DSDAC (MK I) for about 3 years. Although, I must confess that I don’t take full advantage of HQP’s comprehensive filter capabilities since I’m only just beginning to understand ‘filters’ and, besides, I’m content to just leave the filtering regime to Ted Smith’s programming.

Originally, I was a BridgeII user but got the itch to change when I started reading opinions that the I²S input(s) to the DSDAC sounded better than using the BridgeII as the input. In addition, DSD256 was just coming onto the scene, at least as far as the DSDAC was concerned. So I started looking around for ways to ‘stream’ my locally stored PCM and DSD library files into the DSDAC. With my (in hindsight maybe too limited) research into ‘transporting’ DSD, I ended up with HQP feeding a Matrix Audio X-SPDIF 2 DDC device.

Probably more information than you learned readers need to know but, at any rate, here are snips of my HQP settings. What I’m trying to achieve with these settings is to just use HQP in ‘pass-through’ mode. That is, to have it act as a conduit to just read the DSD (or PCM) files from my NAS server via Windows folder sharing, using the ASIO driver, send the bitstream onto the X-SPDIF 2 via USB and then onto the DSDAC via I²S. Happy to accept any suggestions to better achieve my intent.

Is there a software update for NAA / HQPlayer support in the future?

Hi Jdee, welcome to the forum. Do you mean HQP support in the PSA DS MK2 DAC itself? The DAC has no streaming capability itself at all. So that is a no. If you mean in the PSA AirLens streamer that matches with the DAC, then that is also a no as Conversdigital, the maker of the streaming card in the AirLens, reacted with disinterest to all contacts I know of so far, including from the owner of HQPlayer. There are plenty of options though. IFI devices tend to support HQP NAA with USB output to the DAC. The Holo Audio Red does too, including many output formats. The Red can also run the HQP OS. If you are conversant with Linux, then the Fitlet 3 is a good choice as well. There are also Small Green Computer and Sonore devices that support HQP. Though others would need to advise.

Thank you very much for your feedback! Hopefully also LUMIN is supporting NAA soon, do you know if they are working on that?

I do not know. Only found this post from last year that was not promising: “HQPlayer with Lumin X1? → Not currently supported, Peter Lie, LUMIN Firmware Lead”. Lumin does their own upscaling, but not with all the filter choice of HQP, is otherwise all I know.

Yes times are changing. No matter how good or powerful a processor in the LUMIN is, to have the freedom and choice to use a far more powerful computer with all upsampling and filtering options is something that is a gamechanger.  
I hear LUMIN is in general passionate about their software development. So I am sure they are changing their mind and also incorporating recent market developments into their software planning, and NAA is one of that.  
But it would definitely help to get a recent feedback from LUMIN, guess they are following these conversations anyway?

I expect it is unlikely they would be monitoring for mention of them on another manufacturer’s sponsored forum. More likely that they would follow Lumin threads on non-branded audiophile forums like Head-Fi.
