Which HQP Filter are you using? [2015-2023]

[Moy]

Hi!
Much appreciated your feedback, I’m a newbie fan of HQP, I tried the suggested options from @IgorSki :

1. You may step down to 44.1kx64
2. You may step down the modulator to something light like DSD5, your current choice of modulator is optimised for x512 rates and above.
3. You may step down the filter complexity to smth we call “-2s” filters, like “poly-sinc-short-mp-2s”
4. you may want choose 44.1 source rates to start

And I was able to play the Tidle MQA files, when I choose a High Res FLAC, the app crashed

Anyway, I’m quite happy with my PCM config for the moment, nevertheless, I’m looking forward to an M1 mini to upgrade to DSD128!!!

I’m looking forward to an M1 mini to upgrade to DSD128

M1 Mac mini is capable for ASDM7ECv2 → DSD256 or AMSDM7 → DSD1024.

[Moy]

Excellent! Please share configuration

Well I finally have joined your “cool” gang😄 I’ve got a new Mac mini with Desktop running, with a RPi as NAA.

Sounds mint. First time listening to DSD.

[Chunhao_Lee]

My M1 Mac mini is 8GB RAM / 256GB SSD version. Suggest 16GB RAM. Since macOS’ USB connection is DoP DSD only and will cut DSD rate to the half so suggest to acquire a single board computer as NAA to gain full DSD rate (or buy an iFi Zen Stream as no-brainer solution).

[Moy]

Wow ! Thanks for insight, if I get iFi zen streamer then I can keep using my old Mac Mini ? How it works?

[dabassgoesboomboom]

Great stuff.

What’s the DAC @steven_goodier ?

[Moy]

I’m using DAC-60 on a Accuphase E-260

WHen you click on Networback Backend “Device” dropdown menu, what other options to do see?

I expected to see “naa” there instead of “hqplayer”.

That’s using the NAA image for RPi4?

[steven_goodier]

Yeah I used a new image Jussi built yesterday.

[steven_goodier]

So should I have the IP address for the NAA (RPi with image)?

I think I’ve used the Mac Mini IP, in Roon for set up/zones.

Also if I want to use the image on different Pi’s in different rooms, I’ll need to use their IP to set up zones in Roon?

[Moy]

This is the ONE @Chunhao_Lee ?

Looking forward for DSDimension @IgorSki finally!

Hi guys, do these settings seem correct for iFi Zen? I’ve tried many combinations, this one is the only one I get SDM working, but my CPU is at 274% and dropping out with all sharper filters except DSD5. It was a great upgrade to have now bit rate 44.1x128. Many thanks in advance.

Mac Mini M1 16GB/256GB. Using SDM exclusively for Holo Spring 2 DAC. It was a bit tricky to set it up to run headless via Screen Sharing

Good HQPlayer configuration for Holo Spring 2 KTE?

Going back to try this cracked the nut, thanks so much! I had tried to do exactly that but Preferences wouldn’t let me. I just remembered to option-click the disabled choice and it told me that the Mac had Filevault on that prevents auto-login, which it’s the default at setup time. When I turned Filevault off I was able to change the to automatic login, and all is working now How many people are still arguing in the forums about this when the answer is so simple, although really hidden…

Current HQPlayer settings:

So after many tests, finally found the way for HQP + iFi Streamer on a Mac Mini 2012.

1. After updating and firmware on ifi zen, KEEP System selector “1” All in One.
   

   

2. On ifi on setting play back option, change volume setting to “Hardware” (fixed)
   

   

3. It will be automatically able to be mounted as a device on roon (you can test it but once added in HQPlayer it won’t be able to work unless you quit HQplayer app)

The HQP settings
4. In the “All in one setting” ifi streamer will also have NAA activated, so just add on
Backend
NAA
Device
The DAC on USB of ifi streamer

Input Device Settings
Backend
[none] ← very important like this

Then is done!

My CPU is at 300% but ok. I have the TG Pro app to keep fans working fast to keep CPU cool.

Notice: I tried using ifi Streamer in NAA (4) settings and it was not working, no audio coming out. Only PCM worked, but very low volume.

[Chunhao_Lee]

Suggest SDM Pack change to None (red square) and DAC bits change to Default (green square). DSD rate can change to 44.1x256.

Same as iFi ZS, change to native.

[IgorSki]

Careful @Moy - it is addictive!!! Hahaha!

I can see your choice of filter and modulator in the last post. “ext2” filter with ASDM7 - this is quite good combination. and “ext2” is a go to filter for many.

Also many are impressed by “EC” modulators and “ECv2” in particular. These however require CPU power.

I wonder if you can make 5EC modulator on your hardware? If you try, pick “-2s” filters for starters.

[Moy]

Many thanks!
I’ll check later tonight!

[Moy]

Yeah!
I’m lucky yesterday I sold my node and got for almost same money the ifi streamer the same day!

And slept at 2:00 am finally fixing it!
