HQplayer 4 and Mac-mini M1

[Schafheide]

Maybe the female receptacle inside that problem hole in the plastic connector is damaged now?

[Schafheide]

That is the greatest news! I cannot wait now to get mine!!!

[Schafheide]

re "The MMM1 is so far upstream, and so I was skeptical at first."

I don't look at it that way - purely from an amplification point of view, I figure that the closer to the source, the better it has to be (because the faults will be amplified) - ie spend a lot of money on the turntable and the cartridge.

What say you?

[Schafheide]

BTW - shouldn't all of this be in the TeraDak MMM1 kit thread?

Just asking 😪

[Schafheide]

1. Until today I used these settings on my MMM1

poly-sinc-gauss-xla
poly sing gauss-long
LNS15
ASDM7ECv2

this produced DSD256 (48k 256)
CPU temps approx 60C

2. My recently discovered settings are -

As above except -

AMSDM7EC 512+fs

This produces DSD512 (48k 512) - no dropouts
CPU temps approx 30C

 

Comments please.

[Schafheide]

As you wish.

Well,,,,,,,,,,I can answer my own question.

ASDM7ECv2 @ DSD256 is the definite winner!

[Schafheide]

@MikePid

Thank you.  We all should help one another.  Hopefully, once mine has cleared the enormous Covid-related hold-ups at the various way-stations, I too will be as happy as you!

[Schafheide]

Re (How many veils are there anyway??? 🤣)

I think that, unfortunately for our wallets, there are an infinite number of veils.

[Schafheide]

I have zero probs with 24/192 to DSD256 using ECv2 & hires-lp.

Beware of the latest MacOS update for your M1 - 1 April 2022.

Surely not April fool from Apple??

Either way, once installed, my M1 could not recognise my normal boot process for HQP.

My other M1 (not upgraded) is fine - thankfully!!!

[Schafheide]

Thanks. Obviously I need to look elsewhere.

Solved - the update had somehow changed the Sharing setup!

[Schafheide]

Happy with 4.18.0 on my MM1.  Especially the new FIR2 SDM Integrator (more space around the orchestra.

Is it just me, but, since the upgrade, I have to turn the volume up a couple of notches?

[Schafheide]

Thanks to some Miska Magic, my Mac Mini M1 has now broken the "sound barrier"!!

DSD64 (& DSD128 &DSD256) to DSD512 (without noisy i9 fans).

My settings are -

HQP 4.18.1, buffer Default, 48k DSD, AMSDM7 512+fs, grey Multicore DSP, FIR2, wide.

 

But I cannot get AMSDM7EC 512+fs to work without dropouts.

 

Also PCM96 (and up to 352.8 PCM) to DSD512

gauss-hires.

 

And PCM44.1 to DSD512

gauss xla

 

The SQ improvement over DSD256 is fantastic!

 

Thank you Miska.

[Schafheide]

I have just updated to 4.19.2

Based on your info re this update -

Bug fixes and component updates. Core usage improvements in certain cases.

It would seem that our Mac Mini M1 are not included?  I was hoping to be able to use EC.

I do appreciate that you cannot always perform miracles!

[Schafheide]

These settings worked for me as well. But recently I switched to AMSDM7 512+fs for DSD512.

For DSD source I use FIR2 / wide.

Wow, interesting!  I'm still on the TeraDak 200W LPS.  Someday I might try a better LPS, but very happy with the MMM1 LPS upgrade with that.  My setup has an EtherREGEN and ultraRendu (both powered by really nice LPSs with nice fuses 🤑).

Hello again!

In case you have not already done so, I recommend that you update ultraRendu NAA to 4.2.0 - improvements in sound stage and "power".  But, in any case, it is free!

[Schafheide]

My amp volume control is very close to max.  I run M1 - ethernet - NAS - ethernet - ultraRendu - SingXer SU-6 - Holo May KTE - Mjolnir Carbon CC.  As I see it, the only possibility is to somehow increase the volume from the M1 ?  Ideas?

[Schafheide]

For playback of PCM files to 352.8/384, I used to use Shaper/Dither LNS15. Since swapping to Shaper/Dither NS5, I notice that the 4 Mac Mini M1 Performance Cores show no activity!

Which Shaper should I be using?

[Schafheide]

I only just noticed.  (I normally playback to DSD512.  I am just trying PCM playback.)

The cores only get used for DSD playback - make sense?

[Schafheide]

My reason to try PCM was due to you alerting me to the 6dB loss when playing DSD.

Playing DSD, with HQP set to -6dBM and EQ requiring -6.4dB, my poor amp volume control was (for some classical files) was at the max!

So now, playing PCM, it is several clicks back!

For me (without EQ enabled) my May KTE @ DSD512 is fab.

Unfortunately my DDC is limited to 384/DSD512.

[Schafheide]

Yes, this is checked. But doesn't this only apply for DSD to PCM conversion?  I seem to remember Miska stating this?

[Schafheide]

The amp is balanced, using XLR cables from the May.

[Schafheide]

Out of curiosity, does anyone know the typical output signal level of an Intel PC vs that of our Mac Mini M1 ??
