TT -> Phono Stage --> RME ADI2 PRO Analog --> HQPlayer PC (RIAA) -> RME ADI2 -> Pre - Amp - Speakers ?

 

 

You wouldn't need your phono stage in the above, assuming the ADI2 PRO provides enough gain.

Can I control HQPlayer Embedded over Ethernet from a Mac, or do I need to use the phone and Wi-Fi?

Yes, you can. Any web browser on the network will work.

Thanks.

Does Embedded require a different license or can I use my Desktop license?

@semente it’s a different one

With all OS versions the behavior is the same: Version 4.13.0 works, version 4.14.0 does not even start.

 

I know have learned, that a requirement for HQPlayer is AVX2, which is not supported on my audio computer, which is pretty old (i7 3rd generation). I checked it with HWInfo. AVX is supported, AVX2 not.

 

My question: Is AVX2 a new requirement or have I just been lucky that it worked before?

 

Then the problem is that your CPU lacks support for AVX2. Yes, it is a new requirement starting from 4.14.

 

AVX2 was introduced on Haswell architecture, in 2013.

Yes, with both browser (for configuration) and with HQPlayer Client (for playback and quick controls).

ADI-2 Pro is a line level device, so it doesn't have suitable gain. IOW, it doesn't have any gain stage. Another thing is suitable input impedance and capacitance for correct cartridge loading.

Yes, as long as the two ADI-2's are separate devices. At least on Linux, thanks to ADI-2 having unique USB ID's for each unit to support connecting multiple units simultaneously. If you want to perfect this, synchronize clocks between the two devices. Downside of the sync is that you lose one set of digital I/O.

My experience with ASDM7ECv2 is as follows:

 

My M1 Mac Mini stutters with DSD256, ASDM7ECv2, poly-sinc-ext2 or poly-sinc-ext3.

Same issue when I keep the rest constant and move to DSD128 and / or ASDM5ECv2

 

Otherwise, I’ve never had issues playing DSD256, ASDM7EC, poly-sinc-ext2 on my machine.

 

Is it some cognitive bias or does ASDM7ECv2 sound better than ASDM7EC?

 

Also: would like to hear opinions of those who tried the new MacBook Pro with the M1 Max chip.

I had hoped that Mac version of HQP (being Linux based?) would perform better than the Windows version. 

 

I continue to have great success playing everything with the Linux based HQP OS up to and including 24-192 PCM => DSD256 x 48, ASDM7ECv2, poly-sinc-ext3. If anything, the load on the server almost seems lighter than with previous versions of HQP.

 

And yes, I definitely prefer ASDM7ECv2 over ASDM7EC.

It'll have to wait until HQP version 5.

Yes, hoping this will be a breakthrough to full HQP capabilty - & that it migrates on to the macmini.

Hey  @Miska is there supposed to be 20x increase in cpu usage when going from 44.1khz to 768khz with EXT-3 compared to EXT-2?

EXT-2 44.1 to 768khz is 1.3% usage while 44.1 to 768khz EXT-3 is 20% usage.

[Yviena]

@Miska also the plot graph seems to be broken in 4.14 version it's always flat

It should be about 4x difference, but these things don't scale linearly due to cache sizes. Likely for integer ratios the difference is smaller, or if you have really fast RAM (I'd expect DDR5 to make difference in these kind of cases).

Regression for the .txt specs. I'm on it, will be fixed in next release.

I think @Miska has stock in Intel, AMD, and other computer hardware manufacturers 🤣

 

Or, hardware manufacturers call him to beef up the filters so they can sell some new products 🤣

I did spend roughly 4 times more on the new 3200mhz Apacer RAM versus the cheaper 2666mhz Apacer ram just for HQPlayer... So add that to the list too.

 

We'll get Miskas Index listed alongside the S&P500 and the NASDAQ

Yeah it's only when it's  trying to do 44.1 to 48khz rate family that the close to 20x higher load presents itself

Would actually be nice if there would some kind of recommendation or outline for a spec vs common usage.

It's what the "best CPU for HQPlayer" thread is all about, isn't it?

Thanks, but not exactly what I meant. 
this thread seems to be all about the “best” cpu for the most extreme usage of HQP. 
not everyone is going all the way to DSD 512

would be nice to have also full configuration recommendation (cpu, mem, gpu) for a few more common usages. 
I for one am using pcm to 768 poly gauss long. But when trying xla or ext3 the cpu chokes up. Would be nice to know what would be recommended for stepping up to xla or ext3. I believe the new intel i9 is not needed - so the “best” cpu thread is not really helpful for that. 

[ted_b]

Good point.  Maybe GPU add-on.

Miska already suggested some setups in the past, but there are so many HW configurations that he cannot cover everything. It's rather on us to share experiences.

For example I am sure Miska did not test my configuration (see my signature), which is so-so but still able of DSD256 ASDM7ECv2 poly-sinc-ext2 or poly-sinc-gauss-long. It gives pretty nice sound on 3.3Ghz 4 physical core Intel CPU (without CUDA offload and only with light convolution - crossfeed and eventually tilt IIR filter). That's with the -3 version. With -2 version I was able to run poly-sinc-gauss-xl, but only for 44.1k/48k -> DSD128. Nice sound too.

IMO for example something like this mini PC for 540 EUR (more powerful than my notebook) should be enough for DSD256 with ECv2 modulators if you don't plan to use some heavy convolution or play multichannel recordings.
