What connection between the LinQ and the La Scala was your friend using?

I believe he was using a custom AES cable from Aqua, the dealer advised it was worth approx $1k cad.

I was not paying attention as he already had it set up

[dericchan1]

This is the rest of his set up

 

KR842VHD based Monoblocks, DECADE ONE HORNS (110Db), PATHOS SYNAPSE PREAMP, MELCO N10EX MUSIC LIBRARY, AQUA LA SCALA DAC

He should really try the I2S connection between the LinQ and the La Scala.

Not sure about that the dealer supplied the custom AES cable for connection for my friend I home trial. Even if the i2s is a touch better than the AES, it still would not worth the 100x price difference with a pi?

Well... I have a Pi4 here running Miska's NAA image and I had a LinQ. I liked it enough to send my Pacific back to Poland to have the ethernet input changed to an I2S input...

That’s good. My friend has since bought a used pi4 and ordered an intona unit. Perhaps he can try a Mercury streamer down the road for i2s connection.

Time to praise HQPlayer and its author. What a piece of SW!!

 

My DAC is a Mytek Manhattan II and I run ASDM7ECv2 with poly-sinc-short-mp upsampling to DSD256 and it just sounds wonderful. I run a separate NAA which made quite some difference.

 

Thank you, @Miska

 

Cheers

Am I the only one who finds issue with 4193. On HQPLayer desktop. Windows 11. After upgrading to 4193, no sound came out when in SDM mode !! Switch back to 4192 and all is well. Did it a few times and same thing happened?

No issues for me but I am still on Windows 10

I almost never have any problems with HQPlayer. Unlike almost every other player I have tried. Did you verify that all your settings were correct before pressing play? Sometimes they can get changed in an upgrade.

@Fredc maybe the question is superfluous .....
did you completely uninstall the previous version before installing the new one? 🙄

I read your post this mourning, very impressive!!, and I agree 1024 is where the magic happens (me with no EC you with EC).  MSI MB"s must have an easy adjustment for ring voltage, the Asus board I have and the one I built for my buddy has no easy Ring voltage adjustment that I could find, and my trials brought no joy.  My next board when I move to a 12900K or 13900K will be MSI.  Your voltages are sure pushing it, I would be leery running over 1.4V all the time.  Nice cooler, I use an artic freezer 280AIO, which also replaced an noctura air cooler and it handles cooling just fine.  Excellent and kudo's to you for getting it to happen with NO GPU

Thank you @Quadman 

 

Let's be frank - we did not know back than. And another huge thing that happened over these last 6 months is Ubuntu 22.04 LTE - with more optimizations for Alder Lake (and more patches seems to come) + (certainly) Jussi's builds for  "Jammy" + BIOS patches, bug fixes etc... Personally, while mingling with 12900K/KS is/was fun and brings rather satisfactory results, I can't wait for 13900K.

 

I really want to close and put my HQP mega-brain tower into the cellar away from listening area and just plunge into the music ! :)

I did. Use Revo uninstall to complete removal, restart machine before installing 1493. Same configuration and volume settings. Done this many many times previous updates first time problem. If it's only me, very strange.

CUDA offload in use? If so, please make sure you have recent Nvidia drivers.

 

Which CPU do you use? Try switching Multicore DSP between greyed and checked.

This was using same settings as music off hard drive. I had occasional dropouts before 19.3 but nothing like it is now,

My ongoing saga of dropouts on 19.3 qobuz: now I get no music but I notice that on task mgr I am getting 99% of network usage even with no upsampling. Remind me again how I can capture the logfile please.

NAA in use? 802.3x active? What kind of internet connection do you have? For me, on my internet connections, freewheel mode downloading next track occupies about 50% of local network for couple of seconds. But since the NAA traffic is prioritized with 802.1p/DiffServ, it is not affected even on the same link. And there's anyway still lot of bandwidth to spare.

These are now roughly equivalent like:

sinc-Ls = Chord Mojo/Hugo

sinc-Lm = Chord Dave

sinc-Ll = Chord MScaler

 

 

are these apodizing? 

 

sinc Ll is 1m taps 

 

sink m is apodizing at constant 1m taps 

Sink mx is apodizing and variable minimum 1m taps

sink l is non apodizing and 2m taps

sinc-L are non-apodizing and a lot like Chord filters in other ways too.

 

sinc-S/M are completely different and apodizing.

 

Mx is 1M taps at 16x multiplier. So 32x multiplier is 2M taps, 64x multiplier 4M taps, and so on. Typically you would run at 256x giving 16M taps.

 

sinc-Ll is 65536 x conversion ratio taps. So for typical 256x this gives you 16M taps. sinc-L is twice that.

There are often such pictures to Hi-Res as for example from Qobuz. It is shown that with Hi-Res the reconstruction of the amplitude is finely graduated than with a CD. Is this representation really correct? As far as I know, the sample rate only represents the audible spectrum. For example, for a CD, half of 44.1kHz = 22.05Khz (Nyquist frequency). I mean this says nothing about the quality of the reconstruction from digital to analog.

Does a higher number of taps mean a better (finer) reconstruction of the amplitude?

 

Is there a display of the used tabs in the HQPlayer or can this be implemented?

That applies only to the non-oversampled and unreconstructed data. You can see such only from output of filterless NOS PCM ladder DAC. After normal oversampling and reconstruction analog filter they would look the same with a smooth analog waveform.

 

What changes with source resolution is available frequency range and dynamic range.

No, it generally means steeper cut-off. Although the transition-band steepness depends on other factors too.

 

Similarly amount of pass-band ripple and stop-band attenuation also depend on particular filter design. Not on number of taps.

 

Better reconstruction depends on the filter design and rate conversion factor of the filter in question.

 

Also remember that more taps -> longer ringing -> worse time domain performance, while frequency domain performance gets better. So the most difficult task is to make both time and frequency domain performance as good as possible at the same time although they have 1/x relationship. This means having just right number of taps, not any more, not any less. With good filter design you can achieve more with less taps.

 

MQA looks only in time domain at the cost of frequency domain. Chord looks only in frequency domain at the cost of time domain.

 

For good transient performance you need both time and frequency domain.

No, I consider it pretty meaningless number.

 

For some filters I just put the figures in the manual because Chord is making so much noise about this aspect.

Figures for the rest are in the manual. It is easy to calculate.

@Miskahi Miska, will an allo usbridge signature  with the raspberry Compute module 3 work with hqplayer as a NAA or the NAA image is only compatible with raspberry pi 4?

 

thanks

No, NAA OS won't work on it. NAA OS and HQPlayer OS are RPi4 only.

 

There are other OS solutions that ship NAA functionality and may work on it though.

 

[dericchan1]

@Miska sorry to trouble you. I actually have a older allo usbridge with the sparky sbc. The preloaded dietpi gui actually shows a NAA daemon option there. Will this actually work as a Hqplayer NAA?

 

 Thanks
