    Guys can someone outline an easy but audiophile way to run a HQP rig for 2 channel system in a living room setting?

    If you are asking for a non techie way of accomplishing this with "off the shelf" devices and without needing to access a computer I hardly doubt you will find any. I personally have helped others to experience HQPlayer sending them small PC's running the software, some users have decided the sound is so good that they can't turn back to their former systems (including known speakers manufacturers). I have done this at no cost just because I'm friendly, I don't sell PC's, I don't sell HQPlayer and I'm not associated with the industry at all but I provide no cost advice, you can take it or leave it.

    I know this is OT here, just trying to answer @TA75 question.

    I actually now have two separate locations, 15 km apart, both with >100 Mbps fiber internet, now I need to set up VPN to be able to access also between the locations.

     

    Hi Jussi:

     

    You have probably seen this but just in case.

    https://www.wireguard.com/

    • Much faster than IPSEC and OpenVPN
    • Included within the Linux kernel
    • Runs in any device, even Raspberry Pi's
    • Seems like a good case for your VPN if you don't have it working already :)

    Take care

    I know what the digital only, no preamp sounds like.

    You do know I agree for your system, but the sound quality with or without preamp depends of course on the DAC to be used, not all DACs analog outputs are the same just like not all amplifier inputs are the same, the "gain" will of course depend on source (DAC in this case), amp, and other parameters like output/input sensitivity (voltage), impedance and such, here you have quite a few combinations. But I understand in your system the sound could be best (to your ears and maybe mine too) with a preamp

    Now, the Lumin X1 supports LeadH volume control. Supposedly better than regular digital volume

    Digital volume designed with the correct filters, depth resolution and such will provide excellent noise floor which typically most analog controls can't do

    If it make things sound better, then use one.

    I can't disagree with you on this one

    DACs will output about 2 V unbalanced and about 4 V balanced

    Typically unless some DACs designed with "non typical outputs" May which was 3V and 6V IIRC, the Okto with adjustable custom output and such.

    Then you are not reaching maximum output level from DAC and you can deal with this in digital domain..

    And that's the beauty of all this with digital

    That depends on the DAC and the necessity for additional gain depends on the gain structure of the power amp as well as the sensitivity of the loudspeakers.

    You said it shorter than I would, perfect

    How can I optimize my PC to get the most powerful upsampling out of it?  What is the bottleneck?

    It is not clear to me from your post but IME, and I'm running everything in Ubuntu not Windows, the biggest difference in upsampling was moving Roon away from HQPe and leaving HQPe alone with nothing else running, when you start getting in the EC modulators and high CPU usage in general Roon although it doesn't use much, maybe 3 to 5 percent of overall CPU, these "interruptions" into hqplayer processing and more importantly core distribution / coordination processes will impact as much subjectively speaking as 30 to 50 percent.

     

    I'm running a passive Ryzen 5600X with HQPe and moved Roon to an ESXi VM with only 2 virtual cores (the physical is a 3700X) and my system performs flawlessly.

     

    You don't have to virtualize of course, you can get a small nuc or industrial small PC or else and run roon there, that's what I will do if I don't want the virtual anymore. I backup the roon vm twice a day with Veeam Community edition free so no worries if I need to restore and no need to go through roons highly inefficient backup.
    By the way roon talks to HQPe over wireless and it is perfect, no drops or anything.

     

    You can try it with a laptop or small PC as a POC.

     

    Ideally IMO I would use Ubuntu or HPOS not windows but everyone has their preferences.

     

  5. Very nice review Chris, I especially like you decided to introduce the HQPlayer "variable" in it, this is something most reviewers leave out, which I understand to be more pragmatic about results but "reality" is many of us use HQPlayer and we wonder about its benefits and interaction with certain DACs, thank you for including it and for the detailed settings and comments. My experience with the terminator mimic yours in terms of preference for upsampling.

     

    Great review

    As some of you know, I am a longtime HQplayer user

    We know, since the 1st alpha or beta release IIRC

    Any opinions or ideas are welcome. 

    Can only speak of my own experience.

     

    1. Started with a NUC 4 years ago, connected to my DAC (the DAC model for this comments is irrelevant), core i7 NUC, good results, noisy because of the fan onboard. Powered the NUC with Uptone's JS2

    2. Added an NAA, cheap PC older generation Intel, fanless celeron, industrial type passive PC. Powered by the JS2, boost in quality.

    3. Built a new server, passive HDPlex chassis with Ryzen 5600X, I can do 7EC with no problems on the passive and I'm happy with it, that said I won't do passive again. Connected DAC directly to the server USB 3.2 port, nice improvement over older hardware (mainly I think because of 7EC). Server powered by DCATX HDPlex adapter with a Dell power supply connected.

    4. Added the cheap celeron industrial PC as NAA, low EMI, low processing power, powered by the JS2. Improvement over connecting the DAC directly to the PC, don't know if because EMI or just because NAA with its buffering protocol and such and just handling the DAC is better.

     

    All I can say is I do prefer the NAA over other configs. Waiting on my PH SR7 to try it with the passive server but it might take a while.

     

    The NAA can be purchased with no memory for $80, memory you could get Apacer if you are into that from Ebay for $25 - $32 8Gb and you can do ramroot too, in the BIOS you could configure every single parameter like disabling unused USB ports, Serial connections, onboard network or onboard adapters, Intel Sleep states and such.

     

    IME the NAA is so far preferred.

     

    Good luck Ted

    You don't need a driver with Linux do you?

    Yes you do, it is the ALSA driver which is integrated with the kernel API, but this driver it is "usually" pretty standard, I have seen it fail on such environments (original Allo USB bridge is one of them which stopped working with the Terminator DAC after Oct 2019 update)

    May's Thesycon's ASIO driver does not like any other ASIO driver to be active

    Thank you, so under Linux the May will work with none of the issues of the Thesycon's, maybe others though

    With my issues with the Holo asio driver and DSD through HQP

    Hi @Quadman

    Just wanted to ask, so the May + HQP has interfacing issues due to drivers? is this something related to Windows, or Linux, or both? will the May accept 48k resampling from HQPe?

    What do you suggest the speed and voltage be changed to?

    Feel free to experiment but I would leave in automatic (in my systems I have it like that) I discovered after testing memory on different systems (for other applications not necessarily audio) that if you want a stable system it is better go with the defaults. Even underclocking and undervolting memory under its max specs (which you would think would not create any issues) it actually does and makes the memory to start generating errors (I've spent weeks running memtest pro for different types and settings). Of course an audio system doesn't have to be strictly stable as audio is really not a critical app so give it a spin if you feel like it.

    Not linear PSUs though, but the 240W Streacom ZeroFlex

    With the Zeroflex rated at 240W you don't have to worry about the boost @Miska, I'm running a Dell 240W myself and the CPU and overall system is fine. @StreamFidelity is using the LPS which are "anemic" in the amount of power to be delivered compared to an SMPS (I know about the SQ opinions and such and I don't take sides on that, everyone is free to do their own choices), 2x P8's, are these the single our dual outputs? @StreamFidelity, the 5V seems it is only dual output.

    You can get that with Undervolting

    True, I might just add "if the CPU supports it in a stable fashion" the 11th Gen being a hybrid not only (based on the current reviews) runs hotter but has increased IPC and the voltage dynamics could be different.

    Do you  have any idea how much draw with 100% cpu util?

    Based on his snapshots around 53W? max value

     

     

  13. Additionally and I don't know if this is your case but I have found issues myself with other VPN's which required using "specific ipsec supported routes" to be added for the VPN. Since you are using NordVPN (which I never have)

     

    Look for this option and turn it off if present "Invisibility on the LAN"

    turn off this option as well "cybersec" if it is in your client

    I should be check in the PC or network?

    Check the routes as @Miska suggested on your SERVER PC not the NAA, since you are running Linux Mint (which I'm not directly familiar with but I'm familiar with the others)

     

    If you are using netplan (modern linux does) for the network config be sure on the adapter (network adapter that is) connected to the NAA you have this entry on your netplan (in my case eno1 is my network adapter)

     

      eno1:
       dhcp4: no
       addresses: [youripaddresshere]
       routes:
       - to: 224.0.0.0/4
         scope: link

     

    netplan apply (after)

    there you are adding a static route for multicast, still the VPN might change the routes and add its own entry for multicast I don't really know what the case is

     

    If you are not using netplan for the network config just enter this on a terminal to test (the command on Mint might be slightly different)

     

    route add -net 224.0.0.0 netmask 240.0.0.0 dev eno1
