  1. Note that the I2S input Spring 3 is not HDMI. It uses same connector and cable, but that's the only common thing. Do not connect HDMI devices to it!

    Not really, when there are effects it is usually load-independent. Yes, that's one of the purposes of NAA.

    I'd say it's less, since you need only one cover image for each album, instead of (likely) repeating the same cover in every track file... But as detached it of course takes same space as it does embedded into a single track's metadata.

    Yes, if you didn't yet have any of the supported detached cover files available. Embedded cover art is used for per-track covers. But for album covers, detached ones are needed. Reading cover images from embedded metadata for album purposes is too slow and inefficient.

    If it overheats and slows down too much, you will start having audio drop-outs, and you will surely notice. Until then it won't affect sound quality etc.
  6. Let's say you output at DSD from HQPlayer. This means you have well over 160 dB dynamic range in RedBook frequency range. This leaves you volume adjustment range of at least 64 dB without any loss in resolution. It also means that the digital noise floor is always some 40+ dB below your achievable analog noise floor. Let's say you use my recommended settings of 20-bit output and suitable noise-shaper with PCM output instead. This gives also about 160 dB dynamic range in RedBook frequency range. The internal DSP pipeline in HQPlayer has SNR of over 300 dB and dynamic ran

    Usually there shouldn't need to consider CPU core temps. For example I'm extremely rarely looking at my CPU core temps. Operating systems and BIOS have thermal management and in addition CPUs have built-in thermal protections. Usually reason to look at CPU temps is in case one has performance problems due to thermal throttling. Thermal throttling is way to limit CPU speed in order to protect the CPU, but it should only happen in case of inadequate cooling. For example Apple M1 silicon is performance limited through thermal throttling on MacBook Air and iPad where there's no cooling fan, unlike
  8. To me, to PCM side sounds flat on transients (a bit "flap-flap"). It lacks the body, weight, depth and kick of DSD side running at DSD256 with ASDM7EC (88.2k Daft Punk). Also on dense mixes the PCM side can become congested (24-bit Opeth - Pale Communion, 96k Steven Wilson/Porcupine Tree/Storm Corrosion). This is common to any R2R I've heard so far. But at 1.5M PCM this effect is the least. Just remember to adjust for the 6 dB volume difference between the two when comparing. P.S.Now it is getting closer to time of my favorite fall time song - Opeth's Eternal Rains Will
  9. No, (assuming you also change to PCM output) if you perform any DSP, like volume control, convolution, or anything else, you must set some proper dither. Otherwise you have a distortion generator. And well, doing NOS that way you have a distortion generator anyway since imaging distortion will be in tens of % range. But without proper dither you have two distortion types instead of just one. (not counting IMD and TIM resulting from excessive imaging since these depend more on your amplifier gear) Filter choice is up to your personal preferences. I tend to use shorter filt

    "Load optimized defaults" in BIOS, set XMP Profile 1. And then leave Linux kernel as default. It will at least screw up HQPlayer... HQPlayer manages it's own settings based on the hardware it is running on, and any OS interference will degrade performance.
  11. You can just ignore that stuff, it is related to onboard audio and HDMI audio links.
  12. NAA OS image is similar, without bridge, instead has Name match for "e*". Which also means that it will sit waiting for all found interfaces to come up before networkaudiod gets started. So for your cases, nothing would ever get started with it. This is the main OS configuration difference between NAA OS and HQPlayer OS. Since HQPlayer OS binds to the bridge, it is happy already when DHCP succeeds on any of the interfaces (through the bridge), also allowing multi-homed configuration that doesn't fail... But it will add to CPU load and packet processing time.
  13. No... I have a cheap passive cooled Nvidia GPU for such purposes.
  14. You can remove the bridge config file, and just make DHCP bind to a specific port, and if you want, turn other ports off as you have done.

    MQA never contains anything more than 2x the base rate, thus at most 88.2 / 96 kHz worth. 352.8 kHz MQA has been converted to 88.2k and then folded into 44.1k container throwing away enough many bits to make the ultrasonic content fit in the LSBs. When it is decoded, it is unfolded back to 88.2k and then if DAC supports it, upsampled with one of MQA's 16 (poor) upsampling filters back to 352.8k. MQA is never lossless, after the unfold it has less loss than in folded base rate form.
