  1. I will definitely try NAS, with both ethernet and Wifi, just never could see how it could be better than standalone. An active LAN /WiFi interface seems like it would be more or less as harmful as active storage device , and then you end up with more stuff to worry about on sending end of the network. It would be very foolish to dismiss without trying it though, especially when so many seem to like it.
  2. I didn't realise the 2GB version is so inexpensive, it was only priced more than the 4GB on amazon (probably have excess 4GBs to shift) . It is a no brainer for sure (ordered one on Ali Express) The dedicated USB3 chip is one of the big improvements on previous Pi s, very nice to see it has its own 25MHz crystal rather than being clocked by PLL from main clock in the SoC. Should be better for SQ by default but also opens up the possibility of feeding an external clock (can be hit or miss if this works well/at all since most chips arent designed to accept an external clock via the crysta
  3. Hi, hope you don't mind answering few questions about this (as I trust your judgement) which pi version was it you had and was it powered by the standard SMPS? what software (wtfplay etc.)?
  4. A few different reasons. while I think a powerful PC has particular benefits for SQ it also clearly/inevitably has flaws. I don't like how wasteful is to have all that computing power and only use a fraction of it 90% of the time (I dont use oversampling/conversion of any kind), PC components lose value so rapidly it's better to sell sooner rather than later. It will be interesting to try something different with the Pi... but that depends if people have anything positive to say about, Will probably just pick up another MoBo if not. One thing that spurred this on though was a recent d
  5. After bricking a MoBo im considering selling the remaining PC parts and getting a Pi 4 instead. Compared to previous Pi it seems to be a big step up in quality while still keeping the simplicity. Anyone have any feedback on it for audio, specifically for standalone use?
  6. Would it be possible for you to take a photo of the inside of the fractal DAC?

    try normal poly-sinc
  8. PCIe based memory has a more ''direct'' path, but is less flexible and ideal when it comes to power as explained, SATA allows use of external/modified power supplies more easily. ime NVMe just sounds plain worse regardless of power or the direct path. PCIe Optane is the ultimate storage option but is expensive and limited to smaller capacities
  9. On a side note, I think there might be a bug with PCM Closed Form 1M or could be a trial limitation? Sometimes there will be some silence at the start of the converted file... conversion is 44.1k 16bit to 88.2k 18bit.
  10. ah that was a pretty stupid question when you can just output to flac and convert to wav with something else.
  11. Is there any way to disable metadata on wav output? For some reason my SD player is refusing to play wavs with the latest version of trial (wont get into but its an issue with the SD player, not HQP, the new files play fine in any normal software), I have some wavs converted from long time ago on an older version of trial and these still work, I notice the new version has some metadata left on the wavs while these old files dont.

    Has there been any measurement thats show the difference between no dithering and basic dither when upsampling? Ive found comparisons of dither and noise shaping. also comparisons of upsampled 24 bit data truncated to 16 bit vs dithered to 16 bit... that is still different to upsampling 16bit 44.1khz to 24bit without dither and sending it to a 24bit non-oversampling DAC, right? no truncation in that case?
  13. HQP Pro is very expensive, what are the best alternatives?
  14. what do you mean by this in relation to what he said? Is looking at a single factor in a vacuum any different to a number? I believe dithering would impact another factor, SNR, for some reason I dont understand SNR or THD doesnt seem to directly relate to the linearity ''bits'' measurable on output but it would impact the dynamic range of the music. If we are going to put a factor into a vacuum is linearity the right one? I have seen delta sigma DACs measured on asr that fall a few bits below 16 bit linearity and yet they were not deemed ''bad'', I dont* know enough abo
  15. Have you found that with other R2R DACs? Holo spring uses a different technique to achieve good linearity, some kind of digital compensation, most DACs like Soekris seem to use some other method, based on PCM1704 DACs.
