  1. The Roon Knowledge Base has specific step by step instructions for moving a Roon Core and all library data to a new machine. It's not hard, just follow the steps they outline and it will work fine. Important to look there so you don't screw it up. The NUC would be great for Roon Core or Roon Rock. If you are really going to just use it for Roon, load Rock (make sure your NUC is one of the supported models first), as it will give you the fastest, most seamless experience. The setup you outlined above should be great.
  2. SQ-no. Those programs are about convenience, UI, DSP, mulitroom, etc. Of course, all sorts of DSP functions that are built in can help improve SQ. But just in terms of straight playback-no.
  3. Hearing and listening aren't the same thing. I have typical diminshed hearing for an over 60, but can "hear" things that younger people can't - because they haven't trained their brains to listen properly. There is anecdotal evidence that loss of high frequency hearing actually makes one more sensitive to the sounds of bright systems - they sound harsh. No one knows exactly why; one of the ideas is that the loss of ability to hear the high frequency harmonics makes the high frequencies one can hear sound harsher. One of the advantages of modern digital audio is that we
  4. One of the Topping DACs is a good choice, you have lots of models for $500 and much less. Features that match your system and listening habits are important here. You might also want to take a look at the new Schiit Modius, it's gotten good reviews and measurements for only $200 US. Has balanced and unbalanced output, and an AKM chip.
  5. I built something with the same motherboard and an i7-10700K CPU. Basically the same speed as what he built. But instead of fanless or water cooled, I went with a gaming case with soundproofing on the case panels and large, slow spinning CPU and case fans. It's basically dead quiet - below the ambient noise threshold in my home - and stays cool even when doing heavy duty work. The quiet fans and the case aren't outrageous, so you can build something that will function just as well as what Chris built for much less. Doesn't look as cool, though.....
  6. He's not talking about straight playback, he's talking about using a Linux streamer and heavy duty up-sampling using HQ Player. It does take a powerful PC to fully exploit the capabilities of HQP. For some of the HQP settings you even need to add a CUDA capable video card and offload some of the processing to the video card.
  7. I'm a big proponent of the RPi 4. I think many audiophiles won't hear any difference between a Pi4 as an endpoint and many much more expensive endpoints. It's biggest issue is that it doesn't fit the audiophile paradigm of " it has to be expensive and esoteric to be good" and also ongoing audiophilia nervosa. It's peanuts to try, and if you don't like it you can re-purpose it for some other task in your home. Maybe you WILL like it, and you will save yourself hundreds or thousands of dollars. Pay a few dollars for a nice aluminum case, and it even looks like a hi-fi component. BTW,

  9. Yes, I do it, and I also sometimes convert all music on the fly for playback as DSD. I find that PCM presents more "space" between the instruments; DSD presents the playblack as if the instruments are more "connected" or what I call a more "solid" presentation - less "space". DSD playback also sounds a bit more "relaxed" . I mostly listen in PCM, but sometimes switch to DSD mode. I agree about the Kii ASRC - it seems to do such a good job that the "DSD" attributes are preserved even when converting internally to PCM. I also have an external DAC connected to the Kiis, and som
  10. Once you place the order, the VPN doesn't matter. You can download it without the VPN.

  12. Hans is probably one of the worst sources available for this. He has no clue. There is no "third unfold", as he claims somewhere. There is first unfold and then second unfold. The second unfold is actually just upsampling with filtering by the MQA fllters. Hans is just parroting MQA marketing speak without understanding what he's talking about.
  13. You can do the "first unfold" of MQA in software like Audirvana . IMO, that's most of the benefit-if you hear one. I wouldn't buy a DAC on the basis of whether is does the second unfold or not. I'd buy one based on sound, features, and price. Then if it also does the "second unfold" - that's a bonus. The second unfold is either upsampling and use of an MQA filter, or just the use of the MQA filter built into the DAC. The first unfold in your software gets the file up to 88 or 96k. If the original file was at a higher sample rate, it is then upsampled in the MQA DAC to
  14. It could be DC offset on the line. Sounds to me like it is. I had an issue with that once. there's a thread here: https://www.stereo.net.au/forums/topic/239149-buzzing-toroidal-transformer/ Here's one perspective on it: https://www.pooraudiophile.com/2015/03/how-to-fix-dc-offset-and-transformer.html The symptom of that IS the amp transformer humming. And yes, a specific device in the house like a heater, lamp, printer, fridge, etc. Can cause it. There are relatively inexpensive DC blockers on the market This one works: https://avahifi.com/pro
  15. I produced the standard audiolense correction filters at 44.1, 48, 88.2, 96, 176.4 and 192. Roon chooses the correct filter for the sample rate and the suitable number of taps are applied. Nunber of taps changes according to what you are playing back.
