  1. What you posted, in the way you posted it, was classic passive-aggressive.
  2. Just following up something I mentioned previously about jitter and distortion, I had a look to see if I could find any numbers on this. In the Linn press release it says “extremely low levels of distortion thanks to a new ultra-low jitter oscillator and carefully designed clock distribution network”, so no figures, but seems to confirm Linn are pushing the jitter level lower they could previously In the 5 minute Organik DAC video on YouTube. Linn are claiming a clock accuracy of femto seconds, one millionth of one billionth of a second and claim it to be the most accurate, lowest jitter
  3. My biggest issue with Roon since upgrading to version 1.8 is the unnecessary clutter I now seem to have to wade through. For example, if I select an Artist (directly, or via search or from an embedded link, etc), following the artist’s bio., the first thing I get is “Popular”. I don’t want to see what’s popular (I don’t care) I want a list of albums so I can pick one. Trouble is, on my iPad, there’s not enough space to get to Albums with scrolling through the stuff I don’t want to see.
  4. Yes. Ground (or Earth) planes are used as “references” for other voltage levels in a circuit, but when there are perturbations in the ground plane it’s value as a fixed or static reference becomes less effective.
  5. I’ll try and attempt some kind of explanation. Let’s take a simplified, non-oversampling DAC presented with 16bit/44.1kHz digital audio data. When the DAC chip converts this into audio, each sample (44,100 samples a second) needs to be converted at precisely the right time relative to the sample converted before and the sample to be converted next (samples spaced precisely 22.67 micro-seconds apart). In order to obtain this precision, a crystal oscillator is used to “clock” the conversion process. But even Crystal oscillators are not perfectly locked to a fixed frequency, they have small
  6. I’m fairly certain that the inclusion of an optical Ethernet connection on the new KDSM’s has nothing to do with the bandwidth limitation of copper Ethernet. A 1Gbs copper Ethernet connection is already massively more than is needed.
  7. Thanks for jumping in. It will be interesting to see what Linn have to say about why the addition of a fibre Ethernet connection. I guess it could just be there in case the customer doesn’t have a copper Ethernet socket nearby, just a fibre one, but given how ubiquitous RJ45 connection to Ethernet is, it does sound like the very edge of a niche.
  8. Hi Billz, I take it that’s taken from the ASR web-site. I’m not sure that’s an entirely fair conclusion. John Swenson has decades of experience as an integrated chip designer, specifically related to network architecture. ASR are a very objective oriented bunch and tend to value measurements more than listening. I notice the New Generation Klimax DSM’s now include an optical Ethernet port. What’s your view as to why they’ve done that ... offers no benefit, just pandering to audiophools or genuinely offering an improvement over some issue encountered with copper Ethernet (we can specu
  9. ^^^ That’s a five page article above, but when I paste a link, it seems to have pasted in the first page (only) rather than the link (bloody forum trying to be clever). Let me try again Uptone EtherREGEN white paper
  10. As a starting point for some technical opinion, take a look at this Uptone Audio “White Paper” (/article) regarding their EtherRegen switch (commercial influence, obviously, so not necessarily a purely scientific endeavour) If you spot any technical mistakes or things you don’t agree with, let us know and take it up with upTone and see what they say. If not convinced either way, listen and decide
  11. Yes, that’s what I’m thinking could be the case, albeit without Linn’s tacit acknowledgement.
  12. Moomintrol, I know, I read that, but *if* there are no downsides, and you cannot figure out why Linn have priced the two units the same, then surely best and most prudent advise would have been to say “If you need AV probably best to grab the AV one. If you only play music and have absolutely no interest in AV then grab the AV one anyway”. I notice on the Loud & Clear website, probably on other retailers websites as well as it looks like Linn provided copy, that “the addition of HDMI does not impact audio quality in anyway”.
