  1. Anyone here have any experience putting a USB Isolator of the JCAT/Intona variety in front of their QB-9 Twenty? I've been happily running a USB cable from my Roon core machine (formerly a sonicTranporter, now a Roon Nucleus) directly to the QB-9/20, but see a used JCAT for sale from a private party for a reasonable price and feel like experimenting. I've heard that there are a few DACs that don't play nice (or even play at all) with these devices, some Hegel DACs for example. Any insight or informed speculation re JCAT/QB-9 compatibility would be appreciated. jonathan
  2. I'm a satisfied QB-9 Twenty owner going on 3 years now, but looking for thoughts/suggestions/advice re an issue that's just developed. I set up a brand new Roon Nucleus Rev B for the first time the other day, migrating from a sonicTransporter i5 that I’d been using for the last few years. Installation and setup went well and all is running smoothly, except for the Nucleus's apparent inability to recognize the DAC's DSD capabilities. Roon is not presenting the Native DSD option for me in setup, only 'DoP' or 'Convert to PCM'. When paired with the sonicTransporter, Roon recognized the QB-9/20's DSD capability and offered a selection for ‘native DSD’ in the setup. That's gone away now that I’ve migrated to the Nucleus. No other changes to the system or setup were made. Any QB-9/20 users here who also connect to a Nucleus? I so, what's been your experience? I've put up a similar post and query on the appropriate Roon Community support forum and have had a couple of non-official responses, but so far no solutions. Perhaps someone here may be able to provide insight. Also...paging @Jake Forsyth :-)

  4. I am surprised to hear that a ‘distributor’ did the conversion for you. I’m under the impression that the upgrade was only performed at the Ayre company itself in Colorado. If you did send it directly to Ayre, I’d be more than surprised to hear that they’d done sub-par work. Thats not their M.O. How is your digital filter setting? If it’s in the ‘Measure’ mode, you may want to switch to ‘Listen’ mode to see if that gets you get closer to the sound signature you seek. (Or, if you’re already set to ‘Listen’ then try ‘Measure’ just for the heck of it).
  5. At his time, I am keeping the HDPlex LPS available to potential buyers of the Mac Mini only. Should the Mini be sold without the power supply, the HDPlex will then be posted for sale. Thx for your interest.

  7. The short answer, no. Not to these 67 yr old ears anyway, and with the very small DSD catalog that I own. YMMV however. But suffice to say, both methods do sound outstanding to me 🙂
  8. Ah, makes sense now. My QB-9 tops out at 384kHz PCM. Thus the 128DSD limit via DoP..
  9. Excellent! If I’m not mistaken, DSD128 is the max in Roon when using DoP. Will go higher if your streamer/DAC supports Native DSD. I’m getting DSD256 in Native mode with my QB-9 Twenty and sonicTransporter i5 (running latest software update).
  10. Yes, regardless of whether you’re set up for DoP or Native DSD, the display on the QB-9 Twenty should show ‘64’ in the situation you describe. Not ‘352’. Double check your Device Settings in Roon (and also the DSP settings) to make sure everything is in order. The number you are seeing seems to indicate that your DSD files are being converted to PCM 352 for playback. I have no experience or familiarity with the Pro-ject Streambox, so can’t speculate whether the problem could lie in that part of the chain.
  11. It appears that it is an issue of mislabeled format. The album is actually a 5.1 multi-channel version, not stereo as the Qobuz app has labeled it. (Notice that the album title even indicates 5.1). Try this one instead and you’re likely to have better luck. BTW, I streamed the version in question via Roon, and Roon confirmed it to be 5.1 channel format. Should probably flag @dmackta on this.
  12. Yes, exactly. My wife occasionally uses the account at work via Qobuz app on her phone. She only listens to what's already there and is not interested in saving or 'favoriting' anything else. However... I have now come to a new realization about the content of my 'Favorite Artists'. Upon further examination, I think that the list is a reflection of all artists associated with every album I have in my library. And I see that my initial reaction/observation (that a significant number of artists were unfamiliar to me) can be explained by the following: Back when ECM first made the majority of their catalog available to streaming services, in a fit of over-exuberance I proceeded to save every single one of their titles into my Roon library (although I was using Tidal at the time, not Qobuz). That was somewhere around 1000 albums if I remember correctly. And, no, I didn't save them one at a time. I found a method to select all ECM and do a bulk-save. 🙂 It appears that the unfamiliar artists are associated with the (many) ECM albums in my library that I have yet to explore for a listen. So...no totally bizarre, random artists in there. It just seems that somehow all of the artists in my entire musical library became Qobuz favorites. But that still leaves the mystery, how and why? 'Favoriting' artists is just not something I've ever really done and therefore haven't been inclined to even look in the Favorite Artists section much (if ever, prior to now) so it's possible that this overpopulation has been there since the beginning. 1) The theory that there is/was some anomaly in the interaction between Roon and Qobuz is definitely worth considering. 2) I transferred my Tidal library to Qobuz using Soundiiz when Qobuz became available in the U.S. and I made the switch. I wonder if something happened there that caused Qobuz to think that every artist from all of my albums were 'favorites'. I'll embark on the process of deleting the unwanted favorites via the Qobuz website as dmackta suggested and I'll see what happens from there. Thx @PAR @rando @dmackta for your input.
  13. Thank you David. Greatly appreciate your time and help here. This will definitely speed up the deletion process. My only wish would be that there could be a 'select all' checkbox at the top 😊. Nonetheless, scrolling down the list and checking off artists for deletion will be much preferable to the alternative within the app itself.
  14. Well, thank you very much for correcting my typo (putting the '+' in the wrong place). Yes indeed, my sub is 'Qobuz Hi-Fi Sublime +' Now, back to the actual issue I'm trying to understand/rectify... First, let me clarify that I am indeed talking about behavior in the Qobuz app itself, not Roon specifically (although the over population of 'favorite' artists can be observed in Roon's Qobuz section as well... Qobuz -> My Qobuz -> Favorite Artists). Actually, there is. In Qobuz app (either desktop or mobile) go to an artist's page and click on the 'heart'. That artist is now 'favorited' and will appear in the Artists section of Favorites. To remove the artist from Favorites, go back to the artist's page and 'un-heart'. My Release Favorites are all correct, I did select each and every one of those. Same with Tracks Favorites (only 18 or 20 there and I selected them). It's the Artists Favorites that's behaving differently and I'm trying to understand why. If I ever favorited any artists in Qobuz I could probably count the number on one hand, yet there are well over 1000 artists in that list. I'd like to whittle than down to a handful but I'd really rather not go to each artist page one at a time to 'un-heart' them. So to reiterate, hoping someone can offer insight re: why the Artist Favorites behaves this way. Bug or anomaly in the US Beta app? Some other reason? And also hoping to hear that there may be a trick to enable a bulk 'un-heart', 'unfavorite' (or whatever you want to call it) the majority of that list. Thanks
  15. A Favorites 'issue' in Qobuz App I'm using a U.S. Hi-Fi+ Sublime subscription, primarily accessed via Roon at home but sometimes via Qobuz app when traveling. Hoping for some help understanding and resolving a curious situation/problem: 1) Favoriting artists is not a feature I've used much, if at all, yet just today notice that I have well over 1000 artists in the Favorites/Artists section of the app. Many of them I've never even heard of. I definitely did not individually 'heart' all of these folks so am wondering if there is any known current issue or anomaly that could explain this curiosity and what I may do to prevent further unwanted additions. 2) I can see no way to delete them en mass. Anyone have a method to do that? I believe they total 1300+ and selecting each individually to 'un-heart' them is a rather unsavory prospect. TIA
