  1. Tim at Holo/Kitsune is pretty sure that this would require a kernel update. Currently the only way is Windows/ASIO.

All rights reserved. Here it is. This is while playing 44.1 material from Tidal/Roon ( running on a Win 10/64 machine) up-sampled to 1.4112 PCM using HQPlayer (also running on the same Win 10/64 machine. There is music playing but it is garbled and distorted. Just to be clear, I cannot even try DSD 1024 and don't care about that. My machine will do DSD 256 just fine and DSD 512 if pushed but I actually prefer the sound of PCM to any DSD rate that I can do. When I play PCM 7xxx all works fine and sounds great. Thanks for looking at this but don't spend too much time on it as all I wanted to do was an experiment to see if PCM 1.5xx filtering was any better than PCM 7xx filtering. This is not anything critical. I do suspect that others may have similar questions about The ability to use these rates going forward.
  3. Jesus, Just tried it and distorted sound is all I can get. It does show the correct 1.5xxx as the incoming signal on the Spring 2. HQP and Roon are also showing the correct numbers so I would guess that the uRendu software or hardware is the problem. I thought I remembered that the Rendus topped out at 7xxx/512. I think I saw something about it in a post by Barrows recently. It is not a big deal as 7xxx PCM sounds great but I had just wanted to see if 1.5xxx PCM was any better.
  4. Do you need to give Minneapolis Power Company advanced notice when you are going turn it all on?
  5. Jesus, Is it possible to get an update to enable PCM 1.5xxx/DSD 1024 output from my uRendu? My Holo Spring 2 supports this and the HQPlayer NAA supports it. I would like to try the PCM 1.5 xxx option now and maybe the DSD 1024 option later if I ever build a server that could do it. The PCM 1.5xxx processing is within the ability of my current hardware. I am not sure if this is a software limitation of sonicOrbiter or a hardware limitation of the Rendu series. Thanks, Bob
  6. Another way to look at this is that optimizing whatever is practical in the upstream chain can possibly obviate the need to spend more on a higher end DAC. It may be possible to get the sound of a much more expensive DAC with some judicious upstream enhancements. It may also be that no matter how good the DAC, it will never be a great DAC without an enhanced front end. I would love to see this explored at some point. Put a great DAC behind a good front end and then put a good DAC behind a great front end and compare. It would be interesting.
  7. Thanks for another well written, very informative and useful review. I just recently purchased a Holo Spring 2 KTE DAC so I am no longer actively looking but I enjoy reading your reviews. Using HQPlayer and the Spring, I can get part of the way to the performance level of these DACs at a price I could afford. I may look at one of these later when I re-do my entire system. Thanks again

    HQ Player

    Jussi, Do you expect that these new modulators will run on the Windows version of HQP? Have you been testing them on a Win10/64 system yet? From what I have been reading above, it looks questionable. I hope they do as I would love to try them.
  9. Great choice and at least they don't cost as much as a house ( a down payment maybe ). What color did you go for (piano black for me)? If I ever decide to replace my B&W 802s, these would be on my short list. I sure hope that they work well for you in your new listening/working space with all the treatments now in place. Looking forward to your second article. Congrats!!
  10. Please don't misunderstand me. As I said, this will appeal to some users especially those who don't wish to pay for software. I used LMS for so many years and although it worked, I was really happy when Roon came along. I don't mind paying them for a very good and getting better product. I can stream Tidal and Qobuz, have great metadata, seamless integration with HQPlayer and I can do it with ease using Sonre and SGC products. I no longer have a local library so MPD/YMPD are not something I would use. Thanks for the continued innovation.
  11. This may appeal to some but I don't think Roon with its robust functionality need be concerned. Also, this is totally against the whole reason for the Rendu series of products. The Rendus were supposed to be an endpoint quiet zone with all the storage, retrieval and associated processing happening elsewhere. This puts it all back in one place. There is still the problem of back-up and additions/deletions. The material for the SD card will have to be archived somewhere else and new material will have to be obtained on a real computer and then moved to the SD card. I tried this for streaming only with both of my Rendus a long time back (it has always been possible to run both Squeezelite and LMS together on a Rendu) and it worked fine but I thought that it sounded better with LMS running on another machine (a sonicTransporter) elsewhere on the network. In the end, no matter how you dress it up, it is still LMS. For those asking if this will work with Roon, I doubt it. Roon core does not run on the Rendus, only Roon Ready which is strictly a rendering function.

    HQ Player

    Jussi, A couple of feature suggestions: -automatic application of MQA filter when MQA material is detected (similar to what you have now for hi-res) -conflict notice something like "This won't work with that" Just a few ideas. Thanks for listening, Bob
  13. Mine has worked great for years with no issues. I suggest that as a trouble shooting experiment that you pull out the high-end USB cables and insert some standard certified USB cables and try again. There have been reports over the years where some of the high-end USB cables cause these types of problems in some equipment combinations. If that does the trick then at least you will know where the problem is. If not, ask Alex for replacement unit. Also, email him and he may be able to diagnose the problem. There are several other potential problems here that he may be able to help you with.
