  1. Yes. That was what I was referring to in my last paragraph. Swinging individual drivers is conceptually very different from hanging a boxed speaker on a bungee. Bungee attempts to tackle vertical vibrations, probably from the floor, while horizontal excitation from the woofers is kept within the box and is complex through the box structure. A single woofer on a swing deals with it's own horizontal excitation with a relationship of total mass to moving mass, while the vertical vibrations are a lower order of magnitude and can by assumed not tackled. The downside: limited to DI
  2. Interesting article. Isolating the woofers from the floor vs designing rigid structure from them to floor is always an interesting debate. If the intent is a rigid structure to the floor, one is probably better off holding the woofer by the magnet or motor rather than from the frame/baffle like most boxes speakers are designed. For a while now I've been venturing into DIY active speakers, lately dipoles, and recently placing an 18" midbass nude on a swing. Meaning no box, no baffle, and sitting on a swing. Beyond the dipole operation, the concept is there is no baffle to vibra
  3. Thanks for the input! This is encouraging. I've continued to research this and I'm looking at getting the ADA8P card to enable measuring and premium DA conversion, and as cheaper option than DA8P + AKD8D. But can't buy Hapi here and was planning to do so in a next trip, but alas, COVID came along and I'm grounded. Hopefully can still get it in 2020!! How do you take Acourate measurements? Thru Hapi with another card, or an external card? My current server will likely not have enough power to do DSD convolving. Will see. But the Hapi will stay with me for a l
  4. thank you. Got to love it when things are easier than expected. Doesn't happen often in audio!
  5. I don't seem to able to explain myself: I cannot get anything that's not UTP around here. I'm not concerned with CAT 6 emissions into analogue gear. I'm concerned with fluorescent tubes and LED strips running along the cable and close to it injecting noise into the cable or otherwise harming the signal or gigabit capability. Hence the alternatives to add external shielding to the cable such as copper tubing or aluminum foil tape wrapped around the cable. If nonsense because noise/RFI/EMI doesn't get into the CAT6 UTP, then that's ok. It's different from what I read online, but maybe I misunder
  6. Thanks guys. Some peculiarities of what I'm asking: I'm not using shielded connectors nor cable. Just plain plastic RJ45 and UTP CAT6 cable. The question is if I should build a shield around the cable for the 40 feet that run along the fluorescent tubes and LED strips (and 4" apart). What do you think?
  7. Many network knowledgeable folks gather around here, so hoping you can point me in the right direction. I'm setting up a home gigabit network using UTP cat 6 cable. The cat 6 run from router to switch is 17 meters long and 12 of those meters run along and 10cm away from either flourescent tubes or LED strips. The runs from switch to clients are shorter and away from tubes/LEDs so these are of no concern (I think). Unfortunately, around here I'm not finding STP or FTP cat 6 unless I buy 1000 feet, which I'm not going to do. So I'm wondering if I should add any shielding to those 12
  8. Thanks for the input. My motherboard is Intel S1200KPR with Xeon E3 1265 lv2, 6 years old. I basically copied AudioPhil's machine from back then. I believe he still uses it and his manual recommends not turning on hyper-threading. I run a linear PSU, and have an etherRegen on the way. Suggests I should lower voltage then? AudioPhil, are you running with lower voltage and /or speed?
  9. Hello. This thread would generally be posted in the servers forum, but I'm posting here as hopefully it's a more targeted audience: I remember extensive discussions some years ago in the JPlay forum, and I was wondering if there would be benefits to be had if applied to my Roon Bridge PC running WS2019 with AO 3.00 with Audiophileshell (AudioPC in the signature below). People in JPlay used to report improvements when lowering the CPU and RAM speed, and the voltage, in the JPlay AudioPC. Not sure if this is outdated now or applicable for my case? Thank you! Horacio
  10. Glad you figured it out. It took me a while too. BTW, what is HAF? I use Acourate.
  11. Interesting. I wasn't aware of that suggestion. A while back I had some audiophile slo-blow fuse running in my tube amp without issues. Eventually upgraded the KT88 tubes, which blew the fuse. I put back the stock fuse and worked well. Replaced the audiophile fuse and it blew again. That was enough to let go. Using a larger value fuse would have been an option, although also allowing for less protection to the circuit downstream. It's a non-issue while there is no failure, of course.
  12. Thanks for the follow up. I went on to explore the update log for AO 3.00 and realized WS2012R2 was rather outdated, and went ahead and installed WS2019. So won't be solving for the above anymore. I am likely to show up in another thread asking for other help, though ☺️ Hope you are safe and doing well.
  13. FWIW, I tried running AO on GUI mode and RoonBridge/Roon works perfectly. It's something to do with minimal server mode. What's most puzzling is it was working on minimal-server before I did the Windows reinstall, so there has to be something in the setup. Oh well.
  14. Seems AudioPhil isn't available. Might someone else have thoughts on why this might not be working? Thank you!
  15. Thanks for chiming in. I don't yet have the Ravenna card, but I'm considering the Merging Hapi for multichannel and been looking for eR+Hapi users, and I have only found one who, despite doing on 2 channel, said the 100Mbps port didn't work. From your comment I'm guessing that even a Dante card doing 8 channels at 192kHz would have trouble. let alone if doing DSD, which is something I consider down the road with Hapi. cheers!
  16. How do I check that? I'm assuming tI should urn into minimal server mode and check if Windows Audio Service is working, right? Because it does work while in GUI since Roon Bridge plays music. Regards, Horacio
  17. Hello! Yes, I did run AO again and also said yes to KS after I switched into minimal server mode. The three times I tried this. I don't have another player installed in that PC. Should I install something? Or can I play sounds from an existing app? Regards, Horacio
  18. Hello. Need help figuring out what I'm doing wrong. I had this running until yesterday and after WS2012R2 reinstallation I'm having trouble. System: Roon Server machine is a Win 10 PC, streaming over ethernet to the AudioPC that has WS2012R2 + Roon Bridge + AO 2.20 and connects directly to a USB DAC. I had it running with WS2012R2 in minimal server mode, but after reinstallation it's not working anymore. Currently: With WS2012R2 running with a GUI, Roon Server sees RoonBridge OK and plays without problem. When I turn WS to minimal server mode, Roon Server d
  19. Thanks for the tip!!! I have since gotten in touch with a Hapi user who also uses an etherRegen and indeed he's connecting both Hapi and streaming computer to the A-side of the eR (gigabit) but can't use the B-side (megabit). The recommended setup is streaming computer into A-side and DAC into B-side, so not ideal. That user nevertheless reported sound quality improvement using the eR on A-side only vs using a standard gigabit switch. He's feeding DSD into Hapi, but believe he's only doing 2 channels as he's not going active. Thought I'd circle back with my findings. Th
  20. My understanding (through my questions to users) is one needs to establish a "Ravenna network" and Ravenna as a protocol is very demanding of the network and the B-side can't cope with that. This why ferenc is connecting both the streaming PC and Hapi on the A-side. So can't cross the moat. Would be very interested in discussing with Hapi users who are crossing the moat. Interesting answer. I was just feeling sorry of myself for how things turned out. You delivered as promised and there's no grief on my end. I know why I decided the way I did, and faced with the same scen
  21. Just as a follow up and to leave trace for others who might be interested in the future: I contacted ferenc and he confirmed B-side doesn't work with Ravenna. He connects Hapi and streaming PC both to A-side, obviously not going across the moat. Yet he hears and improvement vs a regular Gigabit switch. BTW, very unfortunately my late Feb eR was delievered in the US but is grounded there per COVID so will be some time until I can try it. Oh well. Not so bad in the bid scheme of things.
  22. Could you elaborate? You wouldn't because it wouldn't work, because it would degrade the sound, or other?
  23. Not as easy to answer as the computer hosting it is headless, running Win Server 2012 R2 in minimal server mode so not easy to start up Acourate and look. As I have more time these days being locked in I will take a look and revert. Have you tried the Acourate website? Might say so. I haven't as I don't have the Hapi. Uli confirmed he has set it up. And another user running 4-way digital XO with Hapi has too. So works!
