  3. OK, after a month with the Unison in place in my Yggy with ISO Regen/LPS-1 in place and finding the sound very nice indeed, I recently removed the Uptone equipment. My conclusion is that the sound was somewhat improved by removing the Regen and LPS-1. Not in areas like detail or musicality, but dynamics were enhanced. This was noticeable at all playback levels, not just in low-volume settings, so not precisely the "lower noise floor" effect. Now, it should be noted that since the last time I tried this experiment, when I still had the Gen 5 board and reached the opposite conclusion, I have significantly upgraded my USB cable from a $10 Belkin Gold to a $650 Synergistic Research Atmosphere X. It is possible the Regen improved the sound of the Belkin USB cable, the Gen 5 board, or both. I have not tested sufficient combinations to say so definitively. Specifically, because I have no intention of going back to the Belkin cable, I have not experimented with the Unison+Regen+Belkin combo. So there are confounders aplenty in my limited scope experiment that probably mean it would be inconclusive for anyone not using the same equipment and in the same (limited) combinations I tested. Bottom line for me, however, is that I have heard enough improvement from using the Unison+SR Atmosphere X USB cable combo - without Regen/LPS-1 - that I am going to take the Regen/LPS-1 out of the system indefinitely. Others can take from my results the conclusion that they *possibly could* find improvements from *not* utilizing the Uptone equipment with the Unison board. It is at least worth the experiment for those who already own the Uptone pieces.
  4. A possibility I plan to investigate! But it will take some time. I have learned that, in my own case, attempting quick A/B comparisons rarely results in any definitive discernible difference (there have been exceptions, just not many). My MO therefore is to make a change, listen to it for a month or so until it becomes the "new normal" to my ears, and then put things back the way they were (remove the added equipment, reinstall what it replaced, etc.) and listen to see whether that makes it sound different, better or worse. It would be impractical to switch back to the Gen5 USB, but I certainly can do a slow-listening comparison to Unison with and without the Regen. So I promise to try removing the Regen in a month or so and to check back in with the results! (Also, at risk of abusing the Edit window, I definitely found the Regen to improve the sound of the Gen5 USB. I listened to my Yggy for about a year without the Regen after Schiit declared USB was "solved" by Gen5, but when I eventually tried reinserting the Regen - after being fully accustomed to the sound of Yggy/Gen5 USB without Regen - it sounded dramatically better, to the point where I wondered why I had wasted so much listening time without the Regen. So there's that.)
  5. I have a similar problem sometimes with my ISO Regen/Yggy combo. Unplugging the Regen from the DAC and repluggjng it often fixes the problem. If that doesn't work, powering down the Regen (unplugging the DC power cable) and repowering it will usually fix it. When those two measures fail, I also power cycle the DAC combined with doing both of the above a second time. 90% of the time, one of these three approaches fixes the problem. In those rare instances where this doesn't do the job, I have also restarted my Mac Mini; however, from your signature line, that doesn't seem directly relevant to you. Hope this helps!
  6. I have bought and installed the Unison board in my Yggy, and while I was heartened to find when I threw the switch that I hadn't actually destroyed my DAC and it functioned perfectly, I have been struggling a bit to hear any changes to the sound. Maybe this is because I was using the ISO Regen before and after the change-up to the USB input board. Maybe it's also partly attributable to a recent upgrade I made to my USB cable, from a basic Belkin Gold to a fancier one (Synergistic Research Atmosphere X), which could be confounding the comparison. I don't regret making the Unison USB board upgrade, as it cost only $150 and may yet yield some audible improvements. So I may or may not have answered my own earlier question about how the Unison interfaces with a Regen. Anyone else with a Regen and who's made the switch to the Unison board have a different or more clear set of impressions? Sorry for my seeming ambivalence; I might just be posting too soon after making the switch 24 hours ago.
  7. A query to any Schiit DAC owners who decide to install the new Unison USB input upgrade. Could you relate here how that affects the sound in conjunction with an Uptone Audio ISO Regen. On the Yggy in particular, but with other DACs, as well. Thanks

  9. And while we can always hope that Dirac somehow manages to turn back the dial to allow Roon + Dirac as endpoint, until such time there are alternative solutions. The one I chose is Home Audio Fidelity (HAF), which with its crosstalk correction actually has one big thing up on Dirac (voices reproduce better and stand out from background music better an more realistically). That said, the impulse response control with Dirac was intoxicating, especially for a lover of jazz or other music with a lot of percussion or pizzicato. So there is a trade off. But from the practical perspective, HAF wins hands down. HAF creates convolution filters from your measurements that work beautifully with Roon, no Audio Hijack or other applications required. You can't fiddle around with your measurements and filters like you might with Dirac, as you have to pay HAF to process your measurements for you and create new convolution filters files whenever you materially change your listening room or system. But if your listening room and system are not likely to have any material changes in the foreseeable future, locking into something like HAF's convolution filters files is just fine.
  10. That could be, as I did try with no success to use an early Dirac Live 2 beta. However, the problem originally arose with Dirac Live 1.x. It showed up spontaneously when I moved to the new 2018 Mac Mini with updated Mac OS late in 2018. Again, the problem was that before the OS upgrade, I was able to select Dirac Live 1.x as a Roon endpoint (where my 2011 Mac Mini was serving as the Roon core and also running Dirac Live application), but immediately after I switched to the new Mac Mini with updated Mac OS and tried to run the same programs in the same way, I was no longer able to do so - i.e., I could run Roon just fine, but I could no longer open Dirac Live and point to it in Roon as a Roon endpoint. Audio Hijack was a workaround suggested by Dirac that, as I noted above, worked but was not 100% satisfactory. I very much look forward to trying Dirac Live 2, final non-Beta version, to see whether it plays well with Roon on my 2018 Mac Mini running the current update to Mac OS (Catalina)! Let me know when the license transfer for Dirac Live 1.x licensees such as myself becomes available. Thanks!
  11. I was able to use Dirac Live as an endpoint with Roon for several years. I had both Roon and Dirac Live running on a 2011 Mac Mini. In autumn 2018, I upgraded to a 2018 Mac Mini, and with that to the then-latest version of Mac OS. At that time, it became no longer possible to use Dirac Live as an endpoint with Roon. Dirac did tell me at that time (early 2019) that Audio Hijack was a work-around, and I was in fact able to use Dirac Live as a plug-in with Audio Hijack and could get Roon to play with Dirac Live in that way. However, it is an awkward work-around that also, to my ear, degraded the sound quality of both Roon and Dirac Live. Perhaps the issue is compatibility between Roon and Mac OS updates since autumn 2018? Or something about the combination of Roon, Dirac Live and 2018-and later updates to Mac OS?
