  1. No, @Kal Rubinson, but I have Redscape Audio’s headphone software bedside. Not only does it credibly recreate a real 6 channel surround environment for MCH tracks, it enhances the soundstage for 2 channel tracks played through it. So, I get the idea. I’ve never used any of the Marantz options. What option would you say I should try and for this test, is using the built-in non-pro Audyssey adequate? Thanks. JCR
  2. Yes, speaker and room correction, @Kal Rubinson. When we last exchanged messages on the topic of Audyssey, I was considering paying up for a pro license for my 8802A as I have the pro kit. Your recommendation then was, paraphrasing, to use Audyssey pro only if one of the more current softwares were unavailable. So, I didn’t buy the Audyssey license. Instead, I went down the Audiolense XO path and have been totally happy with the decision, notwithstanding the Roon MCH channel mapping issues that you and I both have been plagued with. So, are you suggesting that for this s
  3. Sorry, @Kal Rubinson, but I am now slightly confused. I totally get that I can't use the 7.1 analog inputs for Auro-2d. But, you reference using stereo analog inputs, which would imply a stereo output. Or, is the signal path that is workable something like this: Source stereo file on NAS or streaming from Tidal ---> Server for convolution and Roon playback ---> analog stereo input on Marantz, applying Auro-2d ---> 5.2 output to amps and subs Put another way, does Auro-2d cause the Marantz to take the stereo input and create a surround environment with it? I
  4. Ok, @Kal Rubinson. So, I’m unclear as to whether a 5.2 surround arrangement will work fine for Auro2d — and I’m interested in your experience using the 7.1 analog inputs on the AV-8802A as to whether that input set can support Auro2d. Thanks. JCR
  5. Ok, understood, @Bill Brown. My MCH DAC is the Okto dac8pro. It’s connected into the Marantz via the 7.1 analog inputs. @Kal Rubinson, will Auro2d run on that set of inputs into an AV-8802A? JCR
  6. So, Auro3d requires no further speakers or amps. Let me understand the arrangement, @Kal Rubinson. In my main system stereo setup, Roon is my playback and Audiolense convolution engine, running through my Bel Canto streamer, which will do the second MQA unfold. Then, I run into the Marantz stereo input where Audyssey is shut off, but bass management is still active. (I have a 2.2 setup for stereo and I ran my Audiolense filter measurements with the Marantz bass management in place.) Can I turn Auro2d alone on for a single input of that sort? Thanks. JCR
  7. @Kal Rubinson, what do you use for a height channel and where do you place it? And could you offer a track or album that you believe best demonstrates the effect you note. Thanks. JCR
  8. Hey, @Kal Rubinson. What do you do with Auro, and is it also in my AV-8802A? Have you tried the above referenced ESI Gigaport ex MCH DAC yet? Just wondering if you think it sounds better than the old miniDSP u-DAC8, which I still have in service on my porch system. It certainly is inexpensive. For $161, I ordered one today just to try out. Thanks. JCR
  9. Ok, @Kal Rubinson. I am now happy to report great progress. For MCH with the Okto, I am now using HQP desktop in my new server through a microRendu and all tracks upscale to native DSD128. In addition, I have worked together with Bernt from Audiolense and Jussi from HQP to successfully map (manually, at this point) AL MCH convolution filters into the HQP convolution pipeline matrix. So, the system path now runs ASDM7 with convolution (still can’t do ASDM7EC in MCH at native DSD128, though, as Jussi says can’t be done in MCH with any processor on the market today). Impressive sounding. W
  10. @Kal Rubinson, how then are you running the Okto for MCH in Roon? JCR
  11. @Kal Rubinson, resource manager tells me that when the Okto runs, I get to about 26% CPU usage. msconfig has an advanced setting with respect to cores (10 of them on my processor). From what I read, so long as the box there is not checked, the operating system automatically uses the number of cores necessary for the task. But, I set it manually for all 10, rebooted and tried. No difference. Sigh. I can’t get 2XDSD native set in DSP Studio in MC26 other than for 2 channels (the ability to select source number of channels or 7.1 isn’t available when I pick 2XDSD), and even that doesn’
  12. Ah, @Kal Rubinson, right now, I am NOT using HQP for the Okto. Maybe I should try that. But, during the 17 or so seconds that Roon is playing native MCH DSD64 out through Roon, the CPU doesn’t go past 21%. It’s sleeping and yet stuttering. I should also try MC26. I am using HQP for its virtual audio input so as to take my phono preamp output through the Benchmark ADC1 converter and run its digital output through HQP and convolution. This is for real-time vinyl playback and is outside of Roon. I can scale there from 32/192 out of the Benchmark to 44.1x256 with ASDMEC7 in HQP
  13. @Kal Rubinson, it’s an i9-10900K processor, 32Gb of RAM, and an EVGA GeForce RRax 2080 Ti XC GPU for HQP CUDA offloading. With my old i7-4790 processor and 16Gb of RAM, I could do DSD128 with convolution on HQP but not DSD256. Now, I can do that, but not DSD512 in HQP without stuttering. It never gets taxed so I don’t understand the issue. Chris Connaker thought it was the 966K of taps in Roon, but that’s offloaded to the GPU anyway and disengaging convolution still doesn’t solve the problem. On the Okto side, with the old processor, it worked fine for 8-channel at 24/192. No bette
  14. I posted over at the Roon forum on this issue, as well. I’ve built out Chris Connaker’s new CAPS20 server with the anticipation that I would be able to use it with USB out to the Okto DAC via the Okto-supplied DIYNHK driver and play multichannel files natively up to DSD128 with convolution applied. Frankly, the native DSF multichannel files that I have are DSD64, so not even as demanding. But, all I get is stuttering and Roon loses control after 15-17 seconds of playback. In particular, I hope that @Kal Rubinson will weigh on on what he’s been able to do with the Okto using his Pink Faun serve
  15. I input into my PC server using HQP Desktop, which has a digital input accessed via a soundcard in the PC. In my case, I have a Lynx AES16e card in my Roon server, the input to which is from my Benchmark A-to-D converter. I use the Benchmark to digitize vinyl playback real-time, and then I apply Audiolense convolution filters stored on the server through HQP to get sound-corrected vinyl playback. Right now, I upsample to DSD128 in HQP for playback, but as soon as my new server is ready, I expect to upsample vinyl playback to DSD512. I suppose you could substitute an outboard CD player for my t
