  1. Playback is usually only as good as your network connection to your mobile device. The Qobuz app, and others, give you options to set maximum streaming resolution to your phone depending on whether you are on wifi or using cellular data. I think most phones support 192/24 with their native dacs but then you can, as you mention above, feed the digital stream through the phone to an external dac. As far as MQA goes, that's a solution in search of a problem IMHO. Getting the right version/mastering is much more important that the resolution or audio format. Reminds me of DiVX from the 1990s. Roon Arc has been pretty awesome so far.
  2. A couple other reasons in favor of a 2-channel integrated amp: 1) If you don't want your sources (you have a TT and maybe a nice DAC) to be re-digitized and routed through the internal processing of the Denon, then a separate 2-channel integrated amp is the way to go. 2) Analog tone controls. I kind of like them. One consideration is how to integrate your 2-channel and HT. If your Denon has pre-outs, look into a 2-channel integrated with home-theater bypass. Or, there are speaker switching boxes out there that would switch your Heresies between the Denon and the 2-channel. Good luck.

  4. Thanks Roy. Did the LS2 have any tweaks to the AL4 during its production run like Bob indicated in his 2009 post?
  5. It appears like somebody in the marketing department decided to call the latest La Scala "AL5" even though the LS2 had been using the AL5 crossover for 15+ years?
  6. Did Klipsch refer to them by those names? Seems weird to have a La Scala 2 with an AL-5 crossover, then 10 years later, come out with a La Scala AL-5 with a new tweeter.
  7. To add a wrinkle to the discussion, in this 2009 thread, Bob Crites talked about tweaks to the AL-4 and AK-4 networks. Bob called the modified crossovers AL-5 and AK-5 but maybe these were not the official Klipsch names? Maybe they should be called AL-4v2 and AK-4v2.
  8. Yes, or figure out how to do a factory reset of this AVR. google search.
  9. According to the manual (RTFM), those two sub outputs (#6) are identical - intended for dual-sub home theaters. The output coming out of them depends on how you configure the other speakers in the AVR (large vs small, cutover frequency etc). You could have them configured to only output the LFE channel which may explain the spotty output. In other words, they are not a traditional line-out like the "pre/line out zone-2 and zone-3" outputs that output a full-range signal.
  10. Welcome! Lots of variables here but you have a nice budget. I'm assuming you want a home-theater setup. I would look for a pair of Heresy 3's or Cornwall 3's and a nice subwoofer. Then go to accessories4less and pick out your favorite AVR - just be sure it has a full set of pre-outs in case you want to add a dedicated amp down the road. This requirement puts you into a better class of AVR regardless of the brand. Then fill in the rest of the speakers - center, surrounds.... Enjoy.
  11. Yes, it appears like it is downsampling from 96/24 to 48/16, but first it increases the bit depth from 24 to 64 to help with the math accuracy. I'm guessing volumio accepts 48/16 max?
  12. My hearing has improved as I've gotten older. I am now able to tune-out just about anything my wife says 😀
  13. I have an older Yamaha AVR and I've noticed that YPAO is sensitive to where the mic is placed. My old AVR only has a single mic placement to determine YPAO corrections. If I run it with the mic in the middle of the room (bass null), the bass gets set way too high during movies. The opposite is true if I run it with the mic close to the back wall (bass peak). I have to find the sweet spot and then YPAO works very well. I last ran REW on my stock LS2's over a year ago - by themselves, the sub alone, and then blended. This is without the Yamaha AVR in the path - strictly 2-channel. You can see I have a bass null in my room around 50hz and a peak around 30hz. RED = stock LS2's alone GREEN = sub alone BLUE = blended
  14. REW has a room simulator module that's pretty accurate. Click on the room-sim button on the top right and enter your dimensions, speaker locations, and listening position. It will tell you where the room hot spots and nulls are below 200hz.
  15. I don't know much about Roon multi-channel, but here's a help guide that may help: https://help.roonlabs.com/portal/en/kb/articles/multichannel#Overview
  16. Yes, Airplay streaming supports max 44.1/16 and then is handing it off to the DAC in your Marantz. Roon is down-sampling to 44.1/16 using the DSP - SRC filter you have selected for the Marantz. There are four to choose from in Roon. I'll be damned if I can ever tell a difference so I just go with precise-linear-phase. I'll be damned if I can tell a difference between 96/24 and 44.1/16 streaming either.
  17. Roon can be bit perfect if you configure it that way. Your signal path will tell you what it is doing to the bits.
  18. Not 100% sure but I believe streaming audio over ethernet or wifi to Shield tops out at 48kHz. Over HDMI you can go to 192kHz. Roon is adjusting automatically.
  19. Just a few comments on the posts above from today. Yes, Roon can suck in your local library, as well as your Tidal and Qobuz accounts, and internet radio, apply really good meta data to it in it's own local DB, and then stream it out to any supported Roon endpoint (roon ready, roon tested, airplay, sonus, chromecast...). All controlled from an App. It supports any music format I can think of. Roon can be configured to send the original data bits without any modification to those endpoints, or it can apply just about any amount of fuckery you desire: SRC, DSP, EQ, convolution filters.... Jriver and Audirvana can do this too - they may have any edge with izotope SRC but they lack the metadata DB that Roon has. That is the real value of Roon - it's metadata, hyperlinks, recommendations - it opens up whole new worlds (especially if you have it linked to Tidal or Qobuz.) I've been using Roon for 4 years now. I came from iTunes and Audirvana. It took me at least a month to get used to Roon. Roon would prefer you use "tags" but I still create playlists and my Qobuz playlists also sync up with Roon. When I first told Roon to import my local music library, it got about 75% correct. I had to spend a lot of time going through my Albums to edit metadata. Roon does have a lot of import preferences to help this process now and has come a long way. Just an FYI.
  20. Yes, the MDC is a "smart NIC" that runs BluOS as well as built-in code from Roon (it's a Roon ready device) that allows Roon Core to stream music directly to it via Roon's proprietary streaming protocol (RAAT) over TCP/IP. Note when you have it setup this way, you may see two entries for the MDC in Roon under settings-audio - one "roon ready" entry and one under "other roon devices" via Airplay. I believe the MDC supports Airplay and so does Roon. You want to enable the "roon ready" device.
  21. Streaming stereo hi-res audio requires relatively little bandwidth. CD quality is 1.4mbit/sec. hi-res 192/24 is around 10mbit/sec. Even if you double this for protocol and transport overheads, most internet plans can easily handle at least CD quality streaming audio. Most properly configured home wifi networks can too. Video is a different story - providers like Netflix, Amazon Prime etc all have home internet minimums for various levels of video quality. Most require a home internet service of at least 25mbit/sec for top quality video 4K/8K - more if there are other devices in the home using internet bandwidth.
  22. You want to see Roon recognize the M32 at the end of the line with an IP address as rplace's screenshot shows above with his NAD T758. Your music tests that you found irritating were done with the OS Mixer at the end of the line - meaning your Window 8.1 laptop was performing a lot of fuckery with the sound.
  23. I can't remember if you said your M32 has the DD BluOS MDC module? I thought you did but then you mentioned your Win8.1 core is directly connected to the M32 via hdmi. Can you clarify? Also - when you click on the signal path, do you see a picture (or at least the name) of your M32 at the end of the line? This would confirm that Roon recognizes your device.
  24. Roon can span the gamut from no-color (the file is sent bit-perfect to the endpoint DAC) to lots of color (SRC, DSP, EQ etc). His signal path screen shot should tell more of the story.
  25. When listening to Roon, can you post a screen shot or two of your signal path? - it's the colored icon to the left of the previous-track button at the bottom of the Roon app.
