  1. I think the best way to think about this is that all stereo systems are about compromises. And different people hear different things so they tend to emphasize on different things in their stereo system. Our ears are very good at tuning out sonic anomalies. Otherwise, we wouldn't be able to pick out a specific conversation in a noisy room. For some people DACs matter a lot sonically and for others, if the DAC measures great, they all sound the same. For some people, active crossovers that you prefer matter a lot more and for others like myself, I think there are so many sonic issues that
  2. Right. So this is the challenge with Dirac. With your HT, is it because your frequency response curve is not optimally setup that you have a more narrow soundstage? Is it because your ?subwoofer or your left or right speakers have a phase cancellation that causes an additional dip when they're playing in sync that you won't see on individual channel measurement with Dirac that's causing a loss of soundstage? There is no easy way to know. You can experiment with the frequency response and nothing else. With respect to HomeAudioFidelity vs Mitch Barnett, I've seen them post on Audiop
  3. So re-reading your post, I noticed you already have a UMIK-1 microphone. The advantage of miniDSP SHD studio is that you can run Dirac yourself. So if you already have it, you might as well just use it. The main disadvantage is that most hardware Dirac solutions involve automatic ASRC converting your 44.1kHz music to 96kHz before running Dirac. Now depending on your system, the conversion may not be audible to you but as you upgrade the rest of your system, you may get to a point where this conversion becomes a bottleneck in your system. By comparison, a dedicated convolution filter runni
  4. I think you already know what kind of DAC you like and ones that you don’t like so I actually think that a DAC upgrade may not be the next best upgrade for you. Do you have a microphone to measure your frequency response given the room acoustics? I strongly suspect a well constructed convolution filter (that you make yourself with Acourate/Audiolense) or one that you hire somebody to do (Mitch Barnett’s https://accuratesound.ca) would probably the most bang for the buck upgrade for you since you can just load the filter into Roon.
  5. Hmmm. It’s in my signature? I use my ancient PC (i7-3770k) as my Roon core with my music files stored in an ancient DS211j NAS playing into UltraRendu that is connected to Peachtree X1 to convert to Toslink feeding my Chord M-Scaler then Chord DAVE then Chord Etude into the Dynaudio C1 speakers. I used to have Sunfire subwoofers integrated like you do with your Dynaudio with the DAVE feeding them but I took them out as I may get a new pair of speakers soon. So I’ve made a few convolution filters for the old setup and for my current no subwoofers setup. My living room is untreated and
  6. 1. You should just be able to load the convolution files onto your Qnap NAS. You can check it in Roon DSP section for your zone. The bigger question is whether your Qnap NAS can run the convolution. That would depend on what CPU your Qnap uses. No way to know until you try it? I don’t think convolution is that processor intensive. 2. I don’t know how accurate your EMM-6 microphone is. I guess ideally you want a calibrated microphone. I personally use the miniDSP UMIK-1 microphone. The other issue is that if your computer is connected to a USB microphone and a USB DAC, sometimes (or maybe
  7. 1. If Metrum Ambre is your Roon endpoint, what is your Roon Core? I really don’t understand your question. If you’re already running Roon, you have to have a PC or another computer running Roon Core. You run the convolution filter on the Roon Core. How are you currently using Metrum Ambre? 2. Dayton Audio EMM-6 is fine. Just make sure you have the calibration file 3. I actually read through Mitch Barrett’s book Accurate Sound Reproduction Using DSP to learn how to use Acourate. I just bought the Kindle version. But I guess you can start with Archimago’s instructions. I personally don
  8. 1. Different people have different preferences on the ideal frequency response curve: https://accuratesound.ca/standards Some people like a few dB higher in the bass. Some people want 20kHz to be at -10dB lower while others prefer only -4dB lower than the rest of the frequencies. When you create the convolution filter in Acourate, you can choose what target you like. It is impossible to guess your preference so you have to basically create a few optimized filters with different target curves and just listen to what you like best. I do find that knowing what your current system’s freq
  9. Right. Because to use Acourate to optimize for your current system, you have to: 1) Pick your preferred target frequency response 2) Learn how to optimize the time-domain filtering, aka. Optimize the excessive phase windowing parameters And then you can even do more within Acourate because 3) if your speakers/subwoofers are asymmetrically setup in a room, you can do phase correction to avoid cancellations when sound is coming from the middle and your left & right channels are cancelling each other at specific frequencies 4) if your dominant room mode is the
  10. My take is that if you’re going to do this yourself with Acourate, you should just start now with your current system rather than spend any money trying to build the optimal active DSP speaker system. Sure, the crossover between your subwoofers and 20.1 won’t be optimal. But Acourate has a fairly steep learning curve. So to me, being able to create a great convolution filter for your current system by treating it as a normal 2-channel one, would allow you to more easily optimize future filters for active 2-way/3-way systems in the future. It would also give you a better idea based on your
  11. Huh. Super interesting. I wonder: 1) when your Node 2i is on Wireless, whether your router puts it on a higher priority and allows MacMini Roon to communicate with it more consistently than when you had it on wired where your router might have been blocking/reducing the traffic 2) if one of your network switches connected to the Node 2i is de-prioritizing (less likely) or blocking/reducing communications between the MacMini Roon to the Node 2i. If your home wi-fi is super stable (which actually isn't super difficult to do if you know what you're doing as it's mostly abou
  12. I think re-reading what @Ron T had posted, the USB connection to a DAC is a red herring. Just to verify, the main problem is: He cannot play anything using Roon to Bluesound Node 2i. No local audio files playback from Roon to Bluesound Node 2i No Tidal files playback from Roon to Bluesound Node 2i And he is able to use Roon to play music (audio files/Tidal) into his USB DAC which is connected to his Mac mini which is the Roon core/server. To me, it is always possible that there is a software issue between Roon and Node 2i although I believe Ro
  13. Wait a minute. The Tidal media is loading slowly is a different problem. It means your MacMini Roon is not connecting to Tidal. Maybe you need to log out of Tidal within Roon and try to re log in.
  14. Ah. A picture is worth a thousand words. Bluesound is a RoonReady device. So it shouldn’t say Airplay on the zone. you need to remove this bluesound zone. And then try to setup a new one where the bluesound is recognized as a room ready device.
  15. Another way to explain it is that you can have Roon play on two DACs. You can have Roon play USB into USB non MQA DAC while playing music to the Node 2i/DAC at the same time. what you cannot do in Roon is to have Roon play USB into the non MQA DAC at the same time as Roon playing into Node 2i playing into the non MQA DAC at the same time. you can’t have Roon play two streams of the same music into the same DAC at the same time if the DAC is connected via USB as one of the connection methods
